Description

FIELD OF TECHNOLOGY

The present invention relates, in General, to systems, apparatus and methods applicable for selectively performing operations in passages formed in underground formations, for one or more wells operating from the same main trunk, for the construction and operation of injection and / or production wells, essentially hydrocarbon or essentially water.

BACKGROUND OF THE INVENTION

Hydrocarbons are mined from underground zones and reservoirs also containing water and other associated fluids. In many wells, the volume of water and other downhole fluids can significantly exceed the relative volume of hydrocarbons produced from the wells, so that hydrocarbon production rates can be reduced or limited by the volume of water and other fluids transported by downhole fluid production systems. Traditionally, the separation of hydrocarbons from water and other downhole fluids during hydrocarbon production occurs on the surface. In addition to surface separation systems, downhole fluid production systems are used, including electric centrifugal separators or permeable filter systems and / or hydraulic or mechanical separators to separate hydrocarbons from other fluids in the well. However, these existing downhole systems require power, moving components, and / or periodic replacement of devices or parts, so that these existing systems do not work efficiently during the entire life of the well. In addition, these traditional systems do not provide for the separation and selective control of continuously flowing streams, including the selective direction during injection under pressure, essentially of hydrocarbons or essentially water and / or production streams, in one main wellbore.

Embodiments of the present invention can selectively control simultaneously passing fluid flows at varying speeds through the use of flow control elements. Flow control elements may be selectively installed between pipes of a plurality of concentric pipe columns or, alternatively, installed through passages closest to the center line and connected to one or more receiving sockets of the underground pipe column system using at least one distribution sub with radial fluid communication passages medium between concentric passages and one or more pipes passing down. The pipe string system can be used to pump fluid into, and / or to extract fluid from one or more wells located vertically and / or horizontally in areas of subterranean formations passing through one main wellbore and wellhead equipment, thereby minimizing the required space, drilling rig movements and / or ground facilities.

In embodiments of the present invention, flow control elements can be used to selectively recover and / or inject essentially hydrocarbon or essentially water-based fluid mixtures containing gases, liquids and / or solids, for example, to dispose of drill cuttings or removal of saturated brine through a pipe string system sub placed between two or more subterranean formations at the lower end of one or more wells that may be contained in one main wellbore other. Fluid mixtures can be obtained and injected selectively along one main wellbore, for example, water is injected, receiving steam generated in a deep geothermal underground zone, or pumping it into tar sand collector or cold Arctic collector for heating and production of viscous hydrocarbons. Fluid mixtures can be selectively injected into or removed from one main wellbore to recover liquid waste or oil contaminated water without surface treatment, or to displace hydrocarbons from the reservoir by flooding or flooding directly from a deeper underground water source with higher pressure. Alternatively, fluid mixtures can be selectively injected into or removed from one main wellbore to supply heat to a geothermal source from another subterranean well, at the intersection of the wells to produce steam or to condense reuse water during steam production. In addition, fluid mixtures can be selectively injected into or removed from one main wellbore to selectively extract gravitationally separated underground stored fluids from two different depths of the salt cavity, to dissolve the salt with water at the lower end of the cavity using the upper end for storage operations , or to separate hydrocarbon streams produced from a sand reservoir during development by dissolving a cavity with wastewater in a salt deposit forming the roof.

Embodiments of the present invention may further include systems, apparatus, and methods applicable to operating wells of many different types to supply substantially hydrocarbon and / or substantially injection or production water. Examples of produced or injected products include underground liquid hydrocarbons, gaseous hydrocarbons, underground steam, underground salt-saturated fluids, fluids for drill cuttings and fluids used in the construction or treatment of wells to stimulate flow, such as fracturing proppant mixtures, from or to vertically or transversely divided inlet or outlet throttle openings of pipes. Pipes with inlet or outlet throttles for use in injection and production direction operations can pass in underground areas from one main trunk installed under one unit of wellhead equipment. Systems and methods for delivering essentially hydrocarbons and / or essentially injection water or production can be used during, for example, construction of a well or underground storage cavity, and / or during production from a reservoir, underground cavity, and / or developed by dissolving a salt zone. The use in wells of various types and in various applications provides the necessary profitability for standardizing systems, methods and devices that can be performed in various configurations, for example, for deploying a wide batch production.

In an additional aspect, embodiments of the present invention can provide systems, methods and devices for controlling fluid mixtures containing solid particles. Examples of such fluid mixtures may include proppant fluids for fracturing in shale gas production, fracturing reservoirs of low permeability, or installing gravel packs in unconsolidated reservoirs. Conventional technologies using serial equipment for placement of solid particles use a two-stream approach, which does not effectively solve the problem of the geological properties of impermeable shales, since devices developed for sand reservoirs with the ability to remove solid particles from the wellbore after proppant loss are used. However, embodiments of the present invention provide for the placement and removal of excess solid particles in a vertically and / or in plan divided underground zones, from one or more wells from one main wellbore to increase the productivity of less productive, essentially impermeable, shale reservoirs or dense sand or unconsolidated reservoirs through improved placement and recovery of fluid mixtures containing solid particles.

Embodiments of the present invention may additionally use fluid-rotated devices mounted on a cable, such as drilling, cutting, and pumping devices. These devices are applicable for installation of flow control in a well, during construction, geotechnical measures, operation and / or conservation of various types of wells, using downhole assemblies run on a cable that can be selectively installed, suspended and / or removed in pipe string systems, on a cable using a cable lift.

Embodiments of the present invention can provide a hydraulic pump, a flow control element that can be used in hydrocarbon, water, and / or underground storage wells with an electric or hydraulic motor. The engine may be driven by a stream of injected water or an expansion of a higher velocity fluid stream, such as an expansion of a gas or fluid stream from a deeper, higher formation pressure, which can be used to pump a low velocity fluid stream, further with directing it under pressure from the well or into the well.

Flow control elements can selectively control one or more distribution sub, creating changes in the fluid flow rate, which can be used to selectively emulate a high-speed lifting column, jet pump and / or venturi device during production, injection and / or downhole processing.

Embodiments of the present invention may also provide a means for selectively separating a fluid mixture stream into a plurality of substantially gaseous, liquid and / or water flows at varying speeds and corresponding recovery or injection flows. The configuration of the separation of flows can be selectively changed using a cable tool using a cable hoist or other drilling rig, which can be used during or during the life cycle of one or more essentially hydrocarbon and / or essentially water wells operating through one main wellbore and equipment. Elements of a system of pipe columns can be used to control the flow passing through the passages and the spaces between the pipe columns in one or more underground zones, due to, for example, using the space in the passages through underground layers and / or walls of the cavity for underground processing of production and / or injection before or after passing through the wellhead equipment, to reduce the required surface treatment facilities.

Embodiments of the present invention are also used during underground separation into a first substantially gaseous fluid stream and a second substantially liquid produced fluid stream to selectively control a gas lift of the second fluid stream. This underground separation and selective control can be performed by controlling the injection of at least a portion of the first stream into the second stream, before each of the streams leaves the wellhead equipment or fountain fittings at the upper end of one main trunk to selectively optimize the extraction process and the result flow.

Embodiments of the present invention may additionally provide a means of heat influencing the flows by selectively controlling the adjacent passage or separated in plan plan wells, which may extend downward from the intersection of the wells, for example, to prevent heat transfer between the passing fluid flows during dissolution or heat transfer for heating the productive layer of tar sand or a cold Arctic layer, through the use of an adjacent passage through one novnoy trunk and / or intersection wells for injecting steam into a vertically and / or in terms of a point separated at the intersection of wells. In addition, selective flow control provides thermal insulation of the flow, for example, through the use of wastewater obtained from hot fluids, for example, by separating hydrocarbon or condensing steam in the process of generating electricity, which can be pumped axially downward through the passage of one main barrel to insulate the product extracted axially upward from the cooling effect of the strata and / or ocean. Another example involves the use of injecting colder wastewater through an element of a concentric passage of thermal insulation of equipment from high-temperature production created by a deep hydrocarbon or geothermal source. Other examples include thermal insulation of flow control elements such as the shoe of the last casing string with cementing the salt cavern of the gas storage during simultaneous extraction of gas from the underground storage and dissolution operations.

There is an economic need to create systems, methods and devices applicable to minimize the amount of equipment and space required for the construction and operation of a variety of wells located in places with high environmental protection requirements and in remote areas, including, for example, urban areas, jungle, arctic or marine areas.

There is a need to create economies of scale required to develop compatible systems, methods and devices applicable to many different types of wells, including, for example, hydrocarbon, geothermal, water production, underground waste disposal, underground storage and dissolution development wells, while The widespread use in wells of many different types gives cost-effective standardization and serial deliveries.

The scale and economic requirements of recently discovered hydrocarbon reserves of shale gas in impermeable reservoirs around the world, and of reserves in unconsolidated reservoirs, of low profitability, require the creation of systems and methods for improving the management of fluids carrying solid particles to separate sand from a solution in unconsolidated formations or initiate and the development of cracks in collectors, where the removal of solid particles and / or crack lengths are limited, in order to increase the relative permeability of, for example, collectors gloss or gas, for example, improve the gravel pack in unconsolidated reservoirs for the limits of the possible in the present and / or profitability obtained using conventional techniques which are generally designed for rich or permeable reservoirs.

There is a need to create systems and methods for reducing waste in the form of by-products of open mining of tar sands and reducing the impact of ground structures on permafrost zones over Arctic reservoirs, while the heat and / or pressure from geothermal and / or deeper wells that serve as their sources , can be directed through the intersection of the aisles of wells for heating and extraction of viscous hydrocarbons without intermediate preparation of a heat source on the surface of the fluids.

There is a need to create improved systems, devices and methods applicable for better transfer of particulate matter in a completion column to place proppant cracks or gravel packs in shale gas reservoirs or unconsolidated reservoirs, respectively, associated with the need to supply gases, liquids and / or solid particles for more efficient extraction during removal of particulate matter or sand.

There is a need to create systems and methods for operating one or more wells using a reduced nomenclature of ground equipment and lower labor costs for working on a wire rope or cable during the life cycle of wells before conservation, while selectively controlling fluid flows from multiple wells going down from one main wellbore, improves the overall profitability of production, injection and / or final preservation, for wells of many different types to improve profitability spans of underground mining with low profitability, such as shale gas, tar sands, interbedded marine reserves, structures of marine underground storage facilities and / or various other developments requiring technological improvements for development.

There is a need to create systems and methods that are applicable for production from one main well while pumping water through one main well into many wells, for example: liquid waste and / or to perform water flooding to maintain pressure, reduce subsidence or displacement in the reservoir. In addition, there is a need to create systems and methods that are applicable for production from one main well while pumping water through one main well into multiple wells for supplying consumable water to underground steam generating manifolds, for supplying heat to viscous hydrocarbon reservoirs, and / or storing and retrieving stored materials from caverns using the stored product as a leach buffer during development by dissolving some caverns.

There is also a need to create systems and methods applicable for the use of energy, for example, water injection, expansion of underground fluid, electrical and / or underground pressure sources for driving pumps installed between pipes or selectively installed through pipe passages in receiving sockets, such submersible submersible pumps are applicable with a pipe string system for simultaneous injection and / or production operations. These injection and / or production operations can be used to facilitate, for example: the placement of feed water using steam expansion or condensation of reuse steam in a geothermal well; the use of liquid waste injection to drive submersible pumps that raise produced fluids; using gas expansion in a production process or an underground separation process to drive a turbine used to pump fluids from a well; expanding the gas from the caverns of the underground storage facilities to drive the pumping water turbine into the overpressure storage space to maintain pressure in the cavity and / or developing by dissolution (followed by injection of compressed gas reversing the pump to facilitate the pumping of the brine of their underground storage space); or using a deep water source to drive a turbine or screw engine and / or pump for production in a depleted hydrocarbon reservoir, after which a higher pressure from a greater depth is naturally pumped into a weaker shallow formation for disposal.

Additionally, there is a need to create underground high-speed lifting columns with a variable configuration, and underground separation systems and / or gas lift systems, methods and devices applicable for selective regulation of underground processing before passing through wellhead equipment or exiting from fountain valves. These systems and methods can provide selective control, due to the use of flow control elements of the pipe string system, for example, for the operation of underwater or unprofitable developments, where surface processing may be impractical and where configuration of the pipe string system elements is possible during the well life cycle, without the need to remove the production string, thus, the life cycle of one or more wells is potentially extended under one m main trunk.

Finally, there is also the need to create systems and methods that are applicable for thermal effects on wells, for example: isolating flows by separating wellbores and flows below the intersection of wells. The thermal effects of these systems and methods may include maintaining the heat of the injected fluids during salt dissolution to improve the salt saturation level of the brine to be removed, reducing condensation during steam production using heat insulating warm wastewater, an injection stream, such as supplying a geothermal reservoir to reduce time reuse of water, or thermal insulation of hydrocarbon production streams using the heat of injected waste water to increase stored I heat flow passage and guarantees in the cold environment of the ocean and the Arctic environment.

Various embodiments of the present invention solve the problems of these requirements.

SUMMARY OF THE INVENTION

Various preferred embodiments of the distribution sub (23K of Fig. 58, 23L of Fig. 61-65, 23F of Fig. 66, 23M of Fig. 67 and 68, 23R of Fig. 82, and 23T of Fig. 83-87) are formed by adapting the connection chambers (21 , 43) with at least one radial passage (75) for fluid communication in the passages that can be formed between the pipe columns (2, 2A, 2B, 2C, 39, 50, 51, 71, 78) and the passage through underground strata (52).

A pressure-controlled pipe assembly (49), a concentric pipe string (50) closest to the centerline, and a concentric pipe string (51) located above the slurry passage device (58) that functions as a distribution sub (23U) and communicates with the fluid through radially passages (75) with pipe columns (39) extending downward can be used to form a well intersection, additionally used by other pipe string systems (70, 76) connected to the pipe closest to the center line and (39) and concentric pipe columns (2A) after removing the distribution sub (23U) of the installation with a radial passage (75) for connecting pipes of another system of pipe columns extending downstream from the equipment (7) of the wellhead and / or fountain fittings (10, 10A).

In other preferred embodiments of the system (70L Fig. 43, 70C Fig. 44, 49 and 70F Fig. 100-105, 70G Fig. 119-120, 70H Fig. 121-122 and 76L Fig. 123) pipe columns applicable to well designs, fluid mixtures (38), such as aerated cement, reservoir flushing fluids, proppant fracturing fluid, or fresh water for dissolving salt, are accommodated using a pipe assembly (49) with pressure control with one or more devices (58) sludge passage, functioning as distribution sub (23), left on ste. In addition, the concentric pipe string (50) closest to the centerline and other pipe columns (39, 51) are connected to the adapted connecting sub of FIG. 43-44, 117-123) of the connecting chamber, which controls separate simultaneously passing flows with varying speeds with using the channel selector (47, 47A). Various pipe arrangements (49) with pressure control with one or more sludge passage devices (58) that function as distribution sub (23) are combined with various other devices and can become elements of a pipe string system when connected to the mouth equipment (7) wells and / or gushing (10, 10A) and the end of the well formation phase.

