Description

Technical Field

[0001] The invention relates to the technical field of oil field production, and more particularly to a dual-channel steady-flow water control regulator. Background Art

[0002] In the process of oilfield development, fine water injection is an important means to ensure the long-term stable production of oilfields, and to achieve it, the selection of water injection gates is one of the key means. There are many types of control gates used in existing oilfield water injection wells, most of which are not stable enough in water volume control, and often have phenomena such as springboard, water shrinkage, and stop injection, which seriously affects the normal water injection of oilfields.

[0003] Therefore, providing a dual-channel steady-flow water control regulator to control the injection volume of the injection well more reasonably and achieve fine water injection is a technical problem that needs to be urgently solved by those skilled in the art. Summary of the invention

[0004] In view of this, the present invention provides a dual-channel steady-flow water control regulator to solve the technical problem of unstable water volume control of existing water injection valves, so as to achieve more scientific control of the water injection volume of the water injection well.

[0005] The present invention adopts the following technical solution:

[0006] A dual-channel steady-flow water control regulator, characterized in that it includes a main valve body, a first regulating valve and a second regulating valve, the main valve body is provided with a first regulating valve accommodating chamber and a second regulating valve accommodating chamber arranged opposite to each other, the first regulating valve and the second regulating valve are respectively installed in the first regulating valve accommodating chamber and the second regulating valve accommodating chamber; an inlet channel, a first water outlet channel and a second water outlet channel are provided on the main valve body, the first regulating valve and the second regulating valve can be sealed or connected with the water outlet end of the inlet channel; the first regulating valve is connected with the water inlet end of the first water outlet channel, and the second regulating valve is connected with the water inlet end of the second water outlet channel.

[0007] It can be seen from the above technical scheme that, compared with the prior art, the present invention discloses a dual-channel steady-flow water-control regulator. When flushing an injection well, the first regulating valve is opened, and water enters the first regulating valve through the water inlet channel and flows out from the water outlet channel one, thereby completing the function of flushing the injection well; when fine water injection is performed, the first regulating valve is closed, and the second regulating valve is opened. By adjusting the second regulating valve, water enters the second regulating valve from the water inlet channel and flows out from the water outlet channel two, thereby completing the fine water injection of the injection well; when large-scale water injection is performed, the first regulating valve is opened, and a part of the water flows out from the water outlet channel one, and the other part of the water is controlled by the second control regulating valve and flows out from the water outlet channel two, thereby completing the fine water injection of the injection well.

[0008] Furthermore, the first regulating valve includes a valve body, a valve stem and a valve seat. The valve body is fixed to the inner wall of the first regulating valve accommodating chamber and has a water inlet hole thereon; the valve seat is fixed to the valve body and is located at one end where the first regulating valve accommodating chamber and the second regulating valve accommodating chamber are close to each other.

[0009] Among them, the valve body has a chamber 1 and a threaded hole 1 connecting the chamber 1 with the inside of the valve body 1, and the water inlet hole 1 connects the water inlet channel and the chamber 1; one end of the valve stem 1 passes through the threaded hole 1 and the chamber 1, and abuts against or separates from the valve seat 1 to seal or open the water inlet hole 1, and the valve stem 1 is threadedly connected to the threaded hole 1 at the corresponding position.

[0010] The beneficial effect of adopting the above further scheme is that water flows out from the water inlet channel through the first regulating valve and out of the water outlet channel 1, realizing the functions of well washing and large-volume water injection, and the valve stem 1 and the valve seat 1 can be against or separated, realizing the sealing effect between the valve stem 1 and the valve seat 1.

[0011] Furthermore, a sealing ring 1 is fixed on the valve seat 1, and the valve stem 1 can be against or separated from the sealing ring 1 to seal or open the blockage or communication between the water inlet channel and the chamber 1.

[0012] Further, the sealing ring is vulcanized on the valve seat.

[0013] The beneficial effect of adopting the above further scheme is that a better sealing effect is achieved when the first regulating valve is closed. Because the impact force of the water flow is large during water injection, the sealing ring is vulcanized on the valve seat, which ensures that the sealing ring will not be washed away by the water flow, further ensuring the sealing effect.

[0014] Furthermore, the second regulating valve includes a valve body 2, a valve stem 2 and a valve seat 2. The valve body 2 is fixed to the inner wall of the second regulating valve accommodating chamber and has a water inlet hole 2 thereon. The valve seat 2 is fixed to the valve body 2 and is located at one end where the first regulating valve accommodating chamber and the second regulating valve accommodating chamber are close to each other. The valve body 2 has a chamber 2 and a threaded hole 2 connecting the chamber 2 and the inside of the valve body 2. The water inlet hole 2

[0015] The water inlet channel and chamber 2 are connected; one end of the valve stem 2 passes through the threaded hole 2 and chamber 2, and abuts against or separates from the valve seat 2 to seal or open the water inlet hole 2, and the valve stem 2 is threadedly connected at the corresponding position of the threaded hole 2.

[0016] The beneficial effect of adopting the above further solution is that water flows out from the water inlet channel through the second regulating valve and out of the water outlet channel 2, thus realizing the function of fine water injection into the water injection well. Further, the sealing ring 2 is fixed on the valve seat 2, and the valve stem 2 can be against or separated from the sealing ring 2 to seal or open the water inlet channel and the chamber 2.

[0017] Further, the sealing ring is vulcanized on the valve seat 2.

[0018] The beneficial effect of adopting the above further scheme is that the sealing effect is ensured when the second regulating valve is closed, and because the impact force of the water flow is large during water injection, the sealing ring is vulcanized on the valve seat, which ensures that the sealing ring will not be washed away by the water flow, further ensuring the sealing effect.

[0019] Furthermore, the valve stem 2 is connected with an adjusting rod.

[0020] The beneficial effect of adopting the above further solution is that the regulating rod facilitates the adjustment of the second regulating valve and effectively controls the amount of water injected into the water injection well.

[0021] Furthermore, the materials of valve stem 1, valve seat 1, valve stem 2 and valve seat 2 are all 3Cr13.

[0022] The beneficial effect of adopting the above further solution is that it has stronger corrosion resistance and wear resistance and increases the service life.

[0023] Furthermore, the diameter of the water outlet channel 1 is greater than the diameter of the water outlet channel 2.

[0024] The beneficial effect of adopting the above further solution is that the requirements for the first water injection and the second water injection of the water injection well can be more reasonably met.

[0025] Furthermore, it also includes a water inlet pipe and a water outlet pipe, the water inlet pipe is connected to the water inlet end of the water inlet channel, and the water outlet pipes are connected to the water outlet end of the water outlet channel 1 and the water outlet end of the water outlet channel 2.
