Abstract

Apparatuses and methods to communicate with a zone below a subsurface safety valve (104. 204) independent of the position of a closure member (106) of the safety valve are disclosed. The apparatuses and methods include deploying a subsurface safety valve (104, 204) to a profile located within a string of production tubing. The subsurface safety valve (104, 204) is in communication with a surface station through an injection conduit (150,152;250,252) and includes a bypass pathway (144, 244) to inject various fluids to a zone below.

Description

METHOD AND APPARATUS FOR DEVIATING A WELL TOOL HYDRAULICALLY BACKGROUND OF THE INVENTION The present invention relates in general to subsurface devices used in the petroleum production industry. More particularly, the present invention relates to an apparatus and method for driving fluid through subsurface devices, such as a subsurface safety valve, to a location within the well. Even more particularly, the present invention relates to apparatuses and methods for installing a subsurface safety valve incorporating a bypass conduit that allows communications between a surface station and a lower zone independently of the operation of the safety valve. There are several obstructions in the columns of production pipes in underground well drilling. Valves, probe guides, closure plugs, seals, sliding side doors, flow control devices, expansion joints, connection / disconnection unions, male end connectors, dual termination components, and other recoverable termination pipe equipment they can build the deployment of columns- from capillary tubing to underground production zones. One or more of these types Ref .: 172774 of obstructions or tools are shown in the following U.S. Patents which are incorporated herein by reference: Young, 3,814,181; Pringle, 4,520,870; Carmody et al., 4,415,036; Pringle, 4,460,046; Mott, 3,763,933; Morris, 4,605,070; and Jackson et al., 4,144,937. Particularly, in circumstances where the stimulation operations have to be carried out in wells that do not produce hydrocarbons, the obstructions occur in the form of operations that are capable of obtaining a continuous production from a well that for a long time was considered exhausted. Most depleted wells are not depleted of hydrocarbon reserves, rather the natural pressure of the hydrocarbon production zone is so low that it fails to exceed the hydrostatic pressure or head of the production column. Frequently, secondary recovery operations and artificial lifting operations will be carried out to recover the remaining resources, but such operations are often very complex and expensive to be carried out in all wells. Fortunately, many new systems are enabled for the continuous production of hydrocarbons without secondary recovery and expensive artificial lifting mechanisms. Many of these systems use the periodic injection of various chemical substances within the production zone to stimulate the production zone, thus increasing the production of marketable quantities of oil and gas. However, obstructions in production wells often occur in the form of deployment of an injection conduit to the production zone in such a way that chemical stimulation substances can be injected. Although many of these obstructions are removable, they are typically components that are required to maintain well production in such a way that permanent removal is not feasible. Therefore, a mechanism to fix them would be quite desirable. The most common of these obstructions found in the production pipe columns are subsurface safety valves. Sub-surface safety valves are typically installed on pipe columns deployed in underground wellbores to prevent the escape of fluids from the wellbore to the surface. In the absence of subsurface safety valves, sudden pressure increases within the well can lead to disastrous explosions of fluids into the atmosphere. Therefore, numerous drilling and production regulations throughout the world require that safety valves be in place in the production pipe columns before certain operations are allowed to continue. Safety valves allow communication between isolated areas and the surface under regular conditions but are designed to close when undesirable conditions exist. A popular type of safety valve is commonly referred to as a surface-controlled subsurface safety valve (SCSSV, for its acronym in English) . SCSSVs typically include a closure member generally in the form of a circular or curved disc, a rotating ball, or a rod, which engages a corresponding valve seat to isolate areas located upstream and below the closure member in the subsurface well . The closure member is preferably constructed in such a way that the flow through the valve seat is as restricted as possible. Usually, SCSSVs are located within the production pipeline and isolate production zones of upper portions of the production pipeline. Optimally, the SCSSV function as high aperture check valves, because they allow substantially unrestricted flow therethrough when open and completely seal the flow in one direction when closed. In particular, production pipe safety valves prevent fluids from production areas from flowing up the production pipe when they close but still allow fluids (and tool movement) to flow into the production zone from the production zone. above.