Any fluid mixture (38) of liquid, gas and / or solid particles that can be transported in simultaneously passing fluid flows in underground pipes with different speeds can be used in the passages of the pipe string system. For example, underground fluids (38), produced fluids, and injected waste fluids (38) may pass through the upper end of the wellhead equipment (7) and pass through the tubing string system (70, 76) in the same or different direction . Such directions may include a stream (34) axially up for production and a stream (31) axially down for processing or disposal with injection through concentric passages (24, 24A, 25, 26) and / or through positions (32, 33, 35 , 37) radial passage (75) with varying speeds. The flow control elements can control the flow through the passage closest to the center line (25), the connecting device (26) of the passage closest to the center line, and / or at least one concentric passage (24, 24A, 24B) for supplying a fluid mixture ( 38) from, or to, a close zone of one or more underground wells, through one main trunk (6).

Distribution sub (23, 58) may have at least one radial passage (75) to divert at least a portion of the fluid stream directly, position (32), or not directly, position, (35) through another passage integral or connected flow, in the passage closest to the center line (25, 26, 53). Alternatively, the distribution sub can have at least one radial passage (75) to divert at least a portion of the fluid stream directly, position (33), or not directly, position (37), through another integral or connected passage at least one concentric passage (24, 24A, 24B, 54, 55), with blocking the entire flow, or ensuring continued passage of part of the flow axially up, position (34) and / or down, position (31), depending from use and the supplied fluid mixture, for example simultaneous injection A flooding and water production from waterflood reservoir.

The fluid flows passing to the positions (32, 35) of the passage closest to the center line (25, 26, 53) can start directly, position (32) from another first passage (24, 24A, 24B, 25, 26, 53, 54, 55) or not directly, position (35) from the first pass through the secondary integral pass. The secondary integral passage may comprise, for example, a distribution sub (23Y of FIGS. 14-16 and 22-29) that contains a divided concentric passage or a distribution sub (23Z of FIGS. 117 and 118-123) that contains a radial passage (75) pipes (39) of the output channel through the concentric passage (24) of the adapter (21) of the connecting chamber, or by the fusion chamber of the connecting chamber and or a number of distribution adapters (23), which are directed to the passage (24, 24A, 24B, 25, 26, 53, 54) the merger and / or the first annular passage (55) located at control system (49, 70, 76) of pipe strings, and pass through the subterranean strata (52), wherein the flow passes through at least one radial passage (75) of the distribution sub (21, 23, 58).

Fluid flows passing to positions (33, 37), to a concentric passage (24, 24A, 24B, 54) or to the first annular passage (55) can originate directly, position (33) from the first passage (24, 24A, 24B, 25, 26, 53, 54, 55), or not directly, position (37) from the first pass through another secondary integral pass or mixed pass (24, 24A, 24B, 25, 26, 53, 54, 55).

The speeds of the continuous blocked and / or diverted fluid flows can be selectively controlled using flow control elements (61) that can be installed between the pipes of the pipe system (2, 2A, 2B, 50, 51), or at least one receiving socket (45, 45A) e.g. gate valves (74). Flow control elements can be installed in the receiving socket, for example, by: installing twin packers (22) in the distribution sub (23) to form high-speed lifting columns or to block the radial passage; the installation of gas lift valves (23G Fig. 49-50) in the sub or side gas lift mandrels for the formation of gas lift columns; installation of fountain valves (10, 10A) and / or valves (84) single-acting or pressure-activated valves (32W Fig. 49-50) on equipment (7) of the wellhead or in the sub for controlling columns with increased effective diameter of passage, applicable for separation of liquids and gases; shoes (16) of casing for blocking the first annular passage (55) from forcing (31) the waste sludge into the fracture (18) of the formations; and / or hydraulic motors (69 Figs. 26-38 and 42-45) or electric motors (69 Figs. 39, 42 and 44) and pumps (69), which can be installed through the passage of the pipe string system closest to the center line.

Various preferred embodiments of the systems (70 Figs. 31-35 and 42-45) of the tubing strings can be used with electric motors or hydraulic motors and pumps (69 Figs. 26-29, 31-37, 38-39 and 44-45) of the variants ( 69A Fig. 26-29, 69B Fig. 31-37, 69C Fig. 38 and 69D Fig. 39) for connection with one or more receiving sockets (45, 45A), or between pipes of the system (49, 70, 76) pipe columns using electricity and / or energy from a stream at a higher speed or pressure to pump another stream at a lower speed or pressure. For example, fluid from the first stream (31, 32, 33, 34, 35, 36, 36A, 37) can be used to drive a hydraulic turbo motor and / or a screw hydraulic motor to rotate the shaft and, thus, drive the corresponding turbopump and / or a screw pump for supplying a second stream.

Various preferred embodiments of the system (70 Fig. 22-35, 42 and 44, 76 Fig. 50-52, 76 Fig. 123) of the pipe columns can be used essentially with an aqueous fluid mixture, which is pumped axially downward, position (31 ), while the other fluid moves axially upward, position (34); examples include operation during: disposal of wastewater, waterflooding, water supply for underground steam generation, treatment for crack development, displacement of brine from the underground storage and / or injection of water for dissolution during development by dissolution.

In other preferred embodiments, the implementation of the system (70 FIGS. 22-35, 42-43 and 48-49, 76 of FIG. 123) of the tubing strings can be applied with essentially liquid fluid streams communicating axially up and / or down through the passage, in this case, essentially, the gas flow of the fluid is communicated axially upward through the other passages. Examples of use include: gas lift with underground separation of gas and liquid or without it, or the simultaneous geothermal production of steam with water injection and / or reuse of water from steam condensation during operation.

Various preferred options (70B Fig. 42, 70D Fig. 48-49) can be applied with electric, pressure-activated, pressure pulsation or acoustically activated underground flow control elements (63, 84, 85), while fountain fittings are used for selective control on the surface of the production, position (34), or injection, position (31), with the passage of electrical or acoustic signals through the housing or ring passages for remote control of flow control elements and / or for remotely activation of pressure-sensitive devices by pressure pulsations corresponding to the opening and closing of valves of the fountain valves for selective control of at least one passage.

Other preferred embodiments include a system (70 of Figs. 6-7, 22-35, 44-45 and 48-49) of pipe columns, which can be used, for example, to separate or join streams and effectively reduce the diameter of the stream to form a high-speed a lifting column of a selected length, which can be used to increase the speed and the corresponding pressure in the venturi device, for example, to increase production in hydrocarbon wells using a saturation point of a fluid mixture or for the operation of a venturi pipe (85) or ynogo pump as flow control element.

In yet another preferred embodiment, the system (70B Fig. 42-43 and 70D Fig. 48-49) of pipe columns can be used, for example, in underground processing of the fluid to reduce the pressure acting in at least one stream using the element ( 61) flow control, or gushing (10, 10A), for the formation of flow at a higher speed. For example, a substantially gaseous fluid mixture containing a higher velocity stream can be separated from a substantially liquid fluid mixture containing a lower velocity stream to create separation of liquids, gases, or combinations thereof in hydrocarbon or geothermal wells.

In related embodiments, the system (70B of Figs. 42-43 and 70D of Figs. 48-49) of pipe columns, for example, can form gas-lift devices for hydrocarbon fluid mixtures of a multiphase stream from underground processing, which then forms a substantially gaseous stream with higher speed and essentially liquid flow at a lower speed. A portion of the substantially gaseous stream at a higher rate may be injected into the substantially liquid stream at a lower rate through one or more gas lift valves, which are flow control elements connected to one or more receptacles (45, 45A) on selectively adjustable depths and pressures for additional supply of a fluid mixture of a stream with a lower rate of underground fluids from the underground reservoir, which is otherwise possible with an uncontrolled multiphase flow.

In other embodiments, the effluent from the hydrocarbon or steam processing can be pumped axially downward, position (31) through the fountain fittings (10A) and into the subterranean formations through cracks, while the wastewater injection energy is used, for example, to operate the embodiments preferably a fluid-driven motor and pump (69 Figs. 26-29, 31-37 and 44-45). Alternatively, the fluid stream of a hydrocarbon gas or steam may, for example, be transmitted axially upward at a higher speed in a system of pipe columns (70, 76), from the space of a manifold or gas storage cavity, wherein the energy of a fluid with a higher gas expansion rate can be used to operate a fluid-driven motor and pump (69 Figs. 26-29, 31-37 and 44-45) to aid in pumping fluids or to assist in recovering substantially liquid fluid mixtures at lower speeds.

Other preferred embodiments of the pipe string system (70C Fig. 44, 76L Fig. 123) are applicable, for example, to accommodate proppant during fracture development and to flush to remove proppant after precipitation during fracture development using the connecting chamber sub (21) and channel selectors (47).

In other embodiments, implementation, systems (76L of FIG. 123) of pipe columns can be used, for example, to connect a plurality of horizontally and / or vertically close subterranean zones, before or after passing through one main shaft and wellhead equipment, for example, to create a plurality of wells extending from one main wellbore to increase the number of fracturing treatments using proppant, for example, shale gas deposits.

In the embodiments of the present invention, any combination of pipe columns (2, 2A, 2B, 39, 50, 51) can be used that can extend downward through one main shaft (6) from wellhead equipment (7), with a first pipe (71) a main trunk containing an inner pipe string (2, 39, 50) with a passage closest to the centerline (25, 53), and at least a second pipe (78) containing at least another pipe string (2A) , 2B, 2C, 39, 51). The other pipe string (2A, 2B, 2C, 39, 51) may be surrounded by a first annular passage (55) with one or more intermediate annular passages or concentric pipe passages (24, 24A, 24B, 54) located between the passage closest to the center line (25, 53) and the first annular passage (55) in the passage through the underground strata (52). Concentric pipes forming concentric passages or other pipes with passages can be connected by a distribution sub (23) to at least one radially extending or radial passage (75) and a connecting device (26) closest to the center line of the passage. The connecting device (26) closest to the center line of the passage can create a message between the upper passages (24, 24A, 24B, 25, 53, 54) and the lower passages (24, 24A, 24B, 25, 53, 54) formed by at least , one pipe string (2, 2A, 2B, 39, 50, 51) extending axially downward from the distribution sub (23) and formed from: the connecting chamber (43), the manifold (43A) of the connecting chamber, the intersection of wells (51A), the device (58) sludge passage, and / or a combination of distribution sub (23 and 23A-23Z) combined with the flow control element (61) and (elements), which can be used in combination for supplying a fluid mixture (38) to an underground well using simultaneously passing flows (31, 32, 33, 34, 35, 36, 36A, 37) of a fluid with different speeds, and / or from equipment (7) of the wellhead.

Embodiments of the pipe string system (49, 70, 76) may include a combination of devices taken from a group of flow control elements and configured to selectively control one or more fluid flows at varying speeds. The functions of pipe string systems of various embodiments may include selectively controlling one or more fluid flows at varying speeds to develop or produce fluid mixtures of liquids, gases, and / or solids that can be pumped into positions (31, 36), or removed from positions (34, 36A), one of the following: one or more zones near the underground passage (52) containing wells (17) in the formation and / or shafts equipped with shanks (3, 14, 15, 19), the storage space of the walls ( 1A) in the underground cavities, pore spaces of an underground formation or reservoir, fracture spaces of an underground formation or reservoir, or passage and / or processing spaces in pipe string systems or annular spaces. The flow of fluid mixtures (38) through the radial passage (75) of the distribution sub (23), between concentric pipe columns (2, 2A, 2B, 2C, 50, 51) and at least one pipe column (2, 2A, 2B , 2C, 39, 50, 51), can be controlled by at least one flow control element (61) installed between the pipes of the columns. Alternatively, the flow control element (61) can be installed through the passages (25, 26, 53) closest to the center line that communicate directly to the position (32) of the passages closest to the center line (24, 24A, 24B, 25, 26, 53 , 54, 55), or not directly, position (35) from the first concentric passage through another secondary concentric passage. In another alternative, the flow control elements (61) can be installed through the passages (25, 26, 53) closest to the centerline and communicating directly to the concentric passage (24, 24A, 54, 55) position (33) from the first pass, or not directly, position (37) from the secondary passage through the first passage. Concentric passages can be formed in and between concentric pipe columns (2, 2A, 2B, 2C, 39, 50, 51) and / or between the pipe column system and the passage through underground formations (52). The fluid communication can be controlled by the device of the column, distribution sub (23) and flow control elements (61), which can be made from a set of different elements for different configurations of one or more essentially hydrocarbon or essentially water wells formed from one main wellbore (6) and one equipment (7) of the wellhead or gushing (10, 10A) connected to the wellhead equipment.

DETAILED DESCRIPTION OF EMBODIMENTS

In a detailed discussion of selected embodiments of the present invention, it should be understood that the present invention is not limited to the specific embodiments described herein, and that the present invention can be practiced or implemented in various ways.

Figure 1-5 shows various configurations of conventional wells and systematic hydrodynamic functions, essentially for hydrocarbons and / or essentially for water-based fluid mixtures that can be injected into or extracted from the reservoir. Fluid mixtures can also be injected into an underground storage or spaces obtained after dissolving and washing out the salt or extracted from them using conventional single-stream systems in addition to simultaneously passing fluid flows and various well configurations.

Despite the use of a conventional device between hydrocarbon, water, and underground storage wells, the use of the simultaneous supply of fluids during dissolution and / or operation of an underground storage cavity finds very limited practical use.

An increase in demand and a decrease in the economic return and the magnitude of conventional discovery facilities increases the need to create new technologies that are applicable to increase hydrocarbon recovery from both conventional and unconventional reservoirs, such as tar sand and shale gas reservoirs. Innovations in the use of separately and simultaneously passing fluid flows at a variable speed to improve productivity, waste management and / or operation of underground storage facilities become more economically feasible for hydrocarbon production, which increases the applicability of the development of serial elements of well structures, production, injection and processing elements, as compatible kits, similar to building blocks combined in various devices, configurations and / or with different orientations to substantially improve the operation of such wells, as oil and gas, water, such as geothermal, waste wells, dissolving development and storage.

In addition, large-scale hydrocarbon reservoirs of tar sand and shale gas are currently considered unconventional sources, due to the difficulties of developing such reserves using current technologies. At the same time, embodiments of the present invention provide technologies for increasing heat transfer performance and developing cracks below one main trunk, reducing viscosity or increasing phase permeability of unconventional tar sand and shale gas reservoirs, which provides additional reasons for developing technology using serial equipment for simultaneous flow passage to transfer such stocks to ordinary stocks.

Figures 1 and 2 show longitudinal sectional diagrams of a conventional underground well that can be used for storage of hydrocarbons / water and development by dissolution, respectively. The figures show conventional flow control devices in addition to the flow control elements of a tubing string system kit containing equipment (7) wellheads and gushing (10) with ground valves (64) connected to casing strings (3, 14, 15) passing through the trunk into the strata (17), and together containing a passage through the underground strata (52). The pipe string system of the embodiment (70M of FIG. 1) may be formed by adapting the conventional well shown in the upper part of FIG. 1 and shown in the lower part of FIG. 1 in the form of a flow chart. The pipe string systems of the embodiments (70P of FIG. 1 and 70N of FIG. 2) may be formed by adapting the conventional wells of FIG. 1 and FIG. 2 with the addition of a flow control element (21 of FIG. 117-122). Similar completion of Figure 1 (2, 40, 61, 10) is usually used after removing the configuration of Figure 2 of development (1) by dissolving for underground storage in the walls of the salt cavern (1A).

If the state of the art for applications that include devices, since side-gate shafts (123), jet pumps (85), hydraulic fracturing couplings and gas lift valves, can form simultaneously passing fluid flows, applications of this technique in different wells types are limited; and impede the standardization of a set of devices and methods applicable to create options for the use of serial equipment, desirable for builders and operators of wells.

