Description

The utility model relates to the field of hydrocarbon production (oil, gas, condensate, etc.), including in multilayer fields and can be used in simultaneous-separate or alternate operation of several formations in a single production or injection well.

The well-known "downhole installation for regulating and cutting off the flow of medium", containing a housing with inlet and outlet openings, inside of which are placed a bellows, a rod, a shutter and a saddle (Patent No. 2194152, ЕВВ 43/12, 34/06, op. 10.12.2002 g .).

The disadvantage of the above installation is that the bellows is charged only at one specific design pressure and only on the surface when there is a stand for injection of gas under high pressure into the bellows chamber. However, it is not always possible to accurately calculate or select the required pressure for charging the valve in order to maintain the valve and the well as a whole in the optimum selected operating mode. In addition, you need a stand for charging the bellows chamber.

The closest technical solution is “Downhole installation for cutting and regulating the flow in the well with one or more layers”, containing tubing, one or more landing chambers, with removable valves placed in them, having a body with bypass channels, a lock and external seals (Patent No. 2291949, ЕВВ 34/06, op. 01.20.2007).

The control of the control device is carried out by transmitting a pressure pulse through a pulse tube. Since it is possible to pass an impulse tube with a small limited diameter (not more than 20-25 mm) into the well through the packer, and the wells have a significant depth (more than 1000 m), the magnitude and speed of the transmitted pressure impulse will decrease significantly with distance from the source of its excitation due to high hydraulic resistance.

In some cases, it is generally impossible to create sufficient pulse pressure to switch a hydraulically controlled device to any position of discrete regulation.

Known borehole chamber, consisting of a housing made of a carrier and a guide pipe, and a pocket, and the pocket and the carrier pipe are interconnected. (Patent No. 2260108, ЕВВ 23/02, op. June 10, 2004).

The disadvantage of the aforementioned borehole chamber is that it does not provide for supplying to the pocket, for example, through a separate hydraulic channel, a working agent for acting on a regulator controlled by creating and holding a predetermined pressure in the pocket.

The closest technical solution is the Shafirova well chamber for removable valves, consisting of a shirt, pocket with internal bores, landing surfaces and passage channels. (Patent No. 2292439, ЕВВ 23/03, 34/06, op. January 27, 2007)

The disadvantage of the aforementioned borehole chamber is that it does not provide for supplying to the pocket, for example, a separate hydraulic channel, a working agent of a predetermined pressure for real-time control of the operation of the regulator installed therein.

Known valve for regulating the flow, containing a hollow body with external grooves, one or more bypass and axial passage channels, valves with rods and bellows interconnected (Patent No. 2029073, ЕВВ 43/00, op. 02.20.1995,)

The disadvantage of the above valve is that the valve does not have a separate external hole and a channel connecting it to the cavity of the bellows chamber, through which it is possible to charge the bellows in a deep well remotely from the surface at a certain pressure.

The closest technical solution is a valve for well operation, including a housing with bypass channels, in which a rod with a shutter element is located. (Patent No. 2043483, ЕВВ 34/06, op. September 10, 1995, prototype).

The disadvantage of the above design is that it does not provide for the possibility of transmitting a predetermined pressure remotely from the surface directly to the valve and, accordingly, the absence of a direct effect on the rod located inside the valve with shutter elements in real time.

Our technical solution simplifies the implementation of technological work to regulate the well’s operation in real time, ensures the creation of a given pressure for the hydraulic regulator, provides for the regulation and selection of the well’s operating mode from the surface by supplying a working agent (from the surface) through the hydraulic channel to the bellows and / or piston chamber of the regulator, provides an increase in the efficiency of the well’s operation when determining the reliable and optimal mode of its operation you, namely, allows you to increase the overhaul life of the well, by reducing the number of cable work associated with frequent changes in regulators and repairs due to wire breaks, eliminates the need for a stand to charge the bellows chamber.

