Description

The proposed technical solution relates to the oil industry, in particular to field development systems at the initial stage of development.

The newly developed fields are characterized by a significant remoteness from the inhabited areas, hard-to-reach conditions with an underdeveloped economy and infrastructure. The development of deposits at early stages is associated with high geological risks associated with the revaluation of reserves, therefore, the development of a development project is especially acute, taking into account the adaptation of technologies to changing operating conditions and minimizing the risks of unjustified costs for the construction of traditional capital facilities. The solution for the rapid commissioning of a field in conditions of uncertainty and the production of marketable oil is the use of a mobile oil treatment unit in early production technology (hereinafter referred to as the Mobile Unit). The use of a mobile unit makes it possible to reduce the time for commissioning a field, due to rapid design and manufacture based on unified technological blocks, due to simplified logistics, due to the use of container-type self-supporting load-bearing frames, due to the prompt execution of installation supervision and commissioning. During the further operation of the mobile unit, it is possible to introduce equipment in turn as it is actually needed with a point expansion of unified and interchangeable production lines with new units, from an early production unit to a modular oil treatment unit.

A mobile unit for preparing intermediate layers of an oily liquid is known (patent RU 2680601 C1, IPC C10G 33/04, C10G 33/06, publ. finished oil tank, heavy water tank (aqueous phase of oil product), oil sludge tank, heat exchangers, demulsifier dosing system, flocculant dosing system, nitrogen station, pumps, filters, characterized in that the said equipment is placed in two tiers in containers, designed for processing oil sludge of the installation field treatment of oil (UPPN) for the separation of persistent water-oil emulsions of intermediate layers accumulated in the VST, as well as periodic processing of oil-containing liquid phases of oil storage pits. The design of a mobile unit for preparing intermediate layers of an oily liquid is made in the form of several containers with the necessary equipment located inside. Containers are placed in two tiers to ensure unhindered joint operation of all units of equipment and ensure their rigidity during transportation to the territory of the UPPN. The technical result achieved by using this invention is to reduce the amount of oil sludge in the storage pits without taking it out of the field oil treatment plant (OCTP), as well as to increase the efficiency of the use of intermittent equipment designed to separate persistent water-oil emulsions of intermediate layers . This setup has the following disadvantages:

- as shown (in Fig. 1 of the patent), the six containers included in the installation have different overall dimensions, which does not ensure the rigidity of the entire two-story structure, so the base of the container No. 2 does not fall on the ribs of the containers of the lower tier Nos. 1 and 5;

- in order to lift container No. 3 to the second tier, a special traverse and a work permit for lifting oversized cargo will be required;

- to ensure the strength of fastening containers Nos. 2 and 3 to each other and to the containers of the lower tier Nos. 1 and 5, special lugs and clamps will be required;

- container #3 configuration disturbs the balance of the center of gravity on any vehicle during logistics operations.

A mobile plant for processing emulsion intermediate layers of well products is known (RU 2721518 C1 IPC B01D 17/00 C10G 31/10, publ. layers and bringing oil and formation water to the required quality group. The mobile unit for processing stable emulsion intermediate layers and preparing formation water consists of 4 technological container blocks 1, 2, 3, 4. Each of the container blocks is placed on one or more vehicles, which make it possible to move them by any mode of transport. The versatility of the mobile unit lies in the fact that at the OPF it can be used either for the preparation of commercial oil and formation water at the same time, or for the preparation of only commercial oil, or only for the preparation of formation water. The disadvantages of this analogue include:

- the impossibility of autonomous use, it is required to connect the technological and power equipment of the existing UKPN to existing communications,

- the impossibility of a tiered layout due to different dimensions of the blocks.

