Abstract
Description
Technical Field
[0001] This utility model relates to the field of booster water injection pump technology, and more specifically, to a fully enclosed oil well booster water injection pump. Background Technology
[0002] In oilfield extraction, as crude oil is continuously extracted, the underground formation pressure gradually decreases, which leads to poor crude oil fluidity and even makes it impossible to extract. To solve this problem, high-pressure water is injected into the oil layer to replenish the formation pressure and push the crude oil to flow towards the wellhead, thereby improving the crude oil recovery rate. The oil well booster water injection pump is the core equipment to achieve this process.
[0003] A search revealed that Chinese patent CN219345072U discloses a backflow prevention oilfield booster water injection pump. Through the arrangement of a linkage plate, a fixed leak plate, and a sealing plate, the flowing water impacts the linkage plate, causing it to move. This movement of the sealing plate, in turn, causes the sealing rod to flip and open the leak groove, allowing water to flow out through it. This prevents backflow without affecting the normal operation of the booster water injection pump.
[0004] When the aforementioned booster water injection pump is in use, it is equipped with a water outlet pipe. A fixed leak plate is fixedly installed on the inner wall of the water outlet pipe. A sealing structure is installed on the fixed leak plate, but the sealing is achieved only by a single sealing plate. Since the water injection medium in oil fields often contains crude oil residue, mud particles and high concentrations of minerals, when it flows through the contact surface between the sealing plate and the fixed leak plate for a long time, it will continuously scour the sealing contact area. The edge of the sealing plate is prone to small gaps due to wear, and the contact surface will also form irregular gaps due to impurities embedding, causing high-pressure water to slowly leak along the gaps. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a fully enclosed oil well booster water injection pump, which aims to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a fully enclosed oil well booster water injection pump, comprising a booster water injection pump body and two connecting pipes. The two connecting pipes are respectively fixedly connected to the input end and the output end of the booster water injection pump body. Each of the two connecting pipes has a collar fixedly connected to one of its opposite ends. Each of the two collars has two first sealing gaskets inside. Each of the two collars has two side plates fixedly connected to one of its facing sides. Each of the two connecting pipes is provided with a protective assembly. Each of the two protective assemblies includes two protective frames, two second sealing gaskets, two lead screws, and multiple nuts. The multiple protective frames are respectively movably sleeved on the two connecting pipes. One side of each of the multiple second sealing gaskets is fixedly connected to one of the two protective frames.
[0007] Furthermore, one end of each of the multiple lead screws passes through multiple protective frames and multiple side plates, and multiple nuts are movably sleeved on the multiple lead screws.
[0008] As can be seen, the above technical solution facilitates the fixing of the two protective frames.
[0009] Furthermore, a base is fixedly connected to the bottom end of the booster water pump body, wherein the base serves to facilitate support for the booster water pump body.
[0010] Furthermore, one of the connecting pipes is internally fixedly connected to an inner ring, and the inner ring is provided with an anti-backflow component, which includes a convex plate, a third sealing gasket, two side plates, two springs, two slide rods, and two limiting plates.
[0011] Furthermore, the third sealing gasket is fixedly sleeved on the convex plate, and the outer side of the third sealing gasket is in contact with the inner ring.
[0012] Furthermore, the two side plates are fixedly connected to the convex plate on opposite sides, and the two ends of the two springs are fixedly connected to the inner ring and the two side plates respectively.
[0013] Furthermore, one end of each of the two slide rods is fixedly connected to the inner ring, and the other end of each slide rod passes through the two side plates and the two springs respectively. One side of each of the two limiting plates is fixedly connected to the two slide rods respectively.
[0014] As can be seen, in the above technical solution, the two sliding rods can limit the two side plates to prevent them from deflecting, and the two limiting plates can limit the movement distance of the two side plates.
[0015] The technical effects and advantages of this utility model are as follows: 1. This utility model improves the sealing between the collar and the external pipe by using two first sealing gaskets, thereby effectively preventing high-pressure water leakage. Two protective frames are fitted onto the connecting pipe and the external pipe, and then the two protective frames are fixed together by two screw rods and multiple nuts. The connection between the connecting pipe and the external pipe is fully sealed by the two protective frames. The operation is simple and effectively improves the sealing between the connecting pipe and the external pipe. 2. In this utility model, the liquid in the connecting pipe squeezes the convex plate, causing the convex plate and the third sealing gasket to move away from the inner ring. At the same time, the convex plate drives the two side plates to move horizontally, thereby causing the two springs to stretch. When the liquid is stopped, the two springs rebound and drive the convex plate and the third sealing gasket to reset. The third sealing gasket can improve the sealing between the convex plate and the inner ring, preventing the outflowing liquid from entering the main body of the booster water pump. The structure is simple and can effectively prevent liquid backflow. Attached Figure Description