The landing device with a pocket 3, having at least one passage hole 4 and at least one bypass channel 5, is a borehole chamber 20 with a pocket 3 or tubing 1 with a pocket 3.

Pocket 3 is located inside the tubing 1 (Figure 4) or outside the tubing 1 (Figure 5), as well as inside or outside the borehole chamber 20 (Fig.6-7).

The passage openings 4 of the pocket 3 installed inside the tubing 1 or inside the borehole chamber 20 are aligned with the passage openings of the tubing 1 or the borehole chamber 20.

The passage opening 4 of the landing device with pocket 3 is additionally equipped with a sealing device 21, for example, stuffing box, or sealing sealing elements 21, for example, rubber cuffs or rubber filler, for example, in the form of rubber glue, and is also equipped with an adapter 22 or an adapter 22 made in a removable or fixed design (Figs. 4-7).

The downhole chamber 20 is additionally equipped with a connecting element 29 located coaxially with the through hole 4 of the jacket 23 or pocket 3, the connecting element 29 is made in the form of a pipe section with a constant or variable cross-section and is additionally provided with a thread (Fig. 6).

The regulator 6 is designed to cut off and / or regulate the volume of fluid produced or injected into the well in which at least one bypass channel 8 and one or more through holes, for example, 7 and 27 and at least one chamber of a given pressure, are made interacting with the locking device (Fig.7).

The controller 6 is made in a removable version when the pocket 3 is located inside the landing device, (Figs. 1-4, 6, 7) or in a fixed version when the pocket 3 is located outside the landing device (Figure 5).

The controller 6 in a removable or non-removable design is made integral or monolithic.

To fix the regulator 6 in the pocket 3, for example, in the pocket 3 of the borehole chamber 20 (Fig.6, 7), the regulator 6 is additionally equipped with a lock 36, for example, in the form of a latch or in the form of a collet (Fig.7, 8, 9).

When the regulator 6 is removable, it is installed in the pocket 3 of the landing device. To install or remove the regulator 6, a rope technique with a special rope tool is used, with which the regulator 6 is installed in the pocket 3 of the landing device by means of the gripping head 30 or the upper part, which is made with the possibility of engagement, and a collet 36 placed on the shank 31 or on the lower part of the regulator 6, it is securely held in pocket 3.

The gripping head 30 or the upper part of the regulator 6 and the shank 31 or the lower part of the regulator 6 are additionally equipped with at least one bypass channel 32 or 33, which serve to flow through them the flow of well fluid through the regulator 6 from the central (tubing tubing) to annulus or vice versa.

Remote control of the flow rate of the borehole fluid or injection of fluid into the well is carried out by changing the flow cross section of the bypass axial channel 37 in the shut-off device of the regulator 6 (Fig. 8, 9).

The through hole 7 and / or 27 in the regulator 6 serves to pass the working agent into the bellows 12 and / or piston 11 of the chamber.

If two pressure chambers are located in the regulator 6, for example, piston chambers 11 and bellows chambers 12 or two piston chambers 11, it is additionally equipped with a connecting channel 38 (Figure 10).

The sealing element 9 ensures the tightness of the connection when the working agent is fed through the hydraulic channel 10 into the bellows 12 and / or piston 11 of the chamber of the regulator 6.

The downhole installation is additionally equipped with a dividing ring 45, which is located on the regulator 6 between the sealing elements 9 and creates a rigid frame, preventing the passage hole 7 and / or 27 from being blocked by the sealing elements 9 (Figure 5). In addition, the spacer ring 45 increases the sealing effect of the sealing element 9, preventing its leakage when operating at high pressures, and performs the functions of a centralizer, i.e. creates the effect of a centered entry of the regulator 6 into the pocket 3, which leads to an increase in the wear resistance of the sealing elements 9. The spacer ring 45 is also designed to reduce hydraulic losses during the passage of the working agent into the passage hole 7 and / or 27.

The dividing ring 45 is made with a groove or hole, for example, patterned.