The closest in technical essence is (utility model patent RU 112642 U1 IPC B01D 19/00, publ. 01/20/2012) a mobile oil separation and pumping complex containing a separation and measuring unit, including an inlet separator, a hydrocyclone installed at the input of well production into the separator, a flow meter on the liquid line, a pump unit containing at least one pump, a control unit and drainage lines, according to the utility model, is equipped with a drainage tank with a submersible pump communicated with the inlet separator by means of drainage lines, while the inlet separator hydrocyclone has separate outlets for liquid and gas, and an ejector and a gas flow sensor are installed in the separation and measuring unit on the gas line, in addition, it is equipped with a condensate collection tank and a flare management unit, including an ignition unit, a torch, a torch control unit and a flare separator, communicated with a condensate collection tank, and the pump unit contains a flow meter, with e The blocks are interconnected by interblock technological lines. The disadvantages of this complex include the following:

- technological units are installed on a toboggan base, which prevents the implementation of logistics operations on public roads;

- the condensate collection tank and the drainage tank are made underground, which leads to additional costs during the arrangement and the essence of mobility is lost.

The purpose of the claimed invention is to create an installation that provides a quick launch of field development projects with high geological uncertainty at the initial stages of development, with simultaneous production and shipment of early oil, as well as increasing the mobility and manufacturability of the installation in order to optimize mechanized loading and unloading operations, operational movement all types of transport and manufacturability of installation at oil production facilities in the early stages of field development.

The goal is achieved by a mobile oil treatment unit in the early production technology, which is made in the form of separate technological units interconnected by pipeline and cable systems, including a first-stage separator unit, a chemical dosing unit, a well product heating unit, a drainage system, a flare unit, a automatic loading of oil, a block of pumps for a drainage system, a block of control and measuring equipment, while the frames of technological blocks are made with the dimensions of cargo containers according to ISO 668:1995 and equipped with upper and lower corner fittings in accordance with GOST 20527. The mobile unit additionally contains an inlet manifold block, a preparation block fuel gas, a three-phase separator block, an oil buffer tank block, a water buffer tank block, a block complete transformer substation with a low-voltage complete device.

The mobile unit consists of process units combined into a single complex to perform the following operations: oil degassing, oil treatment to standard quality levels, formation water treatment to the requirements of OST 39-225-88, preparation of fuel gas from associated petroleum gas for the well production heating unit , disposal of residual associated petroleum gas at a horizontal flare unit, automated loading of oil (or water) into tank trucks.

The equipment for the technological process of oil preparation is a set of capacitive equipment. In a mobile oil treatment plant, the tanks are configured in two types:

- tanks operating under pressure, made in the form of a horizontally elongated cylindrical volume with smoothly convex end parts (elliptical bottoms), together with the support and fastening system, forming a spatial structure in the dimensions of a standard 40-foot container (the design solution is protected by a patent). Such vessels are the First Stage Separator Unit (SPS) and the Three-Phase Separator Unit (TPS),

- buffer tanks each with a volume of 40 m ³ (Oil Sediment Block - BEN, Produced Water Sediment Block - BEV) and drainage tank (Drainage Collection Unit ED) have the shape of a parallelepiped with flat bottoms mounted in a rectangular frame with dimensions of a 40-foot container.

In the separation tank of the first separation stage (SPS Unit) two main functions are performed:

- degassing of the fluid coming from the wells together with associated petroleum gas fluid;

- separation of solid suspended particles from the fluid (sedimentation of sand under the action of gravitational forces, carried out from the wells together with the gas-liquid mixture).

For the efficient performance of these operations, the separator is equipped with an inlet cyclone unit, in which, due to centrifugal forces, an intensive release of gas from the liquid occurs, and also on the internal devices of the separator, a uniform distribution of the gas-liquid mixture coming from the wells is ensured, its pulsations are reduced, intensive selection of associated petroleum gas, separated from the fluid. The capacity of the SPS Block is released from the trapped solid phase periodically from the lower part of the separator to mobile pumping facilities.

The separator of the second stage of separation (Block TFS) is equipped with special coalescing devices. Packages of coalescing devices, designed using hydrodynamic simulation programs, provide intensification of the process of separating the emulsion into oil and formation water. Simultaneously, with the process of coalescence of formation water droplets, there is an additional release of dissolved petroleum gas from oil.

To prevent the entrainment of fine particles of light hydrocarbon fractions with the gas, the separation tank of the first separation stage and the three-phase separator are equipped with drop eliminators at the gas outlet.