Embodiments of the present invention can be combined with conventional devices. For example, fountain fittings (10A of FIG. 2), a jet pump (85) and a concentric pipe (2A or 3), suitable for the simultaneous passage of fluid mixtures (38) and the circulation of water using a pump (116), are applicable for the formation of options (70M) of the implementation of FIG. 1 or of the embodiment (70N) of FIG. 2, together with the addition of an embodiment of a distribution sub (21) of the connecting chamber to the well.

In general, for hydrocarbon, water, and storage wells shown in FIGS. 1 and 2, flows of approximately the same speed occur using columns with one channel and / or completion equipment of approximately the same internal diameter, contributing to the overall flow rates passing through the closest to the center line of the passage (25) of the tubing string (2), regulated by an underground valve (74) in case of risk of underground pressure manifestations, as shown in FIG.

Figure 1 shows an underground valve (74) and a packer (40), flow control elements (61) regulating adjacent concentric passages (24, 54) with a gate (123) of the side openings or a jet pump (85) regulating the communication between passages (24, 54) and shoes (16) of the casing string. Monitoring of isolated annular spaces can be carried out with measuring instruments (13) of annular spaces, confirming the tightness of the well, measurements in a fluid mixture (38) entering or leaving the tubing at the lower end of the well and exiting, position (34) or pumped, position (31) to gushing (10) at the upper end of the well. Concentric passages (54) are generally not designed for a continuous flow of produced or injected fluids, except in special cases, such as using a gate (123) side openings to change annular fluids, supply water to a jet pump (85), or in the cases described below and shown in Fig.40-41 and 46-47.

In a conventional well configuration using the jet pump of FIG. 1, use is made of the annular space between the tubing (2) and the last casing (3) with cementing to supply water for the venturi pipe (85) (referred to as the jet pump) installed in tubing. When using a conventional jet pump, the practical value of this approach can be limited, since the water combined with the flow of the resulting fluid mixture (38) must then be removed. At the same time, the illustrated embodiments (70M, 70P) give separate flow rates in individual flow applications, such as in a selectively adjustable length high-speed lifting column, and / or form many separate flows, for example, in jet pump and downhole processing applications.

Embodiments of the present invention include, for example, the use of a jet pump forming separate, simultaneously passing fluid flows at a varying rate to stimulate production. For example, an embodiment (70M) of a pipe string system shown in the lower part of FIG. 1 is made using the last casing string (3) with cementing and fountain fittings (10) of FIG. 1, or fountain fittings (10A) of FIG. 2 and the corresponding equipment (7) of the wellhead, for inclusion in the composition of the concentric tubing string (2A) between the tubing (2) and the last casing string (3) with cementing. In this case, a circulation path is formed between the concentric pipe string (2A) or the last casing string (3) with cementing and the internal string (2), to form a closed system with a pump (116) with a high-speed flow and continuous circulation connected through the pipe ( 85) Venturi, with tubing (2). Part of the production is taken from the tubing (2) to create a vacuum effect of the venturi to reduce the hydrostatic pressure in the first stream of the produced fluid mixture to further stimulate its production (34), while the second water stream obtained using the pump (116) , is fed into the tank of the circulation system and separated in it. In the circulation tank, part of the second mixture fluid stream is separated into a liquid stream (119), which is drawn between the water contact (117) and the liquid contact (118). In addition, the gas stream (120) can be sampled at the upper end of the circulation tank. The circulation fluid can be reused or replaced, the circulation fluid is usually treated with water, other mixtures of liquids, gases and / or solids if necessary.

Traditionally, jet pumps, in general, are used in applications in collectors with water flooding or water displacement with high water cut rates, while water supply facilities limit their use. However, embodiments of the present invention may include evacuating the hydrocarbon portion of the production using devices such as a venturi, so that the subsequent separation of the fluids in the circulation tank should be generally small, as well as the effect of restrictions from the water supply facilities .

The arrangement of the device of Figure 1 can also be used for underground storage wells, while the shoe (16) of the last casing string (3) with cementing can be an element of flow control for products stored in the walls (1A) of the cavity. An embodiment (70P) of the implementation of the pipe string system can be accomplished by adding an adapter (21) of the connecting chamber and the corresponding pipe (2, 2A), which can be used for selective access and passage of separate, simultaneous fluid flows from gravitationally separated products, such as untreated oil and liquefied natural gas (LNG) floating above oil and brine in the walls of the salt cavern (1A). Separate and simultaneous flows can be used to selectively displace gravitationally separated products in a cavity by using a selective installation of a channel selector in a selected sub (21) from a connecting chamber of the same depth as the selected product separated by gravity.

As shown in FIG. 2, conventional dissolution development configurations cannot perform the function of an underground manifold to selectively control simultaneously flowing fluid flows, since the leaching column (2) closest to the centerline is freely suspended in the outer leach column (2A) without radial passage of the sub or Possibilities of selective direction and / or redirection of flows. Simultaneously passing flows for the shown conventional configuration consist of flows of injection (31) of water and extraction (34) of brine, while injection (31) or extraction (34) can pass through the passage (25) of the column (2) closest to the center line opposite flow orientations in the concentric passage (24), or vice versa. The leach buffer or coating of hydrocarbons or inert gases, such as nitrogen or diesel fuel, is generally communicated through the first annular passage (55) to control the dissolution of the salt in an axially upward direction.

In typical applications, simultaneously passing streams in the space of an underground cavity developed by the solution using the salt dissolution process are limited to injecting (31) a buffer fluid inert to salt and water with extraction (34) of brine from the salt and from the passage closest to the center line ( 25) and a concentric passage (24, 54). The passage of the flow into the passage (25) closest to the center line from the concentric passage (24), and vice versa, is impossible without first passing through the first annular passage (55).

The state of the art does not provide communication between concentric passages (24, 25) without first entering the first annular passage, and only the depth of the column closest to the center line (2) can be adjusted using a heavy-duty drilling rig required to remove and rearrange both pipe columns ( 2, 2A) to change the depth of the water outlet and the inlet of the brine. On the contrary, the embodiment (70N) of the implementation of a system of pipe columns with one or more distribution sub (for example, 21 Fig. 117-122) may be applicable for selectively controlling simultaneously passing fluid flows between the closest to the center line and concentric passages, using the installation twin packers and plugs for isolating and diverting fluid through one or more radial passages without cutting or removing pipe columns using a heavy-duty drilling rig.

After development by dissolution of the well, completion equipment (2, 40, 74, and 10 of Figure 1) can be installed to form an underground storage well through the last casing (3) with cementing, after removing the twin strings (2 and 2A) used to enlarge spaces in the walls of the cavity (dashed lines 1A of FIGS. 1 and 2) using the salt dissolution process. This salt dissolution process involves the use of leaching fountains (10A) to leach (31) water to produce (34) an essentially aqueous salt solution containing liquid water and solid salt dissolved in a fluid mixture (38) to increase the space in the walls (1A) of the cavity formed in the deposits (5) of salt located in underground zones. Option (70N) of the implementation of a system of pipe columns with freely suspended pipe columns (2, 2A) connected to the adapters (21) of the connecting chamber can be used to eliminate the need to remove the external leaching column to control the development of dissolution. Fountain fittings (10A) with the corresponding equipment (7) of the wellhead, which can carry concentric pipe columns (2, 2A), together with the distributor sub (21) of the connecting chamber, can be used to access products with different relative densities stored in the cavity and naturally separated by gravity, where a pipe string system (70P of FIG. 1) with an operational packer (40 of FIG. 1) and an underground valve (74 of FIG. 1) replaces the conventional dissolution configuration or system (70N) of pipe columns.

Figure 3 shows a conventional cable lift (4A) that can be used to selectively install flow control elements to change the configuration of a pipe string system, or physically change the configuration of a pipe string system using rotary cable tools. Rotary cable instruments can be lowered, for example, through fountain fittings (10) and wellhead equipment (7) for installation in the passage closest to the center line or connecting device of the pipe string system closest to the center line. In addition, FIG. 3 shows a closing ground shutter (64) connected to a blowout preventer (9) and a lubricator (8) that can be detached to install flow control elements in the lubricator. Then, the gate valves can be opened when the wire or cable (11) passing through the pressurized stuffing box or the head of the grease gun at the upper end of the lubricator provides sealing when lowering or lifting (12) the winch flow control devices for installation in passages through underground formations (52 Figure 1-2).

A drilling rig (4) of any kind, which is, for example, a rig with a flexible tubing or a rig using continuous or composite casing, is suitable for lowering flow control elements into a pipe string system. During well construction, when, for example, a pipe arrangement (49 Fig. 100-105) of pressure-controlled pipes functions as a pipe string system installed with a passage through a blowout preventer of a drilling rig, this can be used to control the first annular passage (55 Fig. .1-2) before connecting the pipe string system to the equipment (7) of the wellhead, for controlling annular passages (24, 24A of Figs. 1-2), using a ground gate tree (64), which is installed later for controlling internal passages and connection with t VAVO rig (4A). A fluid mixture called a drilling fluid may pass through the riser of the drilling rig to the wellhead funnel where the circulating drilling fluid returns after passing through the drill string and blowout preventer of the drilling rig. A drilling rig outlet can perform, similarly to a stuffing box, a fluid control function if the drilling fluid cannot balance the underground pressure. Similar to a cable lift (4A), a drilling rig (4) can be used to install a pipe string system or a flow control device using a drawworks to lift (12) a cable (11) passing through the tower block to be installed in a passage located in underground strata (52). The pipe string system can be used to selectively control a fluid mixture of drilling fluid, cement and fracturing fluids with proppant and solid particles or other working fluid mixtures that simultaneously pass through the passage and the concentric passage closest to the center line.

Embodiments of the present invention provide at least one straight sub passing through a radial passage between the passage closest to the center line (25) and one of the concentric passages (24, 24A, 54), with a first passage through an adjacent concentric passage (24, 24A, 54) or the first annular passage (55) or without it, while the flow control element selectively affects the fluid communication through the radial passage using, for example, fountain fittings (10A) or a riser manifold to act on fluid velocity and corresponding pressure in one or more passes (24, 25). This selective control of the speeds and corresponding pressures in the passages can be used, for example, to build wells and / or to stimulate production similar to a high-speed lifting column or underground treatment, to separate hydrocarbon gas so that such gas can be used for gas lift in one or more remaining passages essentially a fluid stream at selected depths and at selected pressures, thereby further increasing production.

Figure 4 shows a graph of an example of relationships in a known high-speed lifting column, giving the dependence of the pressure in the flow at the bottom of the inflow in the graph of the methodological function for the flow of hydrocarbons. Downhole pressure increases upward along the vertical axis of the graph, and inflow increases to the right along the horizontal axis of the graph. During the life cycle of the hydrocarbon reservoir, the pressure function (F1, F2, F3), that is, the dependence of the inflow on the bottomhole pressure in the flow, decreases from F1 to F3 with a decrease in pressure in the reservoir. The diameter of the production string (2 of FIG. 1) affects the speed and the corresponding frictional resistance and pressure, determining where the minimum inflow (P1, P4) without assistance takes place, which can be compared with the critical inflow (P2, P3) corresponding to the gas saturation point in a hydrocarbon fluid mixture described by functions F4 and F5.

At the beginning of well construction, a cost-effective decision to install a larger diameter string (F5) and a smaller diameter high-speed lifting string (F4) should be made by comparing the initial inflow (FR1) and the final inflow (FR3) of the larger diameter string with a lower initial inflow ( F2) and a higher inflow (F4) of the high-speed lifting column, relative to a decrease in reservoir pressure as a result of reservoir depletion and natural inflow.

Since the economics of replacing a larger diameter production string (F5) with a smaller diameter production string (F4) for depleted reservoirs is often unfavorable, lower larger column flows (FR3) may be acceptable compared to higher potential flows (FR4) of a high-speed lifting string.

Pipe string systems applicable within the scope of the present invention can provide a means to follow tributaries FR1 to FR2 with a large diameter column, followed by a geotechnical activity on a cable lift (4A of FIG. 3) to selectively install flow control elements to adjust the working diameter of the production string with the influx of FR5 by diverting all or part of the production through one or more distribution sub. Through a repeated geotechnical activity on a cable lift, the function of a high-speed lifting string between F5 and F4 can be followed to produce hydrocarbons with higher flow rates without having to remove the production string.

Figure 5 shows an example of a functional graph explaining the dependence of the pressure of a hydrocarbon liquid, a gas phase on temperature. The graph shows the pressure increasing upward along the vertical axis and the temperature increasing rightward along the horizontal axis. The graph of FIG. 5 includes curve 1 of the function (F6) of the saturation points of the liquid fluid mixture and curve 2 of the function (F7) of the saturation points of the gaseous fluid mixture (F7) intersecting the vertical constant temperature line at point C. Curve 1 of the function (F6) of the points saturation indicates that outside the region of the curve of the saturation points above the critical point there is a completely liquid fluid mixture, and below the critical point outside the region of the curve of the saturation points, there is a completely gaseous fluid mixture. However, in the curve of saturation points there is a fluid mixture of liquid and gas. Functions F8, F9, and F10 show fluid mixtures with 25 percent, 50 percent, and 75 percent liquid, respectively.

During operation, when reducing the pressure acting on the collector from A1 to A2, by opening the gate valve (64 Fig. 1) of the fountain armature (10 of Fig. 1) on the surface, a completely liquid underground hydrocarbon fluid mixture passes into a fluid mixture of liquid and gas into point A2. If it is possible to maintain the temperature during production through a colder underground reservoir above the reservoir, the percentage of fluid should be reduced to 75% at point B of function F10.

When hydrocarbons are passed through a surface separator, the fluid mixture can be separated, for example, into 75% of the liquid at pressure and temperature point S2. If the temperature drop due to operation can be minimized to a higher pressure point S1 using the underground separation process using heat in the subterranean formations, a higher inflow for the same fluid mixture with 75% liquid can be achieved. On curve 2, the functions of the saturation points for a fluid mixture in which there is more gas, an increase in pressure from S4 to S3 is more noticeable, thus the result is relatively higher inflows when underground separation of the fluid is used to maintain the temperature.

As described, since the resulting inflow is not only a function of pressure and temperature, but also the depletion of the reservoir and the diameter of the production string, options for more targeted control of feed rates, pressures and temperatures in the pipe string system are implemented to better control the inflows during the life cycle wells, and include the best regulation of thermal factors affecting the provision of uninterrupted supply when performing underground processing of the fluid.

In addition, the pipe string system applicable to create underground separation can also be used to control simultaneously flowing fluid streams using a gas lift, an essentially liquid stream with a selectively controlled and essentially gaseous stream, using gas lift valves between the two streams to further facilitate mining using underground processing.

On figa example of the prior art shows a graph of the function of the dependence of pressure at the point of contact with the hydrocarbon reservoir from mass influx. The figure shows the increase in pressure up the vertical axis and the increase in mass flow to the right on the horizontal axis. Function F11 is a function of saturation points, function F12, passing from point P5, represents a decrease in pressure exerted on the contact surface in the manifold when opening the fountain fittings and feeding with the flow measured by the mass of the passing mixture.

The feed function F13 provides a theoretical example of the possibility of a stable supply of hydrocarbon at pressure and inflow of point P6, which becomes unstable at pressure and inflow of point P7. After that, the figure shows that stable supply cannot be achieved until the pressure and inflow of point P8 are reached.