[0020] Refer to the instruction manual appendix Figure 1-3The fully enclosed oil well booster water injection pump of this embodiment includes a booster water injection pump body 1 and two connecting pipes 2. The two connecting pipes 2 are respectively fixedly connected to the input end and the output end of the booster water injection pump body 1. The opposite ends of the two connecting pipes 2 are each fixedly connected to a collar 5. The inside of the two collars 5 is provided with two first sealing gaskets 6. The opposite sides of the two collars 5 are each fixedly connected with two side plates 7. The two connecting pipes 2 are each provided with a protective component 4. The two protective components 4 each include two protective frames 401, two second sealing gaskets 402, two screw rods 403 and multiple nuts 404. The multiple protective frames 401 are respectively movably sleeved on the two connecting pipes 2. One side of the multiple second sealing gaskets 402 is respectively fixedly connected to the two protective frames 401.
[0021] Furthermore, one end of each of the multiple lead screws 403 passes through multiple protective frames 401 and multiple side plates 7, and multiple nuts 404 are movably sleeved on the multiple lead screws 403.
[0022] Furthermore, a base 3 is fixedly connected to the bottom end of the booster water pump body 1, wherein the base 3 serves to facilitate support for the booster water pump body 1.
[0023] Furthermore, one of the connecting pipes 2 is internally fixedly connected to an inner ring 8, and an anti-backflow component 9 is provided on the inner ring 8. The anti-backflow component 9 includes a convex plate 901, a third sealing gasket 902, two side plates 903, two springs 904, two sliding rods 905, and two limiting plates 906. The third sealing gasket 902 is fixedly sleeved on the convex plate 901, and the outer side of the third sealing gasket 902 is in contact with the inner ring 8. The two side plates 903 are fixedly connected to the convex plate 901 on opposite sides.

[0024] When the booster pump body 1 is working and conveying liquid, the liquid in the connecting pipe 2 squeezes the convex plate 901, causing the convex plate 901 and the third sealing gasket 902 to move away from the inner ring 8. The liquid passes through the inner ring 8 and enters the external pipe. At the same time, the convex plate 901 drives the two side plates 903 to move horizontally, thereby causing the two springs 904 to stretch. When the liquid is stopped, the two springs 904 rebound and drive the convex plate 901 and the third sealing gasket 902 to reset.

The structure is simple and can effectively prevent liquid backflow. The two sliding rods 905 can limit the two side plates 903 to prevent them from deflecting, and the two limiting plates 906 can limit the movement distance of the two side plates 903.
[0025] The usage method of this embodiment is as follows: In use, the external pipe is connected to the collar 5 with bolts.

The two protective frames 401 are fitted onto the connecting pipe 2 and the external pipe, and the two second sealing gaskets 402 can improve the sealing between the two protective frames 401, the connecting pipe 2 and the external pipe. Then, the two screw rods 403 are inserted into the two protective frames 401 and the two side plates 7 in sequence. Finally, the two screw rods 403 are limited by multiple nuts 404, thereby fixing the two protective frames 401 together. The two protective frames 401 provide full sealing protection for the connection between the connecting pipe 2 and the external pipe. The operation is simple and effectively improves the sealing between the connecting pipe 2 and the external pipe.
