Description

Technical Field

[0001] The utility model relates to the technical field of water injection tools, in particular to a diversion water injector. Background Art

[0002] After an oil field is put into development, as the exploitation time increases, the energy of the oil layer itself will be continuously consumed, causing the oil layer pressure to drop continuously, underground crude oil to degas in large quantities, viscosity to increase, oil well production to be greatly reduced, and even stop spraying and production, resulting in a large amount of dead oil remaining underground that cannot be extracted. In order to make up for the underground deficit caused by the extraction of crude oil, maintain or increase the oil layer pressure, achieve high and stable production of the oil field, and obtain a higher recovery rate, water injection must be carried out into the oil layer.

[0003] For example, a diversion water injector with the authorization announcement number "CN202228057U" can realize the high-pressure water injection from directly impacting the bottom of the artificial well in the vertical direction to flowing from the casing wall to the bottom of the artificial well, reducing the impact force of high-pressure water injection on the bottom of the artificial well, protecting the bottom of the artificial well, ensuring efficient water injection, connecting with the water injection wellhead, realizing water injection of the hollow casing of the water injection well, and directly injecting water into the water well without using oil pipes, reducing the single well water injection cost and the inspection and pipe operation cost. However, the water outlet of this type of diversion water injector is completely blocked by the piston, and the water in the water outlet can only provide lateral power to the piston, and cannot lift the piston upward, which results in the water outlet being unable to discharge water, thereby reducing the working quality of the diversion water injector. At the same time, the limit position of the sealing ball of this type of diversion water injector cannot be moved, which results in the sealing ball only being able to detect a fixed water pressure, which results in the detection ball being unable to detect it when the water pressure changes, which increases the working limitations of the diversion water injector. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the water in the water outlet can only provide lateral power to the piston but cannot push the piston upward, which results in the water outlet being unable to discharge water, thereby reducing the working quality of the diversion water injector and the limit position of the sealing ball being unable to move, which results in the sealing ball being able to detect only a fixed water pressure, which results in the detection ball being unable to detect changes in the water pressure, which increases the working limitations of the diversion water injector, and thus a diversion water injector is proposed.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A diversion and water injection device is designed, including a pressure cap, the outer wall of the pressure cap is fixedly connected to a main body, a ball seat moving mechanism is arranged inside the main body, the outer wall of the main body is fixedly connected to a shell, a diversion and water injection mechanism is arranged inside the shell, a water inlet is processed on the surface of the main body, a cross bar is installed on the inner wall of the main body, and a pressure detector is installed on the surface of the cross bar.

[0007] Preferably, the ball seat moving mechanism includes a bent rod, the outer wall of the bent rod is slidably connected to the main body through a sliding groove, the outer wall of the bent rod is fixedly connected to the handle, the outer wall of the bent rod is fixedly connected to the circular ring, the outer wall of the circular ring is fixedly connected to two limit blocks, the outer walls of the two limit blocks are both fitted with a sealing ball, the outer wall of the bent rod is fixedly connected to two baffles, the surfaces of the two baffles are slidably connected to the main body, and sealing rings are installed on the surfaces of the baffles.

[0008] Preferably, the outer wall of the circular ring fits with the main body, and the outer walls of the two limit blocks fit with the main body.

[0009] Preferably, the diversion and water injection mechanism includes a first sliding rod and a second buffer plate, the outer wall of the first sliding rod is fixedly connected to the shell, the outer wall of the first sliding rod is slidably connected to the inclined block, the outer wall of the inclined block is slidably connected to the second sliding rod through a through hole, the outer wall of the second sliding rod is installed with a spring, one end of the spring is fixedly connected to the inclined block, the surface of the inclined block is installed with a first buffer plate, and the outer wall of the second buffer plate is fixedly connected to the shell.

[0010] Preferably, the other end of the spring is fixedly connected to the housing, and the outer walls of the first sliding rod and the second sliding rod are both fixedly connected to the main body.

[0011] Preferably, a conduit is installed on the surface of the main body, and the outer wall of the conduit is in contact with the first buffer plate.

[0012] The utility model provides a diversion water injector, which has the beneficial effect that: through the cooperation of the shell and the diversion water injection mechanism, the water in the main body pushes the first buffer plate outward, the first buffer plate drives the inclined block to move, and the inclined block simultaneously compresses the spring, and the water discharged from the main body falls through the surface of the inclined block. The above method reduces the impact force of high-pressure water on the oil well, so that the water can fall slowly, which improves the working quality of the diversion water injector.

[0013] Through the cooperation of the main body and the ball seat moving mechanism, the handle drives the bent rod to move, the bent rod drives the ring to move, and at the same time the bent rod drives the baffle to move. The surface of the baffle is processed with a sealing ring to prevent water from flowing out of the main body. The ring drives the limit block to move, and the limit block drives the sealing ball to move. After the sealing ball moves to a suitable height, water is injected into the lower end of the main body. The high-pressure water drives the sealing ball to move upward. When the sealing ball moves to a suitable position with a distance from the pressure detector, the sealing ball can contact the pressure detector when it is lifted. In the above method, water pressures of different intensities can be tested, which reduces the working limitations of the diversion water injector. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Working principle:

[0027] When it is necessary to use a diversion water injector to inject water into an oil well:

[0028] First, the main body 2 is clamped and fixed by the pressure cap 1. The above fixing method is consistent with the description in a diversion water injector with the authorization announcement number "CN202228057U". Then, water is injected into the water inlet 9 to allow the water to enter the main body 2, and then discharged from the main body 2 through the conduit 6. At the same time, the water in the main body 2 pushes the first buffer plate 505 outward, and the first buffer plate 505 drives the inclined block 502 to move. The inclined block 502 also compresses the spring 504. The water discharged from the main body 2 falls through the surface of the inclined block 502, which reduces the impact force of the high-pressure water on the oil well.

[0029] When it is necessary to measure the pressure of a water well:

[0030] The operator moves the handle 301, the handle 301 drives the curved rod 302 to move, the curved rod 302 drives the ring 303 to move, and at the same time the curved rod 302 drives the baffle 306 to move. The surface of the baffle 306 is processed with a sealing ring to prevent water from flowing out of the main body 2, the ring 303 drives the limit block 304 to move, and the limit block 304 drives the sealing ball 305 to move. After the sealing ball 305 moves to a suitable height, the friction force at the sealing ring on the surface of the baffle 306 self-locks the curved rod 302, and water is injected into the lower end of the main body 2. The high-pressure water drives the sealing ball 305 to move upward. When the sealing ball 305 moves to a suitable position with the pressure detector 8, so that the sealing ball 305 can contact the pressure detector 8 when it is lifted, the operator stops moving the handle 302. When the water pressure is large enough, after the sealing ball 305 contacts the pressure detector 8, the pressure detector 8 sends a signal to complete the water pressure detection work.