The hydraulic channel 10 is a tubular element of constant or variable cross-section, for example, a pipe, umbilical, etc., passing through the tubing, packer 14, disconnector 15, centralizer 17 or inside the tubing 1, packer 14, disconnector 15, centralizer 17, etc. . additional downhole equipment.

The hydraulic channel 10 hermetically connects the pressure head device 2 to the pocket 3 of the landing device. (Figs. 1-6).

The pressure line of high pressure is additionally equipped with a fitting and / or shut-off device 46 (Figure 1).

Downhole installation works as follows.

Example 1

The downhole installation is lowered into the well with production casing 47 for developing the formation with an interval of perforation 48. The tubing 1 together with the downhole chamber 20 with pocket 3 and a hydraulic channel 10 are lowered into the well. In this case, the regulator 6 is made, for example, in a removable design, is equipped with a gripping head 30 and a shank 31. The regulator 6 is located in the pocket 3 of the borehole chamber 20, which contains a bellows chamber 12.

The hydraulic channel 10 is hermetically connected via an adapter 22 to the through hole 4 of the pocket 3 of the borehole chamber 20.

At the wellhead, the hydraulic channel 10 is connected to a high-pressure device 2, through which a working agent is supplied and a predetermined pressure is created in the hydraulic channel 10. The working agent from the hydraulic channel 10 enters through a sealing device 21, an adapter or an adapter 22 installed in the through hole 4 pocket 3. From the through hole 4 of the pocket 3, the working agent at a given pressure enters the through hole 7 of the regulator 6, and then into the bellows chamber 12. Under the action of increasing claimed in bellows chamber 12, its elongation occurs, which leads to the movement of the rod 40 towards the seat 41 with the fitting. The movement of the rod 40 towards the seat 41 leads to a change in the clearance between the shutter 42 in the form of a ball and the seat 41 and, accordingly, to a change in the volume of the borehole fluid flowing through the axial bypass channel 37. Similarly, a change in pressure is carried out, if instead of a bellows chamber 12 a piston chamber 11 is used, then in the piston chamber 11 a change in the position of the piston 39 occurs. By gradually changing the pressure at the mouth in the high-pressure device 2 and, accordingly, in the hydraulic channel 10 and in the chamber specified pressure 11 or 12, change the diameter of the bypass axial channel 37 between the seat 41 and the shutter 42 in the regulator 6. Moreover, in real time by changing the diameter of the bypass axial channel 37 regulation ensures, volume well fluid flows through the bypass channels 8, 32 and 33 of the tube space to the tube or vice versa. Depending on how the set pressure of the working agent comes from the hydraulic channel 10, for example, spasmodically abruptly or slowly gradually, in the same degree (dependency), spasmodic or gradually uniform movement of the locking elements 39, 40, 42, 43 locking device. In the event of a significant excess of pressure in the bellows 12 or piston 11 chambers over the pressure of the by-pass well fluid, either the shut-off device will completely close, i.e. axial bypass channel 37, or its opening. By adjusting the degree of openness of the axial bypass channel 37 in the zone of the shut-off device, the volume of the by-pass well fluid is changed through the bypass channels 8, 32, 33 of the regulator 6. Since the regulator 6 is removable, it is periodically changed during operation of the well using cable technology in connection with its possible mechanical wear.

Thus, any pressure regulation on the surface of the high-pressure device 2 in the form of a pressure conduit with a shut-off device 46 and a fitting, or a fitting after the high-pressure device 2 in the hydraulic channel 10, i.e. in the piston 11 or bellows 12 chambers, it leads to the operation of the shut-off device and, accordingly, to increase or decrease the flow of the borehole fluid through the bypass channels 33, 32, 8, which allows you to remotely adjust the operating mode of the well in real time on the surface.

Example 2

A downhole installation with a fixed controller 6 is lowered into the well with production casing 47 to develop a formation with an interval of perforation 48.

The tubing 1 together with the landing device with a pocket 3 and a hydraulic channel 10 are lowered into the well, while the regulator 6 is made in a fixed design. The regulator 6 is located in the pocket 3 of the tubing 1, which contains a piston chamber 11.