As is often the case in practice, the pressure exerted at the site of contact with the reservoir at the opening of the well is critical for a stable flow of production and some inflows may work better than others. Therefore, the practical feasibility of selectively changing the flow configuration in the production string during hydrocarbon production during the life cycle of a well is valuable because flow rates, pressures, and temperatures change with reservoir depletion.

Known production methods generally focus on device combinations for a single stream and relatively static configurations for subterranean separation, ignoring the dynamic nature of the subterranean fluid stream with varying velocities, pressures and temperatures over the life of the well, as safety and / or economic factors generally exclude changes in the production casing after installation.

Through the use of a combination kit of compositional components, the pipe string system of embodiments of the present invention can be used to selectively control flow during the life cycle of a well with flow control elements installed between concentric pipe pipes and / or through the passage closest to the center line, taking into account theoretical production functions or injection for essentially water or essentially hydrocarbon wells, such as those described above and shown in FIGS. 4 and 5. o, embodiments comprising pipe column systems applicable to flow control devices installed between concentric column pipes and / or through an aisle closest to the center line, allow those skilled in the art to access through an aisle closest to the center line and / or removing additional flow control elements that can selectively control a real nonlinear production function, such as that described above and shown in FIG. 5A, for life well cycle, without safety or economic impacts associated with replacement of production casing.

Figures 6-7, 8-16, 17-20, 21, and 22-37 show a system of pipe columns and adapters, applicable to change the effective diameter and, thus, the speed for a given stream along the length of the system of pipe columns.

Elements of a system of tubular columns, for example, with the sub (23) of the concentric pipe of Figs. 8-16 are connected in series or in parallel above or below other distribution sub (23) of the Figs. This connection can be used alone or in combination, for example, with an adapted connecting chamber (43) of FIG. 21, while various flow control elements (61) of FIGS. 22-37 can be connected to one or more receiving sockets (45), and can additionally be combined with other elements of the kit of a system of pipe columns in any combination or device with interlocking passages for selectively controlling a plurality of simultaneously passing flows of fluid mixtures, essentially hydrocarbon and / or essentially water.

Figures 6 and 7 show a longitudinal section and a flow chart, respectively, of an embodiment (70A) of an implementation of a pipe string system (70) applicable as a selectively variable length lifting column. The Figure shows an inner concentric pipe string (2) and an external concentric pipe string (2A) connected to equipment (7) of the wellhead and fountain fittings (10). A number of distribution sub (23, 23A, 23B of Figs. 8-9, 23C of Fig. 10, and 23Y of Fig. 14) is used to reduce the effective diameter to form a high-speed lifting column, as described above and shown in Fig. 4, using a lead at least part of the flowing fluid flow, which passes at the position (32, 35) of the passageway (25) closest to the centerline or at the position (33, 37) of the adjacent concentric passage (24), for the friction equivalent of the velocity diameter to the length of the stream using a selective installation of control elements sweat ok. The uppermost distribution sub (23A) can eliminate the use of a concentric passage (24), providing flow rate control with a valve (74). Fig. 7 shows a valve (74), such as a safety valve, operating with a control line (79) and gushing (10), to create selective control of pressure in the well for controlled production from the well.

The distribution sub (23A) of the high-speed lifting column can be formed by the distribution sub of Figs. Alternatively, an equivalent distribution sub (23A) can be formed by blocking only the throttle holes (59 of FIG. 13) below the receptacle (45 of FIG. 13) in the distribution sub (23C of FIG. 13).

Fig. 8 is a plan view with line AA corresponding to the section of embodiment (23B) of the distribution sub (23) shown in Fig. 9, in which the entire flow of the passage (25) closest to the center line can be diverted through the radial passage (75 Fig. .9) in the concentric passage (24), if the blocking device is installed in the receiving socket (45 of Fig. 9). At the same time, only a part of the flow of the concentric passage (24) can be connected with the passage closest to the center line, since through passages are created. These through passages are permanently blocked in the distribution sub (23A) of FIGS. 6-7.

The distribution sub of the distribution element of this configuration is applicable, in a potentially inverted orientation relative to that shown in FIG. 9, at the lower end of the space of the hydrocarbon fluid separation element to allow the movement of heavier fluids into the passage with reduced frictional resistance and increased effective diameter, while lighter and more gaseous fluid flows are more easily compressed and move through the passage with higher friction, while two fittings for simultaneously passing the flow of the mixture fluid at different velocities.

Fig. 9 shows a distribution sub (23B) of Fig. 8 in longitudinal section along line A-A. The figure shows portions of a concentric passage (24) blocked by the wall (75A, shown in FIGS. 8 and 9) of the radial passage (75), fluid communication between the passage (25) closest to the center line and the concentric passage (24), i.e. between the column (2) closest to the center line and the adjacent concentric pipe column (2A) with ends (90) connected to other pipes of the pipe column system. The sub can be oriented, as shown, or rotated, while the radial passage tilts down and in instead of tilting up and in.

Fluid mixtures can be injected (31) or produced (34) through any passage (24, 25) depending on the connected flow control element. If, for example, a twin packer (22 of Fig. 93A) is connected to a receiving receptacle (45) to block the throttle holes (59) of the radial passage (75), unidirectional or axially opposite flow orientations between the passage flows can be used for well operation. If the nozzle controls the throttle holes (59) of the radial passage (75) to connect only part of the flow (32, 33) through any of the passages (24, 25), then various other feeding devices, including, for example, separation devices and / or gas lift can be selectively performed by installing multiple distribution sub (23B) followed by selectively installing twin packers and fittings to form a fluid flow pattern.

The distribution sub (23B) is similar to the distribution sub (23) with a throttle hole at the lower end of the sub (21) of the connecting chamber of Figs. 117 and 119-122, while the radial passage wall (75A) is better suited for higher erosion speeds.

10 and 12 are plan views with lines B-B and C-C of respective sections shown in FIGS. 11 and 13, respectively, of an embodiment (23C) of a distribution sub (23). The Figures show a section line (BB) passing through a concentric passage (24) and another section line (CC) passing through a wall (75A) of a radial passage (75) located between the inner concentric casing pipe (2) and the outer concentric casing pipe (2A).

11 and 13, longitudinal sections are shown along lines B-B and C-C of FIGS. 10 and 12, respectively, of a distribution sub (23C). The figures show an embodiment where two streams can be separated, crossed or connected depending on the flow control element connected to the receiving socket (45). The injection (31) or extraction (34) of the fluid mixture can pass either through the passage closest to the center line (25) or through an adjacent concentric passage (24) between the pipes (2, 2A) with the ends (90) connecting to the other pipes of the pipe system columns, while the flows above and / or below the receiving socket (45) can cross, passing through a radial passage (75). Various flow management options using various flow control elements connected in a given distribution sub (23C) are shown in FIGS. 22-29.

An exemplary device of the connected flow control element includes the use of a dual packer to block throttle openings (59) above or below the receptacle (45) to block a concentric passage (24) below or above the receptacle (45), respectively, wherein the opposite the concentric passage (24) is connected to the passage (25) closest to the center line. Other examples of devices for connected flow control elements include blocking throttle openings (59), both above and below the receptacle (45), with a dual packer to block the concentric passage (24), while ensuring flow passage in the closest to the axial the passage line (25) through the channel of the twin packer, or by installing a blocking element for regulating the flow connected to the receiving socket (45) in the passage closest to the center line to cross the flows between the closest to the center line Odom (25) and a concentric passage (24) as described below and shown in Fig.22-25.

The distribution sub (23C), Figs. 10-13, complements the sub (21) of the connecting chamber, Figs. 117 and 119-122, making it possible to block the entire flow or divert part of the flow that can communicate through a concentric passage (24). The sub (21 of Figs. 117 and 119-122) of the connecting chamber can only discharge into a concentric passage. The serial connection of the data of two distribution substs (21 and 23C) allows selective blocking of the closest passage to the center line (25) and the concentric passage (24) or one to the other.

Distribution Sub (23C) of Figs. 10-13 also complements the Distribution Sub (23Y) of Figs. 14-16, connected axially above or axially below the shown distribution sub (23C), making it possible to block the entire flow or divert part of the flow communicating via concentric passage (24) with the passage (25) closest to the center line. The distribution sub (23Y of FIGS. 14-16) can be used to block the entire flow or divert part of the flow communicating through a concentric passage (24) with another concentric passage (24A) and / or the passage closest to the center line (25). The serial connection of the data of two distribution sub (23C and 23Y) with an additional pipe string (2B) installed near position 23C enables selective blocking or removal of multiple concentric passages (24, 24A of Fig. 14).

On Fig and 15 in an isometric view with magnification, with the part highlighting line D and the part highlighting line D, respectively, with dashed lines showing invisible surfaces in Fig. 15, a distribution sub (23) or an embodiment (23Y) of a sludge passage device (58), which may correspond to FIG. In embodiments, the figures show an adapter similar to that shown in FIGS. 11-13, the dashed line represents an additional concentric pipe (2B or 51) or a passage through underground formations (52), with an additional passage (24A) of the concentric pipe, if the additional pipe ( 2B or 51) is present, or with the first annular passage (55) if there is no additional pipe (2B, 51) represented by dashed lines.

The throttle openings (59) of the radial passage (75) can be located in the passage (25, 53) closest to the center line formed by the inner pipe string (2, 50). The elements can be positioned similarly to the distribution sub (23C) of FIGS. 10-13, except that an additional wall (82) can be installed within every second wall (75A) of the radial passage (75), with a corresponding throttle hole (59A) of the concentric pipe (2A). Each second radial passage can create a fluid communication between the concentric passage (24, 54) or an additional concentric passage (24A, 55) and the passage closest to the center line (25, 53). The device of radial passages (75) between the passages (24, 24A, 25, 53, 54, 55) and the passage closest to the axial line (25, 53) is similar to the distribution distributors (21) of the connecting chamber of Figs. 117 and 119-122 or the device (58) the passage of the sludge, in that the radial passage (75) passes through an adjacent concentric passage (24, 54) to connect the passage closest to the centerline (25, 53) directly to a non-adjacent concentric passage (24A, 55).

On Fig shows an isometric view corresponding to the distribution sub (23Y) 11-15. The Figure shows a device without external concentric columns (2A, 2B of Fig. 15) for demonstrating a radial passage device, where every second passage creates a message between the passage (25, 53) closest to the center line and the adjacent passage (24, 54 of Fig. 14- fifteen). The remaining radial passages (75) can be diverted by an additional wall (82) into the throttle hole (59A Fig. 14-15) in the adjacent outer wall (2A Fig. 14-15), to form a direct passage between the passage closest to the axial line (25, 53) and the first annular passage (55 Fig. 14-15) or an additional concentric passage (24A, 54 Fig. 14-15) with the outer wall of the receiving socket (45) protruding into the concentric passage (24, 54 Fig. 14-15) but not blocking it.

On Fig, 18 and 19: shows a plan, side view and isometric view, respectively, associated with Fig, dashed lines show the invisible surface of the option (23D) implementation of the distribution sub (23). The distribution sub can be used with the adapted connecting chamber of Figs. 20 and 21. The figures show the connecting devices (26) of the passage closest to the center line connecting between, for example, the pipes (39 of Figs. 20-21) of the output channels and the pipes extending closest to the center line passage (25 Fig.20-21) of each channel exit pipe. The figures include two radial passages (75), between the left connecting device (26) of the passage closest to the center line, which can create fluid communication with two throttle openings (59) of the distribution sub (23D) connecting to the throttle openings (59B of FIG. .20) a concentric passage (24 of FIG. 20) located between the inner concentric casing (2 of FIG. 20) and the outer concentric casing (2A of FIG. 20). An example of a similar device is shown in Fig. 82.

Twin packers can be installed across one or both radial passages (75) to prevent radial flow. Alternatively, the plug can be installed in the connecting device (26) of the left passage closest to the center line to supply flow to the radial passage. The throttle openings (59) can be connected with one concentric passage (24 or 24A of Fig. 15 and 20) or with different concentric passages (24 and 24A of Fig. 15 and 20) to ensure simultaneous passage of the flow at the position (32, 35) closest to the axial passage lines (26 and 25 of Figs. 19-21) or at the position (33, 37) of the concentric passage (24, 24A of Figs. 15 and 20) for injection or production either through passages closest to the center line or through concentric passages.

On Fig and 21 shows a plan and isometric views of the adapted connecting chamber (43), applicable for the formation of a distribution sub (23) when combined, for example, with a distribution sub (23D) Fig.17-19. The Figures show the inner concentric pipe column (2) in the outer concentric column (2A), forming a wall (41) of the chamber and an additional one pipe (78) of the main channel with throttle openings (59B) in the bottom (42) of the connecting chamber, for communication fluid concentric passage medium (24). Other concentric pipes (2B shown by a dashed line) and other throttling openings (59C) can be added to create fluid communication with one or more throttling openings (e.g. 59 Fig. 17-19) or a concentric pipe string (e.g. 2, 2A and 2B FIGS. 14 and 15) of a distribution sub (23).

On Fig and 24 shows plans with lines B-B and C-C of sections 23 and 25, respectively, of a variant (70J) of the implementation of the system (70) of pipe columns. The Figures show systems (70) of pipe columns of embodiment (70J) with a distribution sub (23C Figs. 10-13 or 23Y Figs. 14-16) and a flow control element (61), shown as an example, a blocking plug (25A) installed in the receiving socket (45 Fig.23 and 25). The Figures show an inner concentric pipe string (2 Figs. 23 and 25) and an external concentric pipe string (2A of Figs 23 and 25) forming a concentric passage (24) from which the radial passage can be diverted by the walls (75A) into the throttle openings in the passage closest to the center line (25 of Figs. 23 and 25).

23 and 25 show longitudinal sections along lines B-B and C-C of FIGS. 22 and 24, respectively. The figures show a system (70J) of pipe columns with blocking or plug (25A), a flow control element (61) connected to a receiving socket (45) using spindle connecting devices (89) installed in a distribution sub (23C) of FIG. 22 and 24. The ends (90) of the pipe string system (70J) are connected to other elements of the pipe string system. The plug (25A) can be installed through the passage (25) closest to the center line using a cable hoist (4A of FIG. 3) on the cable (11 of FIG. 3) and connected to a connecting device (68) for lowering (12 of FIG. 3) into passage through underground formations (52 Figures 1 and 2) or ascent from them. After installing or removing the plug (25A), the cable connection to the connecting device (68) can be disconnected.

The closest passageway (25) closest to the center line of the inner concentric pipe string (2) can be blocked by a plug (25A), allowing the transfer of injection (31) or production (34) from the closest concentric passage to position (25) closest to the centerline of the passage (25). (24) or from an adjacent concentric passage to position (32) of the passage closest to the center line through radial passages (75).

Crossing of flows between the passage closest to the center line and the concentric passage can be used, for example, to form the preferred embodiment (23F) of the shutter of the distribution sub of Figs. 42 and 44-45. In this embodiment, the underground valve (74 Figs. 42 and 44-45) can be installed at one end of the distribution sub (23C) with a plug (25A) installed to allow selective control of each flow by the underground valves, while creating access through the passage (25) closest to the center line when the plug is removed. The underground valve can be controlled independently, in applications, if a separate selective control is required, or managed together if, for example, the underground valve is an underground safety valve with guaranteed closure in an emergency.