In addition to capacitive units, the Mobile Unit includes units that provide the technological process of preparation.

The inlet manifold block (BG) is designed to connect the flow lines from producing oil wells to one collection manifold, from which the well fluid enters the process equipment of the installation. BG is mounted on the frame frame of a 10-foot container, it includes shut-off and control valves, a metering manifold and instrumentation.

Reagent Dosing Unit (RDU) is designed for receiving, storing and automated continuous dosed supply of liquid demulsifiers to the inlet of the separator of the first separation stage (SPS Unit) to increase the efficiency of well fluid separation into gaseous and liquid phases. Inside the BDR Block there is a closed rectangular four cubic capacity, equipped with a breathing pipeline and a breathing valve that maintains an overpressure of 2.5 MPa, from which the reagent is supplied to the separator by a dosing pump of the ND brand. The equipment of the stand-alone Block BDR is made in an explosion-proof design and placed in a frame with dimensions of a 20-foot container.

The fuel gas treatment unit (BPTG) is designed to treat associated petroleum gas (high-pressure gas), separated from the well fluid in the separator of the first separation stage (SPS Unit), before it is fed into the gas-using equipment of the Mobile Unit (as flue gas for the emulsion heating furnace, or, in the absence of a centralized power supply, for a gas piston power plant and other power equipment). Gas treatment in BPTG includes: a) gas purification from mechanical impurities and dropping liquid, b) reduction and maintenance of gas pressure at a given level at the outlet. BPTG consists of a complex of technological equipment: - centrifugal-vortex separator; - gas heating unit; - gas pressure reducing unit. The equipment of the Fuel Gas Preparation Unit is located in an insulated module in the dimensions of a 20-foot container.

The block of the system for measuring the amount of gas (SICG) is designed to carry out automated measurement of the parameters of the flow of flue gas prepared in the BPTG by flow, pressure, temperature sensors, as well as measurement of gas flow by volumetric vortex meters. SICG process measuring equipment is equipped with special gas filters and shut-off valves for gas pipelines. In addition to measuring and accounting for the amount of associated petroleum gas in the SICG, a separate line records and measures the dissolved gas released from oil (low pressure gas). Dissolved gas is formed in the separator of the second separation stage (TFS), the oil sedimentation tank (BEN) and in the water sedimentation tank (BEV). The total value of the amount of associated petroleum gas and the amount of released gas provides information on the total GOR of the production wells. From the SICG, the flue gas is sent to the Well Production Heating Unit (BNSP), the dissolved gas is sent for utilization to the horizontal flare unit (HFU). The SICG block is mounted in a frame with dimensions of a 20-foot container.

To ensure high efficiency at low energy consumption, the BNSP Block used a combined method of heating an oil-water emulsion with an intermediate coolant. The well product heating unit (BNSP) is a design of a heater with an intermediate coolant, characterized by the following composition of elements:

- placement of the flame tube horizontally under the coil;

- the implementation of the coil, in which the heated oil-water emulsion is circulated by pipe gas and the placement of the coil inside the tank in the medium of the intermediate coolant;

- placement of the burner and fan on one side of the container in the form of a parallelepiped, on the other side - a chimney;

- placing at the end of the tank, from the side opposite to the burner and flue elements of the flame tube, an armature assembly for connecting the heater coil to the outlet pipeline from the separator of the first separation stage and to the inlet pipeline to the three-phase separator;

- fulfillment of full factory readiness in the dimensions of a standard 40-foot container.

The operating parameters of the BNSP Unit are regulated and controlled by devices and automation tools that are part of the integrated local control system for the technological parameters of the Well Product Heating Unit (the external appearance is protected by a patent for industrial design 126656, patent holder of OILTEAM Engineering LLC).

The horizontal flare unit (HFU) includes the main horizontal gas burner, a standby gas burner with an igniter, a protective screen, gas supply pipelines for combustion. The presence of a flame on the pilot burner is controlled by a sensor. The signal about the extinction of the flame is transmitted to the control room. The design of the burner device is calculated in such a way as to provide a sufficient injection of atmospheric air for smokeless combustion. The HFC is placed in a flare embankment in an open way at a safe distance from all objects of the mobile plant. The embankment and HFU control cabinets are equipped with fences to prevent unauthorized access.