At the wellhead, the hydraulic channel 10 is connected to the high-pressure device 2 in the form of a pressure conduit with a shut-off device 46 and a fitting, by which a working agent is supplied and a predetermined pressure is created in the hydraulic channel 10. The working agent from the hydraulic channel 10 enters through the sealing device 21, for example, a stuffing box with a locking element installed in the passage hole 4 of the pocket 3 in the regulator 6 through the passage hole 7, and then into the piston chamber 11.

By the action of a predetermined high pressure on the piston 39, the rod 40 is moved, which leads to the shutter 43 moving to a predetermined position and, accordingly, to reducing or increasing the clearance between the shutter 43 and the seat 41, whereby the well operating mode is regulated.

Thus, the working agent, getting into the through holes 4 and 7, and then into the piston chamber 11, acts on the shut-off devices that control the flow of the borehole fluid passing through the bypass channels 8, 32 and 33. Since regulation is carried out remotely from the surface in the mode real time, then the well operation is also controlled on-line

Example 3

The downhole installation is lowered into the well with production casing 47 to develop the formation with an interval of perforation 48.

The tubing 1 together with the landing device with a pocket 3 and a hydraulic channel 10 is lowered into the well. In this case, the regulator 6, made in a removable design, is equipped with a gripping head 30 and a shank 31. The regulator 6 is located in the pocket 3 of the borehole chamber 20, which contains a bellows chamber 12 and a piston chamber 11.

The hydraulic channel 10 is hermetically connected by an adapter 22 to the through hole 4 of the pocket 3.

At the wellhead, a hydraulic channel 10 is connected to a high-pressure device 2, through which a working agent is supplied and a predetermined pressure is created in the hydraulic channel 10. The working agent from the hydraulic channel 10 enters through the sealing device 21, an adapter 22 installed in the through hole 4 of the pocket 3.

From the through hole 4 of the pocket 3, the working agent under a given pressure enters the through hole 7 of the regulator 6, and then into the bellows chamber 12, and also through the connecting channel 26 into the through hole 27 of the regulator 6, and then into the piston chamber 11.

Under the action of increasing pressure in the bellows chamber 12, it is elongated, which leads to the movement of the stem 40 towards the seat 41 with a fitting. The movement of the rod 40 towards the seat 41 leads to a change in the clearance between the shutter 42 in the form of a ball and the seat 41 and, accordingly, to a change in the volume of the borehole fluid flowing through the axial bypass channel 37. Similarly, the pressure in the piston chamber 11 is changed, which changes the position of the piston 39. Due to the gradual change in pressure at the wellhead in the pressure head device 2 and, accordingly, in the hydraulic channel 10, respectively, in the chambers of the set pressure 11 and 12, the diameter of the axial bypass is regulated channel 37 between the seat 41 and the shutter 42. In this case, in real time, by changing the diameter of the bypass axial channel 37, the volume of the flowing well fluid through the overflow is regulated sknye channels 8, 32 and 33 of the tube space into the annulus, or vice versa. Depending on how the pressure of the working agent comes from the hydraulic channel 10, for example, spasmodically abruptly or slowly gradually, an abrupt or gradually uniform movement of the shut-off elements 39, 40, 42, 43 will be noted. locking device. In the event of a significant excess of pressure in the bellows 12 and piston 11 chambers over the pressure of the bypass well fluid, either the shut-off device is completely closed, i.e. axial bypass channel 37, or its opening. By adjusting the degree of openness of the axial bypass channel 37 in the zone of the shut-off device, we seek to control the volume of the by-pass well fluid through the bypass channels 8, 32, 33 of the controller 6.

The proposed downhole installation of Garipov provides a supply of the working agent of a given pressure remotely from the surface of the well in various pressure change modes, as a result of which it becomes possible in real time to gradually produce continuously or smoothly-stepwise control of the flow rate or injection of the well.