Alternatively, a flow sub with a flow control element (61) which is, for example, a fitting or a pressure-controlled valve or a single-acting valve installed in the inlet socket (45) instead of the plug (25A), can create a space in the passages for changing the flow rate and the corresponding pressure at various underground depths. The temperature of the formation can be taken into account when selectively changing the configuration of the underground processing space, for example, to separate fluids and / or a gas lift of a substantially liquid stream, allowing a portion of the transferred gas stream to enter substantially the liquid transferred stream under the flow control element, without the need for conventional side gas lift mandrels and gas lift valves, access to which in practice is often more difficult than to a valve installed in a receptacle with a nipple profile, pop A cross of the element closest to the center line of the passage.

Alternatively, if the pipe string system (70J) adapted with the sub (23Y) of FIGS. 14-16 is used instead of the distribution sub (23C) shown in FIGS. 22-25, the flow can be selectively directed to the position (35) closest to the centerline a passage (25) from a non-adjacent concentric passage (24A or 55 of Figs. 14 and 16), or selectively direct to position (37) of a non-adjacent concentric passage (24A or 55 of Figs. 14 and 16) through a passage (25) closest to the center line )

26-39 show devices for performing rotary operations applicable to other rotor cable devices and methods in the pipes of the pipe system (70 and 76 of Fig. 50) during the life cycle of an underground well. The figures include a connecting to the cable (11 Figure 3), a device (61) for regulating the flow in the form of a borehole assembly (69) of the engine and / or pump, with the possibility of installation, suspension and removal on the cable, a lift (4A of Figure 3) . The figures further include an electric motor (111) or a hydraulic motor using, for example, turbines, impellers or rotors and stators, with fluid inlets and outlets (59) associated with a radial passage (75) located in the distribution sub (23), for directing the first flow of a fluid mixture to act on a hydraulic motor that can operate due to a pressure or fluid differential to the flow rate of expanding or compressed gases to pump a second flow of a fluid mixture.

Since the energy in any system is saved, not created and does not disappear, the use of a pipe column system for selectively installing a flow control device in separate flows of varying speed is possible to provide technical personnel with a means to control the distribution of energy from the first, flowing fluid mixture to the second simultaneous flow, for better distribution of energy in the system during operation.

FIGS. 26 and 28 show plans with BB and CC lines of sections of FIGS. 27 and 29, respectively, and an embodiment (70K) of an implementation of a system (70) of pipe columns with a distribution sub (23C of FIGS. 10-13, 23Y of FIG. 14 -16) and concentric pipe columns (2, 2A) around the embodiment (69 A) of the fluid control element (61 of Figs. 27 and 29) with a hydraulic motor and pump (69 of Figs. 27 and 29). The figures show a device suitable for pumping a fluid through a passage using a pressure head and the pressure of the passing fluids or expanding the gas of the first stream to pump the second stream.

FIGS. 27 and 29 show longitudinal sections along lines B-B and C-C of FIGS. 26 and 28, respectively. The figures show the arrangement of a pipe string system (70K) with a flow control element (61) with an engine and a fluid pump (69A) connected to a receptacle (45) by a connection (89) to a sub (23C or 23Y). The Figure shows the inner concentric pipe string (2) and the outer concentric pipe string (2A) forming a concentric passage (24) and the passage closest to the center line (25), applicable for installing and operating the flow control element (61) using the connection ( 68) and a cable lift (4A of FIG. 3). The ends (90) of the pipe string system can be connected to other elements of the pipe string system (70) to supply a flow of a first simultaneously supplied fluid mixture, which can be used to operate a hydraulic motor to pump a second, simultaneously supplied fluid mixture of varying speed.

The internal components of the hydraulic motor and fluid pump (69) are similar to those shown in Figs. 36-37, where the shaft connects two fluid-rotated devices (112), for example, a turbine or an impeller, which can be adapted to be actuated by a fluid and pumping the fluid of two separate simultaneously passing streams of fluid mixtures. For example, a fluid injected by position (31) at position (32 and 35) of the passageway (25) closest to the center line, through the radial passage (75) from the concentric passageway (24 and 24A of Figures 14-15, respectively) below the sub ( 23C, 23 Y), can drive a rotating turbine (112) connected by a shaft to another turbine (112), which can be used to transfer the produced fluid position (34) to the position (32 and 35) of the passage closest to the center line ( 25) through the radial passage (75) from the concentric passage (24 and 24A of Figs. 14-15, respectively) above the sub (23C, 23Y). As an alternative example, the fluid obtained at (34) through the passages due to the natural expansion and / or underground pressure of the stored compressed gas or gas-saturated fluid, at (33, 37) of the concentric passage (24A, 24) passing through the radial the passage (75) from the passage (25) closest to the center line below the sub (23C, 23 Y) can rotate the turbine (112). A rotary turbine (112) can rotate a shaft connected to another turbine (112) and can be used to pump, for example, a substantially liquid obtained fluid position (34) as a result of underground separation or, for example, a substantially aqueous fluid mixture, injection position (31) into the nearest passage through the underground formation. Essentially, an aqueous fluid can be used for dissolution or disposal development between the passage (25) closest to the centerline and the concentric passage (24, 24A) through the radial passage (75).

On Fig shows a plan view with a line F-F of the cross section of Fig.31 and the line G of the selection of parts, respectively, Fig.35. The figure shows a variant (70G) of the implementation of a system of pipe columns with a variant (69B) of the implementation of the element (61 Fig.35) flow control with an engine and pump (69 Fig.31) fluid installed in the variant (23E Fig.31) implementation of the distribution sub (23).

On Fig and 34 shows a longitudinal section and isometric view, respectively, along the line F-F Fig.30. The detail lines H and I in FIG. 31 relate to the parts in FIGS. 32 and 33, respectively, and the break line in FIG. 31 corresponds to the break in FIG. 34. On Fig shows a longitudinal section of a section of concentric pipes removed from the system (70G) of pipe columns, potentially passing to the connection with the equipment of the wellhead and / or gushing at the upper ends (90), as shown in Fig. 31. FIGS. 31 and 34 show an engine and a fluid pump (69B) mounted with a cable connection device (68) and connected to a receptacle (45 of FIG. 32) of a sub (23E) by a connection device (89 of FIG. 32). The lower ends (90) of the inner concentric pipe string (2) and the outer concentric pipe string (2A) are shown connected to other pipes in the passage through the subterranean formations (52 of FIGS. 42 and 44) for the vertical separation of subterranean close zones. This separation of the underground zones can be performed using, for example, an adapter (21 of FIG. 117 and 119-122) of the connecting chamber and / or transversely divided zones using, for example, access of a distribution adapter (23T of FIG. 83-87) of the connecting chamber through pipe (39 Fig. 83-87) of the output channel. This separation can be used when, for various reasons, it is necessary to maintain a simultaneous supply of fluid flows in one passage, above and below the distribution sub (23E).

In the embodiment (23E) of the implementation of the distribution sub, the fluids of the mixture of liquids, gases and / or solid particles can be injected, position (31) or produced, position (34) through the passages (24, 25), thereby creating a fluid communication through radial passages (75) and throttle openings (59), from the passage (24, 25) to actuate any rotating device (112), and return the flow to the descending closest to the center line and concentric passage. Rotary devices (112) are shown, for example, as a hydraulic motor and a fluid pump (69B).

FIG. 32 shows, with increasing magnification, the portion of the connection (45 and 89) of the engine receiving receptacle and the fluid pump (69B), within line H of the part of FIG. 31. The figure shows the discharge passage, position (31) and extraction, position (34) through the radial passage (75). The flow control elements (61) with a seal (66) are designed to hold the pressure of one flow of a fluid mixture from being connected to another.

33 is an enlarged view of a distribution sub (23E). The figure shows the closest to the axial line passage blocking the rotating section of the connection element of the motor shaft and the pump (69B) of the fluid in the line I of the selection of details of Fig.31. The figure includes a rotary connecting device (72) connected in the receiving socket (45A), i.e. blocking (25A) the passage closest to the center line (25), to which the shaft (113) of the turbine (112) is connected, at In this case, the injected mixture (31) or the extracted fluid mixture (34) passing in the passage closest to the center line acts on the turbine (112) and rotates it, or is pumped by the turbine if the fluid mixture passing through the corresponding turbine at the other end the shaft drives the layout. The sealing elements (66 of FIG. 32) control the flow, in the passage closest to the center line, of the fluid mixture passing through the positions (31, 34), above and below the plug (25A) and entering the throttle openings (59) for passage into radial passages ( 75) to the right and left to act on the turbines (112 of Fig. 31) at opposite ends of the shaft, in the passage (25) closest to the center line.

The other systems (70G of Fig. 30) of pipe columns are connected to the ends (90), however, a plurality of concentric pipes (2, 2A) or one pipe (2) can be used with a concentric pipe passage or a first annular passage, respectively, below the distribution sub (23E).

FIG. 35 is an enlarged view of a portion of the engine device (69B) and the fluid pump of the pipe string system (70G) in the part selection line G of FIG. 30. The dashed lines showing the invisible surfaces show the inner concentric column (2) and the outer concentric column (2A), between which the alternating upper and lower throttling holes (59) of the distribution sub (23E) of the flow control element (61) leading to the radial passages ( 75), create a feed of injection (31) and / or receipt (34) through the distribution sub (23E). The flow through the distribution sub can be used to operate the flow control element (61) shown in the figure, for example, which is a hydraulic motor and a fluid pump (69B) driven by simultaneously passing fluid flows at different speeds and / or corresponding pressures.

Figures 36 and 37 show a plan and a longitudinal section with a section line J-J and a section along line J-J, respectively, of a flow control device (61). A flow control device comprising an embodiment (69B) of an engine and a fluid pump (69) is shown as a fluid rotating device (112) connected by a shaft to a device (112) that can be used to pump fluid, for example in the form of a hydraulic turbine, designed to operate as a master and slave device at the ends of the shaft (113) in the casing (114) with the passage of fluid. The figures include connecting devices (89) connected to respective receiving sockets (45 of FIG. 32) for securing the flow control device (61). In addition, the blocking device (25A) and / or the sealing device (66) can be used to control the fluid passing in the passage closest to the center line and the concentric passage and in and between the radial passages.

Any form of coupling components or components driven by a fluid, for example a rotary coupling device (72) with seals (66) or bearings, rolling surfaces, sliding coupling components or mechanical elements such as planetary gears for operating the upper and lower turbines or impellers with different rotational speeds applicable in an underground environment for operating a hydraulic motor or pump can be used in the present invention. The device can be selectively installed in the receiving socket (45 of Fig. 32, 45A of Fig. 33) of the pipe string system using a cable connection device (68) and a cable lift (4A of Fig. 3) or a pipe connection device and a drilling rig with a flexible tubing pipe or conventional rig. Alternatively, the device may be selectively mounted between casing strings using devices such as a drawworks during normal installation. Other alternatives to the working component, for example, can be formed when fluid communication is made with the closest axial passage through the shaft to various other flows that can communicate through various other concentric passages and / or first annular passages suitable for operating the hydraulic motor and pump.

FIGS. 38 and 39 show longitudinal sections of alternative engine and pump devices (69) for differing embodiments (69C, 69D), respectively. The figures show: a device (69C) of a rotor (109) and a stator (108), which can operate during injection (31) or production (34), and is applicable for rotation of a fluid pump containing, for example, a turbopump or a screw pump with a rotor (109) and a stator (108), as shown in Fig. 38. On Fig shows a device (69D) with an electric motor (111), which can be used with an electric cable (110A) and fixed or with a seal (66) connection (110) connections without interruption, to actuate any pump downhole fluid for production (34) or for pumping fluid if the orientation is upside down. The fluid in each of the devices can be supplied using a distribution sub through the radial passage of the pipe string system.

As shown in FIGS. 6-39 and described below and shown in FIGS. 69-75 and 83-87, preferred embodiments of the distribution sub (23) of the present invention provide systems and methods that can be combined in any configuration or orientation to selectively control separately passing fluids for injection (31) and / or production (34) of fluid mixtures (38) from liquids, gases and / or solid particles. This selective control can be obtained at varying speeds and corresponding pressures, selectively creating a message through radial passages (75) and throttle openings (59), either directly (32) or not directly (35) to the passage closest to the center line (25, 26) another concentric passage (24, 24A, 24B, 25, 26, 54, 55), and / or directly, position (33) or not directly, position (37) to the concentric passage (24, 24A, 24B, 55) from the nearest to the center line of the passages (25, 26) or other concentric passages (24, 24A, 24B, 55) with selectively installed elements (61 Fig.1-123) ulirovaniya flow and / or embodiments (69A, 69B, 69C, 69D) of the flow control element. The flow control elements can be connected between the pipes of the inner concentric pipe string (2) and / or the outer concentric pipe string (2A), or can be lowered, installed and / or removed through the passages closest to the center line (25, 26) and connected to the receiving socket ( 45, 45A). Embodiments of an integrated tubing string system (70, 76) may be used to operate one or more substantially hydrocarbon and / or substantially water wells from one main wellbore and wellhead equipment.

On Fig and 41 shows a longitudinal section diagram of a known technique for underground operation and disposal of wastewater in the application of simultaneous flows and a method for separating hydrocarbon fluids on the surface, respectively, which together with the wells described above and shown in Fig.1-2 and Figures 46-47 depict possibilities for improving, combining, and / or replacing with preferred embodiments of the present invention.

Fig. 40 shows fountain fittings (10) connected to equipment (7) of the wellhead with a valve (81) of the annular space controlling injection (31) through the annular passage between the intermediate casing (15) and the last casing (3) with cementing into a fracture (18) below the casing shoe (16), which prevents upward flow in the annular space outside the intermediate casing. The figures show that the pressure can propagate (28) to the point (30) of the propagation of the fracture, ensuring the disposal of waste fluids into the underground reservoir. Cracks (18) may be able to close when injection is stopped (31). Solid waste particles can act as proppant, similarly to a single-stage fracturing treatment to intensify shale gas inflow at the lower end of production tubing string (2), where proppant (in general, finely sized sand particles) is injected to keep cracks open. This opening of the cracks can support, for example, fluid flow through all the cracks (18) to produce (34) gas from relatively impermeable shale formations, otherwise incapable of producing significant production. The inflow (34) of production, regulated by an underground valve (74), can pass simultaneously with the injection (31) of waste into the upper crack (18). Alternatively, injection (31) into a dedicated conventional waste disposal well can be carried out through fountain valves (10) controlled by a ground valve (64) and a tubing (2) to the point (30) of the propagation of the lower crack (18), essentially for water injection wells.

On Fig shows a hydrocarbon separator (115) located above the level (121) of the earth's surface, receiving a liquid mixture (38) from liquids, gases and / or solid particles obtained (34) from a tubing string (2), adjustable underground valve (74), controlled by line (79) control. The reduced pressure space in the separator (115) allows the pump (116) to pump a heavier relative density of the substantially aqueous fluid stream for processing for disposal. A lighter relative density, essentially liquid hydrocarbon is shown floating, position (117) on water, passing in an intermediate substantially liquid fluid stream (119) of hydrocarbons, with previously compressed substantially lighter relative density gases expanding and extending above the fluid level (118) to obtain a fluid in the uppermost substantially gaseous stream (120).

Figure 1-2, 6-7, 42-45, 48-52, 66-68 shows a diagram of a longitudinal section of systems (70, 76) of pipe columns, while the device system (70) of pipe columns of one well are individually applicable or in combination, below the intersection of the wells (51A of FIG. 51). Combined tubing string systems can be used to form a tubing string system (76) of multiple wells that can be used for underground processing and / or creating multiple fluid flows, while the combined elements are useful for replacing one or more conventional wells and / or completions or replacement of conventional processing devices, for example, such as those described above and below, and shown in FIGS. 1-2, 40-41 and 46-47.