From the three-phase separator of the TFS Block, oil with a residual water cut of up to 10% (with the possibility of dehydration up to 0.5%) is sent through the pipeline for sedimentation to the Oil Buffer Tank Block (BEN) with a volume of V = 40 m ³ , in which at a pressure of 0.005 MPa and at a temperature of 80°C, residual degassing of dehydrated oil occurs. The oil settling unit is connected by a pipeline to the Automated Loading Unit.

The automated oil loading unit (BMN) is a two-tier monoblock (the external view is protected by a patent for an industrial design 118638, the patent holder is OILTEAM Engineering LLC). The oil loading unit is characterized by the following features:

- compositional division into two functional parts;

- the lower part of the monoblock, which is a complex for the commercial release of oil, which includes technological equipment: a pump module with a gear pump, an axisymmetric valve, a pressure pipeline, a metering unit for shipped oil, with an installed cariolis flow meter (mass meter), an electronics cabinet that provides control of filling into a tanker truck with shutting off the flow and stopping the pump according to two parameters: by the level of oil in the tanker truck; according to the total consumption of poured oil by the flowmeter;

- the upper part with technological equipment, which includes: a filling stand with a cover for the mouth of the tanker tank, which ensures the tightness of the filling, a changeover ladder, a ladder. The BMN block is mounted in a frame with dimensions of a 20-foot container.

The water buffer tank unit (BEV) with the volume of a rectangular tank V=40 m ³ is intended for additional sedimentation of produced water. The water level in the tank is determined by a level gauge (up to 80% filling). To prevent freezing, the tank is provided with a heater coil with supply and removal of heat carrier (steam from the PPU1600/100 field steam plant). BEV is placed in a block with dimensions of a 40-foot container.

To collect oil residues released during water settling, the BEV is connected by a pipeline to the drainage tank of the Drainage Collection Unit (ED). Unit ED is a rectangular non-pressure tank with a volume of V=40 m ³ placed in a frame with dimensions of a 40-foot container.

At the stage of early field development, as a rule, there is no reservoir pressure maintenance system with high-pressure water conduits for injection of reservoir water into the reservoir, therefore, the mobile unit provides for the possibility of supplying settled reservoir water to the inlet of the pumping unit of the Automated Oil Loading Unit (BMN) for further shipment to tank trucks for the purpose of removal and disposal at third-party facilities.

To supply settled formation water for shipment to the BMN from the buffer tank of the BEV Block, water is supplied through the pipeline to the inlet of the pumping units of the Drainage Pump Block (BND). At the inlet of pumping units, mechanical impurities are removed by means of inlet filters. On the discharge pipeline of the pumps, pressure is monitored by sensors that issue a signal to stop the pumping unit when the pressure limits in the discharge pipeline are reached.

The pressure pipeline of the Drainage Pump Unit (DPU) is connected by a pipeline to the Operational Water Metering Unit (BUOV), which houses shut-off and control valves and a flow meter for volumetric measurement of pumped formation water.

Blocks BND and BUOV are autonomous and placed in frames of blocks with dimensions of 10-foot containers.

The control of the technological process of oil treatment at a mobile unit is carried out using signaling and blocking systems that are part of the integrated automated control system for automated process control systems. The list of interlocks and alarms includes the following indicators of process control: - pressure; - temperature; - liquid level; - gas contamination. All information about the operation of the technological complex is sent to the control panel in the control room, located in the frame of the block with the dimensions of a 40-foot container. An automated control system with a distributed structure for collecting and processing information provides centralized hierarchical control and management, with the implementation of equipment self-diagnosis (Certificate of state registration of a computer program No. 2020614589, copyright holder of OILTEAM Engineering LLC).

All blocks are interconnected by pipeline and cable systems. Pipelines and cable lines are located on pre-fabricated modular communication corridors, using quick disconnect connections (pipe and electric couplers).