SCSSVs usually have a control line that extends from the valve, that control line being placed in an annular space formed by the well tubing and the production tubing and extending from the surface. The pressure in the control lines opens the valve allowing the production or entry of tools through the valve. Any loss of pressure in the control line closes the valve, prohibiting the flow from the underground reservoir to the surface. The closure members are often energized with a displacement member (spring, hydraulic cylinder, gas charge and the like, as is well known in the industry) such that in a condition without pressure, the valve remains closed. In this closed position, any accumulation of pressure below in the production zone will push the closure member against the valve seat and will act to reinforce any seal between them. During use, the closure members open to allow free flow and displacement of production fluids and tools through them. Previously, to install a chemical injection duct around an obstruction of production pipeline, the entire production pipeline of the well had to be recovered and the injection conduit incorporated into the column before replacing it with a cost often of millions of dollars . This process is not only expensive but also time consuming, therefore it can only be done in wells that have sufficient production capacity to justify the expense. A simpler and less expensive solution would be well received in the oil production industry and would allow wells that have been abandoned for economic reasons to continue to operate.

BRIEF DESCRIPTION OF THE FIGURES Figure 1 is a sectional view of a fluid bypass assembly in accordance with an embodiment of the present invention wherein the fluid bypass path can be used with an industry-standard SCSSV. Figure 2 is a sectional view of a fluid bypass assembly in accordance with an alternative embodiment of the present invention wherein the fluid bypass path is integrated with. mounts e of the SCSSV. DETAILED DESCRIPTION OF THE INVENTION With initial reference to Figure 1, a fluid bypass assembly 100 is shown in accordance with one embodiment of the present invention. The bypass assembly 100 preferably runs inside a column of production line 102 and allows fluid to be diverted from a well tool 104. In figure 1, a well tool 104 is shown as a subsurface safety valve but someone With skill in the art it will be understood that any deployable pit tool in a pipe column can be similarly diverted using the apparatuses and methods of the present invention. However, the well tool 104 of Figure 1 is a subsurface safety valve that runs in line with the production line 102, and includes a fin disk 106, an operation mandrel 108, and a hydraulic control line 110. The fin disk 106 is preferably displaced in such a way that when the operating mandrel 108 of the internal diameter of a valve seat 112 is recovered, the disc 106 closes and prevents the fluids below the safety valve 104 from communicating with the valve 104. top of the hole. The control line 110 operates the operation mandrel 108 in and out of the engagement with the fin disk 106, thereby allowing a user on the surface to manipulate the state of the fin disk 106. In addition, the fluid bypass assembly 100 includes a lower anchor fishing platform 120 and an upper anchor fishing platform 122, each configured to receive and anchor seal assembly 124, 126. The upper anchor seal assemblies 126 and lower 124 are configured to engage in anchor fishing angles " 120, 122 and transmitting injected fluids through the well tool 104 with minimal obstruction of production fluids flowing through the perforation 114. The anchor seal assemblies 124, 126 include engaging members 128., 130 and seal plugs 132, 134. The latching members 128, 130 are configured to engage and be retained by the anchor fishing platforms 120, 122, which may include a latching profile. Although a modality is schematically shown for the engaging members 128, 130 and the corresponding anchor fishing platforms 120, 122, it should be understood that numerous systems are possible for engaging the anchor seal assemblies 124, 126 on anchor fishing platforms. 