[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 continue to drop, a large amount of underground crude oil to be degassed, the viscosity to increase, the oil well production to be greatly reduced, and even the spraying and production will stop, 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, the oil field must be injected with water.
[0003] At present, in production practice, water is directly injected into the formation when it is injected into the interior. If the pressure inside the oil field is large enough, crude oil will flow back into the equipment, which will not only cause a waste of resources, but also affect the subsequent use of the equipment.

In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0022] See also Figure 1-Figure 5 As shown, the embodiment of the utility model provides a sealed water distributor, and the water purification equipment includes the following solutions:
[0023] Specifically, it includes an upper joint 1, the bottom end of the upper joint 1 is fixedly connected to an upper connecting sleeve 2, the bottom end of the upper connecting sleeve 2 is fixedly connected to a middle connecting sleeve 3, the bottom end of the middle connecting sleeve 3 is fixedly connected to a lower connecting sleeve 4, the inner wall of the lower connecting sleeve 4 is fixedly connected to a straightening body 5, and also includes an upper fixed plate 6 and a lower fixed plate 7 fixedly connected to the inner wall of the middle connecting sleeve 3, a filter assembly for removing impurities from the water body is arranged between the upper fixed plate 6 and the lower fixed plate 7, the filter assembly includes a fixed cylinder 8 fixedly connected to the middle part of the upper surface of the lower fixed plate, a filter hole 9 is arranged on the upper end of the outer side of the fixed cylinder 8, and a filter hole 9 is arranged on the top of the inner wall of the fixed cylinder 8. A float 10 is installed, and a rotating cylinder 11 is fixedly connected to the bottom end of the float 10. A rotating disk 12 is fixedly connected to the outer side of the bottom end of the rotating cylinder 11. An elastic component for preventing water backflow is arranged between the lower surface of the rotating disk 12 and the bottom end of the fixed cylinder 8. A plurality of water holes 13 are opened on the lower fixed disk 7, and a water inlet 14 is opened in the middle of the upper fixed disk 6. The elastic component includes a reset spring 15 installed between the lower surface of the upper fixed disk 6 and the bottom end of the fixed cylinder 8. A telescopic rod 16 for limiting is arranged inside the reset spring 15. The diameter of the float 10 is the same as the diameter of the inner wall of the fixed cylinder 8.
[0024] The above technical solution drives the float 10 to move downward inside the fixed cylinder 8 through the pressure of water injection, and at the same time, the rotating disk 12 at the bottom of the rotating cylinder 11 moves downward synchronously and compresses the reset spring 15, so that the telescopic rod 16 that limits the reset spring 15 is shortened synchronously until the top of the float 10 is lower than the lowest end of the filter hole 9. At this time, the injected water is filtered through the filter hole 9, and then flows out from the water flow hole 13 on the lower fixed disk 7, and finally flows into the oil field from the straightening body 5 fixed inside the lower connecting sleeve 4. When the internal pressure of the oil field is large enough, the water injection is stopped. Due to the elasticity of the reset spring 15, there is no water pressure to restore the float 10 to its initial position. Since the diameter of the float 10 is the same as the inner wall diameter of the fixed cylinder 8, and the position of the float 10 is higher than the filter hole 9 at this time, the phenomenon of crude oil backflow is avoided.
[0025] Specifically, a cleaning disc 17 is fixedly connected to the outside of the rotating cylinder 11, and a plurality of brush heads 18 for cleaning the filter holes 9 are fixedly connected to the outside of the cleaning disc 17. A fixing column 19 is fixedly connected to the bottom end of the inside of the fixed cylinder 8, and a limiting column 20 is fixedly connected to the outside of the top of the fixing column 19. A slide rail 21 for the sliding of the limiting column 20 is provided on the inner wall of the rotating cylinder 11. An annular groove 22 is provided at the bottom end of the fixed cylinder 8, and a slider 23 is slidably connected inside the annular groove 22. The bottom ends of the reset spring 15 and the telescopic rod 16 are fixedly connected to the slider 23.
[0026] The above technical solution enables the limiting column 20 on the fixed column 19 to slide on the internal slide rail 21 of the rotating cylinder 11, so that when the float 10 is subjected to the water injection pressure and synchronously drives the rotating cylinder 11 to move downward, because the limiting column 20 on the fixed column 19 slides on the internal slide rail 21 of the rotating cylinder 11, the rotating cylinder 11 drives itself to rotate while moving downward, so that the return spring 15 and the telescopic rod 16 between the top of the slider 23 and the lower surface of the rotating disk 12 move downward and rotate synchronously, and drive the slider 23 to slide in the annular groove 22. At this time, the cleaning disk 17 outside the rotating cylinder 11 rotates while carrying the brush head 18 to clean the filter hole 9, thereby improving the practicality of the equipment.
[0027] Working principle: Before working, water source is injected from the upper joint 1. At this time, the water flow presses down the float 10 at the water inlet 14 in the upper connecting sleeve 2. When the water flow pressure is sufficient, it will drive the float 10 to move to the bottom in the fixed cylinder 8. At this time, the limit column 20 on the fixed column 19 will slide on the slide rail 21 inside the rotating cylinder 11, so that the rotating cylinder 11 moves down with the float 10 while driving itself to rotate. The reset spring 15 and the telescopic rod 16 between the top of the slider 23 and the lower surface of the rotating disk 12 move down and compress synchronously, while following the slider 23 inside the annular groove 22 to rotate in a circle with the fixed column 19 as the axis, thereby driving the rotating The cleaning disc 17 on the outside of the cylinder 11 rotates while cleaning the filter hole 9 with the brush head 18 until the top of the float 10 moves down to below the lowest filter hole 9. At this time, the injected water is filtered through the filter hole 9, and then flows out from the water flow hole 13 on the lower fixed plate 7, and finally flows into the oil field from the straightening body 5 fixed inside the lower connecting sleeve 4. When the pressure inside the oil field is large enough, the water injection is stopped. Due to the elasticity of the reset spring 15, the float 10 will return to its initial position without the pressure of the water flow. Since the diameter of the float 10 is the same as the diameter of the inner wall of the fixed cylinder 8, and the position of the float 10 is higher than the filter hole 9 at this time, the reflux of crude oil is avoided.
[0028] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