Each technological block, i.e. technological equipment of a single functionality is made within the boundaries of the unit in 100% factory readiness. Such execution of blocks in the conditions of a significant change in the properties of products allows for operational reengineering of the layout of technological blocks, and when expanding the capacity of the infrastructure, tiered placement of blocks is expected without performing construction and installation work to expand the production site.

The power supply of the mobile installation is carried out from a block complete transformer substation with a low-voltage complete device (KTP NKU), located in a block with dimensions of a 40-foot container.

Oil preparation using a dried mobile unit is carried out as follows:

The well fluid (oil-water-gas mixture) through pipeline I from production wells enters the inlet manifold block 1 (BG), is measured and combined into one reservoir, the incoming fluid from 1 (BG) is sent to the First Stage Separator Unit 2 (SPS), which is a separator the first stage of separation, in which fluid degassing takes place, and solid suspended particles are removed, in the form of sand, carried out of the well with the fluid flow. At the same time, a demulsifier is supplied to the inlet of the separator 2 (SPS) from the Reagent Dosing Unit 3 (BDR) via pipeline VII to ensure an efficient process of separating the liquid and gas phases of the fluid. At the outlet of the first stage separator 2 (SPS), two products are obtained - free associated petroleum gas of high pressure (APG) (pipeline IV) and water-oil emulsion (WOE) (pipeline II). APG is sent to Fuel Gas Treatment Unit 4 (BPTG), where it is cleaned and dried. The prepared gas (the so-called flue gas) is sent through pipeline IV of 4 (BPTG) to the Gas Quantity Measurement System Unit 5 (SICG), where, after measuring its amount, it is sent to the Well Production Heating Unit 6 (BNSP). At the same time, from the first stage separator 2 (SPS) to 6 (BNSP) through pipeline II, a water-oil emulsion of VNE is supplied. Heated to a predetermined temperature, WHE from 6 (BNSP) enters the three-phase separator of the second separation stage 7 (TFS). At the outlet of 7 (TPS), three products are obtained: commercial oil (pipeline III), formation water (pipeline IV) and low-pressure dissolved gas released from oil (pipeline V). Marketable oil through pipeline III enters the settling tank of the Oil Buffer Tank Block 8 (BEN), formation water enters the settling tank of the Water Buffer Tank Block 9 (BEV), low-pressure gas is sent to account for its amount in 5 (SICG). From Block 8 (BEN), marketable oil is sent via pipeline III to Automatic Oil Loading Block 10 (BMN), where commercial accounting is performed, and oil is shipped to oil carriers through the top loading system. In the process of oil settling in 8 (BEN), a residual separation of oil and water occurs and water accumulates at the bottom of the tank, which is discharged to the Produced Water Settling Unit 9 (BEV) through pipeline VI. At the same time, during the settling process, dissolved gas continues to be released from the oil, which is discharged through pipeline V from tank 8 (BEN) and sent through pipeline V to 5 (SICG). During the sedimentation of formation water in 9 (BEV), the release of oil residues continues, which forms on the surface of the water in the form of a film. Dissolved gas continues to be released from this remaining film of oil. The resulting gas is discharged into pipeline V and sent for accounting in 5 (SICG). And the oil residues from the water surface are removed to the Drainage Water Collection Unit 11 (ED), for subsequent shipment to tank trucks and removal to a centralized sludge collection pit. The entire volume of dissolved gas formed in blocks 7 (TFS), 8 (BEN), 9 (BEV) is sent to a separate line of block 5 (SICG) to account for its amount. The metered low-pressure gas from unit 5 (SICG) is sent for utilization (burning) to horizontal flare unit 12 (HFU). For the shipment of accumulated formation water, a system for its pumping and removal is provided. From the Sediment Block 9 (BEV), formation water is sent through pipeline VI to the Drainage System Pump Block 13 (BND), the pressure pipeline of the water pumps is connected to the Operational Water Accounting Block 14 (BUOV). Further, formation water is supplied through pipeline VI to the Automated Oil Loading Unit 10 (BMN) for shipment to tank trucks.