In order to form a serial set of a pipe string system applicable essentially to hydrocarbon and / or substantially water wells and processing systems, elements containing, for example, conventional flow control elements (61) that may be suitable for working with with another kit, can be used to stimulate, measure and / or selectively control liquid mixtures of liquid, gas and / or solid particles, for one or more essentially hydrocarbon wells, essentially water wells, or combinations thereof, x well as combined by dissolving development and storage. Examples of such flow control elements include: ground pumps (116), ground valves (64, 81), gushing (10, 10A) and wellhead equipment (7) that can connect to the upper end of the system (70, 76) pipe columns, and which are applicable for controlling a single stream (31, 34) of a fluid mixture with multiple speeds and / or multiple flows (31, 34) of a fluid mixture with variable flow rates. In addition, underground valves (63, 74, 84) can be used to control the flow of liquid mixtures in the passages (24, 24A, 25, 26, 55). Additional flow control elements include downhole measuring instruments, speed switches, pressure activating mechanisms, acoustic or pulsating fluid signal transmitting devices, control lines (79) and / or other means of selective measurement, activation and / or control, including devices with a passage in one direction, ground or underground fittings (77), Venturi pipe (85), jet pumps (85), plugs (25A), casing shoes (16), packers (40), technological th fracturing equipment and / or motors and pumps (69) with electric or hydraulic drive.

On Fig and 43 shows a diagram of a longitudinal section and process control, respectively, options (70B, 70L,) for the implementation of a system (70) of pipe columns with underground separation of flows, element (61) flow control with an engine and a pump (69) fluid media that can be used to pump separated liquids. The figure shows the element (61) flow control option (23F) implementation of a distribution sub with an underground valve device. The figures include a liquid mixture (38) obtained at position (34) through passages divided into a plurality of simultaneous supply flows of a fluid mixture individually controlled by a plurality of valves (74). For example, the underground safety valve (74) of guaranteed operation in the event of an accident Fig. 91, controlled by a control line (79) connected in series or independently with each valve, and, for example, the device can be formed by connecting the valves with the upper and lower ends ( 90) distribution sub (23C or 23Y) Fig.22-25.

A check valve (84) installed at the lower end of the well controls the flow of one-way fluid mixture (38) into the pipe string (2, 2A) at the lower end of the pipe string system (70B, 70L), which can be obtained at ( 34) into various devices of passage spaces formed by a concentric pipe string (2, 2A, 2B of Figs. 14-16, 20 and 43, 2C of Figs. 43, 54 and 58), a first annular passage (55 of Fig. 1) and / or the walls (1A of FIG. 1) of the salt cavity. The interface between the liquids and / or the water surface (117 of Fig. 43) of the interface can be obtained by applying pressure or depressurizing the passage space by a flow control element (61), such as a fountain armature (10A), and, essentially, the gaseous naturally expanding stream (120) can be recovered at position (34) through the casing (2, 2A) to stimulate the flow of the substantially liquid stream (119). Alternatively, a substantially fluid flow (119) can be supplied using the following: natural ground pressure, a motor and a fluid pump (69), a surface pump (116), an electric submersible pump and / or other flow control elements through the passage pipe columns (2, 2A, 2B) or a concentric passage that may form between pipe columns and / or passage through underground formations.

The illustrated system (70L) of pipe columns of a single well, or a plurality of similar wells branching, for example, from a pipe system (70F Fig. 100-105), can be installed with a pressure control arrangement (49) with concentric inner pipe string (50) and external pipe string (51), and a transfer tool (58) for the passage of sludge flow can be used, for example, to create pipes with a diameter larger than, in general, practically used in the construction of wells for underground separation. After connecting the wellhead and / or gushing to the equipment, the pressure control system becomes a system (70, 76) of pipe columns with concentric pipe columns (2, 2A, 2B, 2C) and distribution adapters (21, 23) to perform injection functions or production, applicable to configure one or more wells for separating (70L) flow of fluid mixture in applications for individual wells or well connections (51A Fig. 50-52), similar to the pipe string system (76L) of Fig. 123.

The pipe string systems (70L, 76L) of FIGS. 43 and 123, respectively, are suitable for separating a fluid mixture into multiple streams of simultaneous supply of a fluid mixture from one well, from one or more vertically and / or transversely divided subterranean zones, or from caverns, where large suitable salt deposits are suitable for development by dissolving a separation space that can be used for wells or a transport pipeline. Larger separation spaces can be formed using the pressure-controlled tube columns of the present invention, or can be formed in various other ways, such as using underground separation to dissolve the walls (1A) of the cavity using the produced water or, as described in the methods of the present invention, or using unlimited available water sources such as the ocean. In cases where wastewater is obtained or such water is available, the present invention can be used to perform simultaneous extraction, dissolution, underground storage and / or separation of multiple flows of a fluid mixture entering or leaving an underground space or zone accessed by the system pipe columns.

On Fig and 45 shows a diagram of a longitudinal section and process control, respectively, of a variant (70C) of an underground system (70) of pipe columns, with selectable internal distribution sub (23) of the high-speed lifting column, sub (21) of the connecting chamber for distribution cracks and flow control elements (61) with an engine and a fluid pump (69). The figures show an inner concentric pipe string (2) and an external concentric pipe string (2A) extending downward from the wellhead equipment (7) and gushing (10A). During well construction, a distribution sub (21) of the connecting chamber can be used to feed (28A) proppant to hold open fractures (18A), for example, in shale gas production or waste disposal wells, through a perforated liner (19) with cementing (20) in the wellbore (17) of the formation and connected through the upper liner packer to the last casing (3) with cementing, in which the tubing string system (70C) is connected to the packer (40). Later, during the well’s life cycle, distribution sub (23A) can be used to reconfigure and form a high-speed lifting string to accelerate production and prevent waterlogging, which reduces, for example, corresponding hydrocarbon production.

The device can also be used to create access to the first annular passage (55) through the system (70C Fig. 44-45) of pipe columns, for example, to provide injection for waste disposal, while the distribution sub (23) adjacent to the crack (18 ) in the formation at a shallow depth can be made of various devices of distribution sub, for example, device (21) of the connecting chamber and distribution sub (23C and 23Y Fig.22-25). The plug (25A Fig.22-25) can be used to translate the fluid communication passages (24, 25) with the sub (21) of the connecting chamber, applicable to access the first annular passage (55) from the inner passage (25), while production from the distribution sub (23A) of the high-speed lifting column passes through a concentric passage (24) and axially upwards, and the waste water below the separation water surface (117), when the production is separated (115) on the surface, can be pumped (116) and pumped ( 31) through the gushing (10A) and distribute ny sub (21) connecting the chamber axially downwardly to actuate the hydraulic motor and the pump (69) feeding prey axially upwards.

For the pipe string systems (70B, 70L, 70C) of FIGS. 43-45, various possible devices for underground separation and subsequent waste disposal are described. For example, essentially the liquid stream (119) can be further processed and pumped by a pump (116) for disposal into the annular space shown by the dashed line in FIG. 42. Then, the flow (119) can be pumped through the valve (81) of the annular space in the annular space between the intermediate casing (15) and the last casing (3) with cementing, which can be adjusted using the shoe (16) of the casing to prevent the passage of fluid into the outer annular space, and pump, at position (31) through the fountain armature (10A), as shown in Fig. 44. Wastewater can be disposed of by creating a pressure message (28) with the fracture distribution point (30) in the subterranean formation. As shown in the figures, extracted underground pressurized fluids, such as compressed gas, a high pressure produced substance or a liquid mixture (31 of Fig. 44) of injected waste, can be used to drive hydraulic motors and fluid pumps (69).

The device of the system (70L) of pipe columns Fig. 43 can be used with an adapter (21) of the connecting chamber for selective communication with the underground surface (118) of the separation of hydrocarbons separated from the underground surface (117) of the separation of water. One or more submersible pumps (69), for example, with an electric drive, driven by expansion of compressed gas during the separation process, or injected fluids (31 of Fig. 44), can be used to facilitate selective removal of liquid hydrocarbon or water from the layers between different interfaces. If motors and pumps are undesirable, the gas flow can simply be shut off to allow for pressure increase in the well to allow fluid to flow through one or more passage elements.

The pipe string system (70C) of FIGS. 44 and 45 can be used with a distributor sub (21) of the connecting chamber to selectively create a fluid communication fracture and proppant during construction of the well. After that, the distribution sub of the connecting chamber can be used to selectively extract from the desired underground zones or to restrict water inflow by, for example, expanding gas from a shale gas reservoir suitable for driving hydraulic motors and fluid pumps (69) to pump liquid waste into the less shown deep layer. On Fig shows a distribution sub (23F) with a valve that can be adapted to use the connecting chamber and an additional distribution sub (23) for selectively controlling the flow of liquid mixtures in the pipe string system.

On Fig and 47 shows a diagram of a longitudinal section and process control, respectively, of a known gas-lifting device. The figures show the equipment (7) of the wellhead, from which the liquid mixture (38) can be obtained, at position (34) through the tubing (2) and fountain fittings (10), while essentially a stream (119) liquid fluid may rise through a concentric passage (25) closest to the center line using a substantially gaseous fluid stream (120). The rise occurs due to the injection of gas flow from the surface through the valve (81) of the annular space into the concentric passage (24) formed between the tubing (2) and the casing (3) with cementing (20) in the well bore (17) in the strata . The injection goes through a passage through underground formations (52) to a gas lift valve (84) installed in the passage (25) closest to the center line to create a fluid mixture of liquid and gas, thus increasing the flow rate of the fluid and decreasing the pressure at the point of contact with reservoir produced on the reservoir in order to increase production (34) above the level possible using normal operating pressures. An underground safety valve (74) with a guarantee of emergency response can be controlled via a control line (79), fountain valves (10), single-acting gas lift valves (84) and an annular space valve (81) for use to selectively maintain underground pressures in the well and to intensify its production (34), subject to processing on the surface and / or the presence of gas for lifting during operation.

Conventional gas-lift devices are widespread, but require the supply of gas suitable for injection from the surface, which, together with the corresponding structures on the surface, creates significant economic and logistical difficulties for remote development and / or with increased environmental requirements. For many hydrocarbon developments, the present invention is applicable for selectively controlling and re-injecting underground separated gas at sites suitable for recovery, and it is not necessary to supply from the surface of the injected gas and associated structures on the surface.

Figures 48 and 49 show diagrams of a longitudinal section and a process control, respectively, of an embodiment (70D) of an underground pipe system (70) suitable for separating a fluid mixture of a liquid and compressed gas, essentially, into a liquid and essentially gaseous fluid flows. Separated flows can be used for selective re-injection and gas lift of a substantially liquid stream, especially where surface processing and gas injection are economically unjustified and / or impractical. For example, the use of the embodiments shown in FIGS. 48 and 49 may be economically viable in remote subsea development and low-profitable development where there is no infrastructure.

The liquid mixture (38) can be obtained (34) through a pipe (2) connected by a packer (40) with a passage through underground formations (52) contained in production casing (3) with cementing (20) in the well bore (17) in strata and casing (14) direction. The liquid mixture (38) can achieve a pressure activated valve (63) regulating the radial passage of the distribution sub of the embodiment (23W), applicable with the distribution sub of the embodiment (23H) of implementation with the one-way valve and the venturi pipe (85), for evacuating the liquid from the space gas lift separation. The pressure in the concentric passage (24) can be selectively controlled by a nipple valve (77) mounted on a fountain valve (10A), on a substantially separated fluid gas stream (120), which can be completely or partially diverted through a gas lift valve (84) of the distribution valve a sub of embodiment (23G) to facilitate substantially raising the fluid stream (119) of a fluid sampled from the concentric passage (24) below the liquid level (118) and through the distribution sub (24H) of the venturi pipe (85).

To maintain the tightness of the well in the event of failure of the fountain valves (10A), the underground valve (74) is controlled via the control line (79), and the distribution sub (23W) of the pressure-activated valve (63) inhibits the flow of the underground fluid mixture (38) under pressure while, similarly to a conventional gas-lift well, only limited equipment in the annular space is not sealed. The addition of an annular pressure relief valve or an optional valve-controlled distribution sub (23F) suitable for controlling both the closest to the centerline and concentric passages can be used to hold pressure in space if required.

50, 51 and 52 are diagrams of side views of various embodiments (76A, 76B, 76C) of implementing a plurality of wells with a string pipe system (76) applicable essentially to hydrocarbon and essentially water wells, such as wells production / injection of wastewater, water flooding and development by dissolution / storage, respectively, using the intersection (51A) of the wells with many wells extending downstream from one main wellbore (6) and wellhead equipment (7). Many wells can provide access to rocks (103) for underground injection, relatively horizontal reservoirs (94) or folded reservoirs (95), and salt deposits (5) located between underground formations (106).

The devices of the system (76A, 76B) of tubular columns of hydrocarbon or geothermal wells, suitable for the disposal of water or waste water and water flooding, can pump water into the rock (103) or reservoir (104) relative to the horizontal passage of water, with production from folded (94), disturbed, fractured, and / or water displaced by the reservoir using one or more of a plurality of wells to dispose of wastewater and / or to increase the pressure in the reservoir to produce hydrocarbons or steam from the geothermal reservoir.

The devices of the pipe string system (76C) can be used to dissolve and selectively access the hydrocarbon products of gravitational separation in the space in the walls (1A) of the cavern of the salt deposit (5) with sealing on its upper end of the last casing (3) with cementing and a shoe ( 16) casing string. In the development by dissolving the cavity space, you can use sea, waste or produced water of various other embodiments. Essentially, hydrocarbon fluid mixtures from liquids, gases, and / or solid particles from wells or pipelines can be separated, stored, and / or selectively accessed in a cavity using distribution sub, selectively supplying various fluid mixtures from layers between levels (105 ) gravitational separation according to the relative density of fluids, using, for example, distribution sub (21) of the connecting chamber. Essentially, aqueous fluids descending to a lower level (104) are useful for simultaneously displacing into a storage, increasing pressure in a cavity and / or developing a space by dissolution.

The methods and devices of Figs. 53 and 57 shown in Figs. 53 and 57 are adaptable with the distribution sub (23J) of Figs. 54-56 to form the pipe string system (76K) of Fig. 59, for completing the subsea well of Fig. 53.

On Fig shows a longitudinal section of underwater equipment (7) of the wellhead installed above the seabed (122), which can be used with systems (70A, 70B, 70C) of pipe columns Fig. 50-52 and an adapted distribution sub of the connecting chamber of Fig. 58. The figure shows underwater connecting devices (107), equipment (7) of the wellhead and one main shaft (6) installed in the rock of the formation (106) and which contains a connecting chamber (43) connected to the equipment of the wellhead with output channels, passing to the lower end of the well. The ends (90) of the pipes (39) of the output channels can be connected to many wells.

On Fig shows a plan above a side view, with dashed lines showing the invisible surface of the option (23J) implementation of the distribution sub (23). The figure shows the connecting devices (26) closest to the center line of the passage, suitable for connecting the closest to the center line of the passage above and below the distribution sub with radial passages (75), to create a fluid communication with throttle openings (59), which can be connected to concentric passage. As shown in the figure, the receiving sockets (45) can be used to selectively control the passage closest to the center line and / or the radial passage using a flow control element, for example, a twin packer (22 Fig. 93A) or plug (25A of Fig. 93), installed through the passage closest to the center line and connected to the receiving socket. A plurality of concentric pipes (2A, 2B, 2C of FIGS. 54 and 58) can be used to form multiple passages of concentric pipes for connecting to one or more throttle openings (59) from a radial passage (75).