120, 122 without departing from the present invention. The seals of closure plugs 132, 134 are located on each side of the zones of the injection ports 136, 138 of the anchor seal assemblies 124, 126 and serve to isolate the zones of the injection ports 136, 138 of the production fluids 160 that travel through the internal diameter 114 of the well tool 104 and / or the internal diameter of the production pipe column 102. In addition, the injection port zones 136, 138 are in communication with the hydraulic ports 140, 142 in the circumferential wall of the fluid bypass assembly 100 and the hydraulic ports 140, 142 are in communication with each other through a hydraulic bypass path 144. The hydraulic ports 140, 142 may include a fluid communication path 141, 143 between an inner surface of the upper and lower anchor fishing docks 120, 122 and a respective internal chamber circumferentially spaced on each fishing platform Anchor. The hydraulic ports 140, 142 may include a plurality of fluid communication paths 141, 143. A hydraulic port 140, 142 may also directly communicate with the hydraulic bypass path 144 without. the internal chamber shown circumferentially spaced. The hydraulic bypass path 144 is shown schematically in Figure 1 as an external line connecting the hydraulic ports 140 and 142, but it should be understood that the hydraulic bypass path 144 may be either an interior of the path (not shown) of the body of bypass assembly 100 or an external conduit. Regardless of the internal or external construction, the hydraulic bypass path 144, the hydraulic ports 140, 142, and the closure plug seals 132, 134 allow the injection port 138 to communicate hydraulically with the port area of the port. injection 136 without contamination of the production fluids 160 flowing through the internal diameter 114 of the well tool 104 and / or the internal diameter of the production line 102. Additionally, one skilled in the art should understand that it can It is desired to use the production line 102 and the well tool 104 of the assembly 100 before the anchor seal assemblies 124, 126 are installed in the fishing sockets 120, 122. As such, any premature hydraulic communication around the well tool 102 between the hydraulic ports 140 and 142 through the hydraulic bypass path 144 could compromise the functionality of the well 104 and such communication would need to be avoided. Therefore, cutting shutters (not shown) can be located in hydraulic ports 140, 142 prior to deployment of the well tool 104 in the production line 102 to prevent the hydraulic bypass path 144 from permitting communication prior to what is desired The cutting shutters could be constructed to cut and expose the hydraulic ports 140 and 142 when the anchor seal assemblies 124, 126, or other device are engaged thereto. A lower column of injection conduit 150 is suspended from a lower anchor seal assembly 124 and an upper anchor seal assembly 126 is connected to an upper injection conduit column 152. Because the injection conduit 150 is in communication with the injection port area 136 of the lower anchor seal assembly 124 and the upper injection conduit 152 is in communication with the injection port region 138 of the upper anchor seal assembly 126, the fluids flow from the upper injection duct 152, through a hydraulic bypass path 144 to a lower injection duct 150. This communication can take place through an internal bypass path, shown as a dotted duct in Figure 1, either on either or both upper and lower anchor seal assemblies 126, 124. As such, by using the fluid bypass assembly 100, an operator can inject fluids below a well tool 104 independently of the condition or condition of the well tool 104. By using the fluid bypass assembly 100, the fluids can be injected (or recovered) after the well tools 104 that would otherwise render such communication impossible. For example, when the well tool 104 is a subsurface safety valve, injection can take place when the fin disk 106 is closed. To install the diverter assembly 100 of FIG. 1, the well tool 104, the fishmonger lower anchor 120 and the upper anchor fishing platform 122 are deployed into a hole in line with the column of the production line 102. Once installed, the well tool 104 can function as designed as far as the injection below is desired. of the well tool 104. Once desired, the lower anchor seal assembly 124 is lowered by the production line 102 until it reaches the well tool 104. Preferably, the bottom anchor seal assembly 124 is constructed in such a manner way that is capable of passing through the upper anchor fishing platform 122 and the inner diameter 114 of the well tool 104 without obstruction to the fishing anchor sockets and lower 120. Once the lower anchor seal assembly 124 reaches the bottom anchor fishing boom 120, it is hooked therein in such a manner that the seals of closure plugs 132 properly insulate the area of the injection port 136 that is in contact with the hydraulic port 140. With the lower anchor seal assembly 124 installed, the upper anchor seal assembly 126 is lowered by the production line 102 at an end remote from the upper injection conduit 152. Because the upper anchor seal assembly 126 need not pass through the internal diameter 114 