On Fig and 56 shows an isometric view with a line K and with an increase in the view of the part highlighted by line K, respectively, the latter shows in cross-section a cross section of the sub (23J) of Fig. 54. The figures show the throttle openings (59) of the radial passage (75) and the receiving sockets (45), which can be used to selectively connect flow control elements to control the flow of the fluid mixture.

On Fig-56 shows concentric passages (24, 24A, 24B, 25, 26, 53, 54, 55) that can be formed between concentric pipe columns (2, 2A, 2B, 2C, 50, 51) and the passage through the underground formation (52 Fig. 53), and each throttle hole can be made with the possibility of individual access to a different concentric passage (24, 24A, 24B). Flows can pass at positions (32, 35) into the passage closest to the center line, directly, at position (32) from the first concentric passage, or, not directly, at position (35), from the first concentric passage through another secondary concentric passage. Alternatively, the flows may pass through positions (33, 37) into a concentric passage through a throttle opening (59), either directly at (33) or not directly at (37) from a first concentric passage or from a first concentric passage through a secondary concentric passage. This is ensured by any configuration or orientation of the flow between the passages with multiple distribution sub (23J), which can be connected in series with the orientation of the radial passage with the possibility of change, for example, by reversing or flipping one of the distribution sub. The throttle openings (59) can be connected to form a fluid communication between the passages, and the throttle openings can be connected to many concentric passages (25, 24, 24A, 24B, 55), in the pipe (2) closest to the axial line and between it and the plurality concentric pipe columns (2A, 2B, 2C) and passage through an underground formation (52).

The manifold (43 A) of the connecting chamber can be adapted with a plurality of concentric columns (2, 2A, 2B, 2C) and a sub (23K) of FIG. 58 to replace the gate valve (74) of FIG. 57. The pipe string system (76K) shown in FIG. 58 and formed by adaptation can be used to selectively control multiple flows of fluid simultaneously during installation, for example, in the subsea well of FIG. 53.

On Fig-65, shows the adaptation of another manifold connecting chamber, which uses many components of the system of pipe columns of the present invention. The manifold (43A) of the connection chamber Fig. 59-60 is adaptable to form a distribution sub (23L) of the embodiment Fig. 61-65, which can be used in combination with an embodiment of a distribution sub (23X) to form a variant (76J) of a pipe system columns, which can be used to perform the same function with concentric pipe columns (2, 2A) Fig.61-65 instead of parallel pipes 78 (also shown in Fig.58) and pipes 71 Fig.59-60. Concentric pipes can be used to improve the flow rate in the passage through underground formations for the production and injection of simultaneously flowing flows of a fluid mixture at different speeds, while the flow fitting with two through holes required for the manifold (43A) of the connecting chamber Figs. 59-60 can replace the fountain fittings with one channel for the system (76J) of pipe columns Fig.61-65, to simplify the installation of flow control elements in the passage closest to the center line, for example, eliminating the need multiple installation of the cable line (4A Figure 3) of the elevator, which is required for the fountain with two through holes.

The connecting chamber may comprise a bottom (42) of the camera with a receiving socket (for example, 45A is shown in Fig. 33 if the output channel extends axially downward or 45C in Fig. 65) for connecting the extension cord (48 Fig. 95-96) of the selector (47 Fig. 95-96) of a channel that can be used to complete the guide surface (87) of the fluid and device in the connecting chamber. The walls (41) of the chamber can be connected with the position (44) with the pipes (39) of the output channels and additionally connected with connecting devices of the upper end of the distribution sub (23X) closest to the center line of the passage with a receiving socket (45) for connecting the elements (25A, 61) flow control and radial passage (75) for fluid communication between the passages. As shown in the Figures, the ends (90) of the arrangements can be connected to the pipes (2, 2A, 71, 78) of one main wellbore at the upper end and a plurality of well casing at the lower ends.

On Fig and 60 shows a plan and isometric view, respectively, of the distribution sub (43A) of the connecting chamber, applicable for flows of simultaneous injection and production. As shown in the Figures, the first pipe (71) of the main barrel and the second pipe (78) of the main barrel are parallel and have access to divided sections of the chamber with valves (74) below, regulating the pipes of the output channels connected to the sets (66) of seals with other connecting chambers (43 Fig. 54). The connecting chambers of the present invention, shown in FIGS. 59 and 60, provide, for example, simultaneous production from two wells and injection into one well, similarly to the pipe string system (76B) of FIG. 51.

On Fig and 62 on the plan and side views, respectively, with dashed lines showing invisible surfaces, shows the system (76J) of the pipe columns and the manifold (43A) of the connecting chamber with a distribution sub of the option (23X) implementation to adapt the connecting chamber (43 ) The figures show the inner concentric pipe string (2) and the outer concentric pipe string (2A), which are equivalent in function to the first pipe (71) of the main barrel and the second pipe (78) of the main barrel, respectively, while simultaneously, the liquid mixture passes into positions (32, 35) in one of the three passages closest to the center line (25, 26), either directly, position (32) or not directly, position (35) from the passage (2B, 2C Figs. 54 and 58) of the concentric pipe , or in position (33, 37), in a concentric passage (24) through the throttle hole (59), or y, position (33) or not directly, position (37), and then through concentric passages (24, 24A, 24B, 55) when additional concentric pipes (2B, 2C Figs. 54 and 59) are present at the upper end (90A )

The extension cord (48 of Figs. 95-96) of the channel selector (47 of Figs. 95-96) can be connected to the receiving socket (83) of the bottom of the connecting chamber, while the guide surface (87) ends across one passage closest to the axial line (25) blocking other passages closest to the center line, for example, to install a plug (25A of Fig. 66) to divert the flow at position (33, 37) to the concentric passage (24) or at position (32, 35) in the lower left nearest to the axial line line passage (25).

On Fig shows an isometric view of the column (76K) and distribution sub (23X) Fig. On Fig shows the inner concentric pipe column (2, 71) and the outer concentric pipe column (2A, 78), dotted lines show the end pad (90A) of the additional concentric pipe (2B) used, if necessary, and the corresponding, applied if necessary, a throttle bore (59A), which can be used with other distribution sub (23Y FIGS. 14-16, for example), which are connected to the upper end (90). The connection may create a fluid communication between the lower left passage closest to the center line (25 of FIG. 61) to change passage elements using the sub of the present invention.

On Fig and 65 shows a plan and a longitudinal section along the line L-L, respectively, of the system (76K) of pipe columns and distribution sub (23X) Fig.61. The figures include a flow control element (61), which is shown, for example, as a plug (25A) installed through the passage of the inner concentric pipe string (2) closest to the center line using a channel selector. As shown in the figures, the outer concentric pipe string (2A) is mounted in fluid communication through the manifold (43A) of the connecting chamber and the radial passage (75) of the distribution sub (23X). Alternatively, the twin packer (22 of Fig. 93A) may be connected to one or more of the receiving sockets (45) to block the radial passage and selectively fluid connection between all three passages (25) closest to the center line, the outlet pipe (39) connecting chamber (43). Various combinations of injection (31) and production (34) between passages (25) can be used to selectively control simultaneously flowing fluid flows.

On Fig, 67 and 68 shows a diagram of side views of various options (76D, 76E and 70E, respectively) for the implementation of valves (74) flow control and systems (70, 76) of pipe columns. The figures show the elements (61) for regulating the flow of valves above, below, and between the connecting chambers (43) and distribution adapters (23) for selectively controlling the flow closest to the axial line of the passage (25) passing through the twin packer (22) and the concentric passage (24), between the inner concentric pipe string (2) and the outer concentric pipe string (2A), which is shown blocked from the passage closest to the center line and diverted through the radial passage of the distribution sub second stopper (25A).

The figures show selectively configurable flows passing directly, position (32) to the passage closest to the center line or not directly, position (35) through the upper right intermediate connected passage (26) closest to the center line, or alternatively directly, position (33 ) into a concentric passage or indirectly, position (37) through an intermediate connected passage of the connecting device (26) of the lower passage closest to the center line. Throttle openings (59) are shown with the possibility of connecting with one or more concentric passages between two or more pipes, while flow control elements are selectively installed and / or configured across the throttle openings of radial passages or other passages for selectively influencing fluid flows, passing through a sub (23Q).

The embodiments shown in the figures correspond to the distribution sub of Fig. 76, the part selection line P of Fig. 77 corresponds to the part P of Fig. 78. The fracture lines representing the remote areas show the adaptation of the connection chamber (43) applicable to the flow control elements of Figs. 75 and 81 to form a distribution sub (23R) of Fig. 82.

FIGS. 78 and 80 are shown in enlarged view of a portion of the adapted connecting chamber (43) within the part selection line P of FIG. 77 and an isometric view, respectively. The figures show the elements of the inner concentric pipe string (2) and the external concentric pipe string (2A) forming a concentric passage (24), with throttle holes (59) connected to the upper end (90 of Fig. 81) of the connecting pipe (93 of Fig. 81 ), and with the lower end (90 of FIG. 81) connecting to the throttle holes (59 of FIG. 75) of the sub (23D of FIG. 75) to form a pipe string system (76F) of FIG. 82.

Since fluid mixtures of liquid and / or gas may contain abrasive solids and fluid mixtures passing at varying speeds can cause erosion, it is necessary to design functional changes in the distribution sub, for example, longer flow deviations with a smoother change for various applications, such as for development by dissolution and application of hydrocarbon liquid mixtures with high pressure and high speeds.

83-87, a distribution sub of an embodiment (23T) is shown applicable to minimize frictional flow resistance at high speed or highly erosive environment. Since such embodiments with a long offset are more difficult to understand than shortened versions with right angles, various embodiments of the distribution sub are described in view of the above. However, it should be understood that, within the scope of the appended claims, the above-described embodiments of the distribution sub are designed by the connecting chamber (21, 43) of the present invention to minimize frictional resistance at high speeds and in highly erosive environments similar to position 23T of Figs. 83-87 in the embodiments applications for multiple wells or positions 23Z and 47A of FIGS. 117-122 in applications for one well. More than two output channels and / or several blisters of radial passages and / or divided concentric passages can be used with two sub-adapters (23T) of the connecting chamber having connected ends of the output channels, similar to the sub 23M of Fig. 68, for applications of concentric pipes. For example, dual packers, blocking plugs, and pressure-controlled acoustically controlled fluid-controlled flow control devices and / or flow control choke devices can be installed in the receiving sockets of the output channels for selective passage control.

On Fig and 86 shows a plan and longitudinal sections along the lines Q-Q and R-R, respectively, the break lines show the remote sections of the layout corresponding to the sections in the isometric views of Fig and 87, showing the distribution sub (23T) Fig. The figures show the installation of the flow control element, shown in the form of a blocking plug (25A) installed and removed on the cable (11 of Fig. 3), which can be installed through the passage (25) closest to the center line of the inner concentric pipe string (2) with a selector ( 47 Fig. 96) of a channel applicable for completing the guide surface (87) of the passage closest to the axial line and excluding other flow control elements in the form of an outlet channel plug with a selected nipple profile of the receiving socket (45) for blocking fluid communication in the casing (39) with one outlet channel from the passage closest to the center line (25). The concentric passage flow (24) can communicate below the plug, directly, at position (32, 33), with the passage of the output channel of the barrel casing, or, not directly (35, 37), with various other sub (21, 23) connecting to the upper the end (90) of the connecting chamber through the radial passage blister (75). Connected in the manifold (43A) of the connecting chamber, the flow from both output channels can function by installing a twin packer (22 in FIG. 93A) across the throttle bore (59) of the radial passage (75).

On Fig and 87 shows a projection of isometric views with sections corresponding to Fig and 86 and the break lines of the distribution sub (23T) Fig. The figures show isometric views of a different orientation in perspective of a flow passage in a radial passage blister (75) and a flow control element (61) as a blocking device (25A). Other flow control elements, such as a pressure-activated single-acting valve, can be used to deliver a substantially lighter relative density fluid flow of the first well to a heavier flow of the second well to reduce hydrostatic pressure to the second well, and thus increase flow rate.

The adapters of the connecting chamber of a similar design with blisters (75) of the radial passage and non-continuous casing pipes of the output channels with receiving sockets (24) can be used to replace the connecting pipes (93 Fig. 81) and the distribution sub (23D Fig. 75) or to replace the distribution sub (23R Fig. 82) in the pipe string system of Figs. 88-116, when, for example, erosion cutting or layout flow is a concern when passing higher flow rates. For example, such development concerns are operations by dissolving essentially in water wells, or with propagating a proppant fracture to produce shale gas or in reservoirs of low permeability sandstone, essentially in hydrocarbon wells.

Direct flows (32, 33) or non-direct flows (35, 37) between the passage closest to the center line (25, 53) and the concentric passage (24, 54) can be used in the inner concentric pipe (2, 50) and the outer concentric pipe (2A, 51) for selectively controlling flows. The sludge passage element (58) can be installed in and removed from the connecting chamber (43). Deflecting wedges (124) can be used for separation in terms of several passages through underground formations from one main trunk (6 Fig. 50-53 and 106-116). The remaining sections of the configuration (49) with pressure control can be used as an external element of the intersection of wells (51A Fig. 50-53 and 106-116).

Figures 106-116 show an embodiment (76G) of a pipe string system (70) comprising a distribution sub (23R of Fig. 82) that can be connected by a packer (40 of Fig. 92) of a connecting chamber (43 of Figs. 88-89), forming the intersection of wells (51A). The figures show a distribution sub (23R), which is formed from the manifold (43A) of the connecting chamber, which can be formed from the connecting chamber (43 of Fig. 80), with nipple elements (91 of Fig. 94) creating receiving receptacles (45), connected by a distribution sub (23D of Fig. 75), which can be connected to valves (74 of Fig. 91) applicable to divert the flow from one well intersection (51A) through the radial passage (75) of the distribution sub (23D). The left borehole flow can be diverted through the radial passage (75) to the concentric passage (24) using a plug (25A of Fig. 93) that connects to the receiving socket (45) and descends through the passage (25) closest to the center line, and the flow of the right well can be supplied through the passage (25) closest to the center line, both wells are controlled by underground safety valves (74) between the pipes of the string closest to the center line (2) and production packers (40) in the annular spaces (24A) at the lower end of the well.

Fountain fittings and / or wellhead equipment can be used when connecting to the upper ends (90) of one main trunk (6) from which two wells pass axially downward, at the intersection of wells (51), to vertically and / or in plan divided underground zones, this ensures the tightness of two conventional wells passing through one equipment of the wellhead and the main wellbore.

Figures 107-111 show longitudinal sections along the line XX of the distribution sub of Fig. 106; Figs. 108, 109, 110, and 111 have lines Y, Z, AA, and AB, respectively, related to magnified views of Figs. 113-116 . The figures show a combination of elements (23R, 76F of Figs. 82 and 43 of Figs. 88-89) of a pipe string system with various flow control elements (61) forming the intersection of wells (51) with the upper ends (90) connecting to the pipes of one main wellbore and / or wellhead equipment. After construction, concentric pipes (50, 51) and corresponding passages (53, 54, 55) can become production and / or discharge pipes (2 or 71, 2A or 78, 51) with corresponding passages (24, 24A, 25, 55) . The dashed line between the upper and lower ends represents a continuation of the device of Figs. 107-111, and the proximity in plan of two wells below the intersection of the wells (51A) is shown illustratively, since the wells below the intersection of the wells and one main well have, in general, significant separation in plan for access to significantly vertical and in plan divided underground zones.

In Fig. 112, in an enlarged view of a portion of the system (76G) of pipe columns in the extraction line W of the component, Fig. 106 shows an inner concentric pipe column (2), an external concentric pipe column (2A), forming an internal passage (25) and a concentric passage ( 24) a connecting chamber (43) around the manifold (43A) of the connecting chamber to form a well intersection (51A). Various flow control elements can be installed through the passage (25) closest to the center line using a cable (11 of Figure 3) and a cable lift (4A of Figure 3), with a channel selector (47 of Figure 95-96) that can connect to a receiving socket (83) for selectively blocking one passage closest to the center line and creating a message with another to lower the device for installation in it. Alternatively, a channel selector (47 of FIGS. 95-96) connected to a receiving socket (83) can be used to simultaneously pass fluid flows at position (32, 35), to a passage closest to the center line, or to create a fluid message in positions (33, 37) in the concentric passage (24), depending on the other connecting elements of the distribution sub used.

On Fig shows a view with an increase in the portion of the system (76G) of the pipe columns in the line Y of the selection details Fig.108. The figure shows a distribution sub (23D) with a radial passage (75) and a receiving socket (45) of a nipple profile between the pipes (39) of the output channels and the inner concentric pipe columns (2).

On Fig shows an enlarged view of a portion of the system (76G) in the line Z of the allocation of details of Fig.109. The figure shows the elements (61) for regulating the flow of the underground valve (74), which can be used to selectively control the passage closest to the center line (25). For example, the figure shows the control elements of the underground valve (74) in the form of a throttle valve (127), with corresponding receiving sockets for sealing the valve or installing other flow control elements.

FIG. 115 shows an enlarged view of a portion of the system (76G) in the line AA of the part isolation of FIG. 110, shows internal concentric pipe columns (2) passing through the bottom (42) of the connecting chamber (43), while the walls (41) chambers and associated pipes (39) of the output channels function as a concentric pipe for a common concentric passage (24). A common concentric passage can be used for pumping (31) and return (34) during circulation before installing the packer (40 Fig. 116), and the two concentric passages (25) closest to the centerline are also used for pumping (31) or production (34 ) in the plan and / or vertically divided underground zones.

On Fig shows an enlarged view of a portion of the system (76G) of the pipe columns in the line AB highlight the details of Fig. 111. The figure shows the pipe (39) of the output channels connected to the upper end of the flow control elements of the production packer (40), which are shown connected to concentric pipe columns (2A) by connected devices (60) or wedge gripping segments. The concentric passage (24A) is shown by a blocked packer (40), and the passages (25) closest to the centerline of the two wells passing from the connecting chamber of the wells (51 of Fig. 107) can be divided for passage to vertically and / or in plan divided underground zones .

On Fig shows a plan with the AK-AK line from above from a side view along the line AK-AK, sub (23). An embodiment (23Z) of a distribution sub (23) is shown comprising a connecting chamber distribution sub (21), an adapted connecting chamber (43) with ends (90) connected to pipe columns of another element containing at least an outer pipe column (2A) is shown ) and an inner concentric pipe string (2) with the channel (25) closest to the center line and the first receiving socket (45) of the upper end above the bottom (42) of the connecting chamber, which can be used as a connecting second receiving socket before. The axial lower output channel (39) can be isolated from the side inclined output channel (39) by connecting a double packer or pipe across the first and second receiving sockets to seal across the output channel connection (44) to function as a channel selector for the axial aligned output channel. The passage of a twin packer or sealing pipe from the first inlet socket (45) to the third inlet socket (45) of the lower end can separate the passage closest to the center line (25) from the concentric passage (24) by sealing the throttle holes (59) of the flow sub. Alternatively, the flow control blocking element or channel selector may be connected in a second receiving socket (42) to cross the flows from the passage closest to the center line, through the concentric passage (24, 24A), to the surrounding passage, which may include, for example, a first ring passage. The flow below the blocking or channel selector can be diverted to the concentric passage (24) through the throttle openings of the sub, below the lower receiving socket (42) of the sub (21) of the connecting chamber. The oblique orientation of the output channels can be used with high-speed or erosion-prone fluid mixtures to prevent the flow of the distribution sub (23Z) from cutting.

The adapter (21) of the connecting chamber can be adapted with an additional concentric pipe string (2B), indicated by a dashed line, forming an additional concentric passage (24A) with which the output channel (39) can communicate with or through which it can be moved through the pipe insert (46) (39) the output channel to the pipe farthest from the center line (2B). A plurality of outlet duct pipes (39) can selectively communicate with a plurality of additional concentric tubes using an outlet duct pipe and a channel selector to pass through the intermediate passage to form new (23Z) implementation of a distribution sub that can be used to create a message closest to the center line of the duct (25) with any concentric passage. A plurality of distribution sub (23Z) can be combined to form new distribution sub for fluid communication between a plurality of different concentric passages through a channel closest to the centerline between a plurality of distribution sub (23Z).

On Fig shows a plan with the AQ-AQ line above the longitudinal section along the line AQ-AQ with the tear lines indicating the remote areas of the embodiment of the adapted channel selector (47A), which can be used in pipe pipe systems Fig.119-122. The figure shows a plurality of guide surfaces (87) for the corresponding plurality of additional throttle openings (59 of FIGS. 119-122) of the outlet channel, suitable for supplying the channel selector to the passage closest to the center line using the pressure of the passing fluid stream. Used, if necessary, the flow control element (61), shown, for example, as a ball valve (84), can provide flow through the channel selector when pumping through the passage closest to the axial line for alignment with the system output channel (70G Fig. 119-120 )

Adapted embodiments of the channel selector (47A) can be combined with other flow control elements (61), for example, connections (60) for receiving sockets (45 Fig.119-122), dual packers (22) to block the passage of the output channel of the connecting chamber and / or blocking throttle openings (59) between passages, single-acting internal valves (84), or a connecting receiving socket (45B) for a service tool on a cable, work string of a composite casing pipe or flexible pump-compressor oh pipe. A fluid circulating between the passage (25) closest to the center line and the concentric passage (24 of FIGS. 119-122) can be used to facilitate the passage of the channel selector in the passage closest to the center line, for example, to perform one or more stages of the development of a fracture in the reservoir shale gas.

Embodiments of the channel selector can be pumped through the passage closest to the center line to connect with throttle openings in the passage closest to the center line. Alternatively, embodiments of the pumped channel selector can be suspended, for example, on a cable (11 of Figure 3) and a cable lift (4A of Figure 3) or a work string of composite casing strings or a flexible tubing on a rig, lifting the carrier rig can be supplemented by the ability to selectively control the circulation of the channel selector, while supplying fluid flows of varying speed to remove or supply a fluid mixture. For example, fluid mixtures of liquids, gases, and / or solids may be removed or disposed of during operations such as proppant fracturing for waste disposal, shale gas production, or the installation of a gravel pack in an unconsolidated reservoir.

FIGS. 119 and 120 show a plan with an AP-AP line above the longitudinal section along the AP-AP line and an isometric view showing longitudinal sections of FIG. 119 with tear lines, respectively, of an embodiment of a pipe string system (70G). The figures show a channel selector (47A) with a connecting profile (60) connected to the receiving socket (45) of the distribution sub (21) of the connecting chamber, with three throttle openings (59) of the output channel aligned with the channel selector of FIG. 118. The figures show the corresponding twin packer, which can be used for the throttle openings of the sub, while the fluid below the channel selector can be used to circulate at position (33) in the concentric passage (24) through the lowest throttle openings of the distribution sub (23), for facilitating the installation of the channel selector so that a fluid mixture of liquids, gases and / or solid particles can be created through the passage closest to the center line to position (33) in the first annular passage using the control surface (87) and the pipe (39) of the output channel forming the radial passage element (75).

Installation of the channel selector in the passage closest to the center line for subsequent operations can take place, for example, using a cable hoist (4A of FIG. 3) and a cable (11 of Figure 3) for selectively installing the channel selector adjacent to the pipes of the output channels. Twin packers (22) can be used to block throttle openings in the walls of the pipe closest to the center line to form a circulation flow path in the passages (24, 25) of the pipe string system for injection and / or extraction, for example, during propagation (28B Fig. 123) underground fractures (18B of FIG. 123) by means of injection of proppant, followed by extraction of the proppant that has precipitated and subsequent selective production flow and / or limitation of water inflow.

Alternatively, for example, feeding the channel selector in combination with the output channel of the distribution sub (21) of the connecting chamber of the pipe system (70G), using, for example, a flexible tubing string or a working string of composite casing, which is facilitated by transfer between passages (24, 25) through throttling holes in the inner concentric pipe (2), can be used to accommodate a fluid mixture of liquids and proppant solids, which can be pumped through a flexible tubing the cabin and the outlet for crack propagation. After that, the fluid pumped through the concentric passage (24) passing through the non-return valve can be used to supply fluid through the channel selector (47A) and into the passage (25) closest to the center line to raise the proppant that has fallen from the bottom up. In comparison, the state of the art requires removal from the top down using a venturi pipe of proppant that has precipitated. After the fluid flow passes through the channel selector, the channel selector can be re-set to directly circulate proppant removal, as described below and shown in Figures 121-122. In this way, several stages of fracture development can be performed without having to remove the working string of the flexible tubing or the composite working string of the tubing from the well.

On Fig and 122 shows a plan with a line AN-AN section above the longitudinal section along the line AN-AN, with dashed lines showing invisible surfaces, and an isometric view showing the longitudinal section and section along the break lines of Fig, respectively, an embodiment of a pipe string system (70H) that can be used to remove particulate matter from an aisle closest to the center line. After combining the channel selector (47A FIG. 119-120) and injecting or extracting the fluid mixture through the radial passage (75) of the outlet channel pipe (39), as described above and shown in FIG. 119-120, the channel selector (47A) combine with throttle holes (59) in the pipe (2) closest to the center line to create a higher circulation flow between the passages (24, 25) using the double packer wall (22) to block the radial passage (75) of the output channel pipe (39) originally used to feed, for example, proppant.

If, for example, hydraulic fracturing using proppant is carried out in shale gas deposits at the beginning with the installation of a channel selector at the lower end of the system (70G Fig. 119-120), after proppant has precipitated, the fluid can be circulated by pumping through a concentric passage and returning through a one-way valve actions (84) of the channel selector to raise the proppant and ensure the channel selector moves downward, for example, on a flexible tubing, until the guide surface (87) of the channel selector (47A) is aligned with the throttle GOVERNMENTAL holes (59) directly below the radial passage (75) for providing increased volume for circulating fluid between the passages (24, 25) for removal of precipitated proppant. After that, the channel selector (47A) can be combined with the next radial passage and the process can be repeated. One possible device is the operation of circulating through a flexible tubing in stages from the bottom up, which can be connected to the receiving sockets (45B of Fig. 118) of the channel selector, with a fluid pumped downward through a concentric passage (24), turning on the first open throttle holes in the passage (25) closest to the center line below the tight connection of the tubing string string to the receiving receptacle (45B) of the channel selector. Another possible device includes, for example, a composite tubing that can be used to control surface pressure, and which includes, for example, a rotating head.

123 is a longitudinal sectional diagram of an embodiment of a tubing string system (76L) applicable to a plurality of wells and well types. The figure shows one pipe string (51), on the right, installed with a pressure-controlled string for the formation of one column of injection and / or production concentric pipe (2) in the passage through underground formations connected to the intersection of wells (51 A) and further connected to a system (70) of pipe columns, with distribution adapters (21) connecting chambers, dual packers (22) and plugs (25A) to form a system (76L) of pipe columns that creates fluid communication between underground near zones (n same 1Y, 1W, IV, 1U, IT) equipment and the wellhead (not shown) at the upper end of the main barrel (6). Concentric pipe columns (50, 51) can be installed with a pressure-controlled pipe assembly to become a concentric inner pipe (2) and outer pipe (2A), respectively, after the formation of the well, depending on the application, and the removal of the inner column (50 )

The types of wells used can include essentially hydrocarbon and / or essentially water wells, for example, the right production hydrocarbon well can be translated, position (33), into the concentric passage (24) of the left well, while position (34), fluids are injected, position (31), down into the left borehole to exit at the end or enter the distribution sub (21) of the connecting chamber, with plugs (25A) above and below to direct the flow into the first annular space (55 ) sealed in walls (1A) ka true or into the passage through the underground strata (52). The hydrocarbon liquid mixture may be separated into gas, liquid hydrocarbon, water and / or solid particles. If water is obtained, it can be used to develop caverns by dissolving the walls (1A), while the dual packers (22) and plugs (25A) can be rearranged to remove the resulting brine. The system of pipe columns can be used for production (34), taken through a concentric passage (24) by the pipe of the outlet channel from the first annular passage (55) to position (35), the channel closest to the center line for lifting upward. Essentially, a liquid mixture with gas can be taken from the uppermost distribution sub (21) of the connecting chamber, or fluids of different relative densities, essentially gaseous or liquid hydrocarbon and / or water, can be taken from other distribution subs (21) of the connecting chamber between adjacent zones (1T, 1U, 1V, 1W, 1Y) by rearrangement of flow control devices (22, 25A).

Other applicable well types include, for example, essentially hydrocarbon wells, where distribution chambers (21) of connecting chambers can be used to perform multi-stage fracturing to create fractures (18A) in close areas (1T, 1U, 1V, 1W, 1Y) in this case, pressures can be transmitted, position, (28A) to the crack propagation point, and at the same time, proppant can be used to keep the cracks open for passage, for example, gas from shale gas deposits or a fluid mixture from a low permeable sandstone reservoir sti, and the right well may have access to other deposits, reservoirs or act as a disposal well for wastewater.

Other suitable types of wells include, for example, essentially geothermal wells or wastewater recovery wells, for example, removing a plug (25A) from a well intersection (51A) and installing a twin packer to allow injection of water through a fracture into the right well ( 18A) the geothermal collector of the left well, which can be selectively controlled by distribution chambers (21) of the connecting chambers, which provide access to selected nearby zones (1T, 1U, 1V, 1W, 1Y) or injection of liquid waste from the right kvazhiny in vertically separated close zone (1T, 1U, 1V, 1W, 1Y) left-wells.

Other types of usable wells include, for example, combinations of substantially hydrocarbon and essentially water wells producing water with high temperature and pressure from the right well or supplying water to the geothermal reservoir of the right well producing steam, further directed to heat tar sands or cold viscous arctic collectors on the left side, which can be selectively accessible through the distribution substs (21) of the connecting chambers for supplying heated water to one or how close areas (1T, 1U, 1V, 1W, 1Y) to produce heated hydrocarbons from one or more of the remaining zones close.

Embodiments of the present invention, thus, provide a set of elements of combinable systems, devices and methods, which ensures the creation of any configuration or orientation of selectively controlled separate simultaneous flows of a fluid mixture with varying speeds in one or more underground wells that can depart from one main wellbore and wellhead equipment, for directing substantially hydrocarbons or a substantially fluid mixture of water-based liquids, gases, solids, or x combinations of at least one close zone of at least one passage through the subterranean formations, at least one more close zone or wellhead equipment, at or from the upper end of the underground well, with fluid flows mixtures can be pumped or recovered.