of the well tool 104, it may be of greater geometry and configuration than the lower anchor seal assembly 124. With the upper anchor seal assembly 126 hooked on the upper anchor fishing platform 122, the sealing plug seals 134 isolate the area of the injection port 138 that is in contact with the hydraulic port 142. Once installed, communication between the upper injection conduit 152 and the lower injection conduit 150 through the hydraulic ports 142, 140, the injection port zones 138, 136, and the path of the injection can take place. hydraulic bypass 144. Optionally, a check valve 154 may be placed in the lower injection duct 150 to prevent production fluids 160 from flowing to the surface through the upper injection duct 152. A check valve may be placed in any section of the upper injection ducts 152 or lower 150 as well as the hydraulic bypass path 144. A check valve can be integrated in the upper or lower anchor seal assemblies 126, 124. Ports 156, 158 in the seal assemblies of lower and upper anchoring 124, 126 allow the flow of production fluids 160 to pass through them with minimal obstruction. Further, in circumstances where the well tool 104 is a device that would not allow the lower anchor seal assembly 124 to pass through the internal diameter 114 of a well tool 104, the lower anchor seal assembly 124 can installed before the production line 102 is installed in the well, leaving only the upper anchor seal assembly 126 to be installed after the production line 102 has been disposed in the well. Now with reference briefly to Figure 2, an alternative mode for an assembly deviation of fluid 200. The fluid bypass assembly 200 differs from the fluid bypass assembly 100 of Figure 1 because the assembly 20O is constructed of several threaded components in place of the unitary arrangement detailed in Figure 1. Particularly, a pipe column of Production 202 is connected to a well tool 204 through fishing anchor fittings 222, 220. The well tool 204 itself is constructed as an attachment with threaded connections 270, 272 at each end. The threaded connections 270, 272 allow varied configurations of the well tool 204 and the anchor fishing tackle 220, 222 to be constructed. For example, several well tools 204 can be placed in series to form a combination of tools. In addition, threaded connections 270, 272 allow more versatile and easy inventory management for remote locations, whereby an appropriate combination of anchoring fishing accessories 220, 222 and well tools 204 can be made for each particular well. Regardless of the configuration of the fluid bypass assembly 200, the hydraulic bypass path 244 connects the injection lines 250 and 252 through the hydraulic ports 240 and 242. Due to the modular arrangement of the fluid bypass assembly 200, it is more It is probable that a hydraulic bypass path 244 is an external conduit extending between anchoring fishing accessories 220, 222, but with greater complexity, it can still be constructed as an internal path, if desired. The main advantage derived from having a hydraulic bypass path 244 as an internal path of the fluid bypass assembly 200 is the reduced likelihood of damage from contact with the well bore, well fluids, or other obstructions during installation. An internal hydraulic bypass path (not shown) could be protected from such hazards by the bodies of the anchor fishing tackle 220, 222 and the well tool 204. FIG. 2 further shows an alternative top injection conduit 252A that can be deployed in the annular space between the production pipe column 202 and the well borehole. An alternate upper injection conduit 252A could be installed in place of the upper injection conduit 252 and could allow the injection of fluids into the area below the well tool 204 without the need for an upper anchor seal assembly 226. A conduit 252A upper injection could, extend up. the hydraulic port 242 from the surface and communicate directly with the hydraulic bypass path 244. Still, alternatively, the upper injection conduit 252A could be installed in addition to the upper injection conduit 252 to serve as a backup path for the lower injection conduit 250 in the case of failure of the upper injection conduit 252, the hydraulic port 242, or the upper anchor seal assembly 226. In addition, the upper injection alternative conduit 252A can communicate directly with the lower anchor seal assembly 224 a through hydraulic port 240 if desired. A check valve can be placed in any section of the upper injection ducts 252 or lower 250 as well as the hydraulic bypass path 244. A check valve can be integrated into the upper or lower anchor fishing accessory 222, 220. described numerous embodiments and alternatives of the invention.
