Technical Field
[0001] The utility model application relates to the technical field of water distributors, in particular to an underground multifunctional water distributor. Background Art
[0002] The downhole multifunctional water distributor is a special tool used in oilfield water injection wells. Its principle is based on fluid mechanics and control theory. Through precise design and adjustment, it can achieve precise control and distribution of liquid flow. Specifically, the water distributor introduces liquid through the pipeline system, and then uses valves, pumps or other control devices to distribute the liquid to different pipelines or equipment as needed.
[0003] In the process of oil extraction, in order to maintain the pressure of different oil layers, stratified water injection is often used. The water distributor is an important tool for stratified water injection, and its performance directly affects the water injection effect. However, during the use of existing water distributors, when the water injection is stopped, the water flow in the oil layer often flows back to the inside of the water pump, resulting in a decrease in the water injection effect and even damage to the equipment. Therefore, how to design a downhole multifunctional water distributor with a non-return function has become a problem that needs to be solved urgently in this field. Summary of the invention
[0004] In order to solve the problem that when water injection is stopped, the water flow in the oil layer often flows back to the inside of the water pump, resulting in a decrease in water injection effect and even damage to the equipment, the utility model provides a downhole multifunctional water distributor to solve the above problem.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A multifunctional underground water distributor comprises a water distributor body and a first water outlet, wherein the water distributor body is symmetrically provided with two first water outlets, a protective shell is fixed at the lower outer side of the water distributor body, and two third water outlets are symmetrically provided on the protective shell, a fixing ring is fixed at the bottom inner end of the protective shell, a spring is fixed on the fixing ring, a movable collar is fixed above the spring, and two second water outlets are symmetrically provided on the movable collar, and two horizontal plates are symmetrically fixed on the inner side of the movable collar, and the horizontal plates extend to the interior of the water distributor body through the first water outlets.
[0007] Furthermore, an upper sliding ring is slidably connected to the upper part of the water distributor body, and a lower sliding ring is slidably connected to the inner part of the water distributor body near the transverse plate, and cleaning belts are fixed to the upper sliding ring and the lower sliding ring.
[0008] Furthermore, connecting rings are fixed to the side surfaces of the two transverse plates, two connecting rods are symmetrically fixed to the bottom ends of the connecting rings, and a plurality of cleaning rings are fixed to the connecting rods.
[0009] Furthermore, the positions of the first water outlet, the second water outlet and the third water outlet correspond to each other, and the shapes of the first water outlet, the second water outlet and the third water outlet are squares with the same length and width.
[0010] Furthermore, a side of the cleaning belt close to the water distributor body is in contact with the inner wall of the water distributor body, and the cleaning belt is in a triangular shape.
[0011] Furthermore, a downwardly inclined surface is formed at the bottom end of each cleaning ring, and the length between each two cleaning rings is greater than the length of the first water outlet.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. In the utility model, a movable collar is installed on the outside of the water distributor body, and a spring and a fixed ring are arranged below the movable collar, so that when water is injected, the water pressure pushes the horizontal plate to press the movable collar downward, and the water flows through the overlapping opening of the first water outlet and the second water outlet. When the water injection is stopped, the spring rebounds, so that the first water outlet and the second water outlet are offset and closed to prevent backflow, thereby solving the problem that when the water injection is stopped, the water flow in the oil layer often flows back to the inside of the water pump.

DETAILED DESCRIPTION
[0021] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described below are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0022] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A downhole multifunctional water distributor comprises a water distributor body 1 and a first water outlet 2, two first water outlets 2 are symmetrically arranged on the water distributor body 1, a protective shell 8 is fixed at the lower outer side of the water distributor body 1, two third water outlets 9 are symmetrically provided on the protective shell 8, a fixing ring 3 is fixed at the bottom end of the inner part of the protective shell 8, a spring 4 is fixed on the fixing ring 3, a movable collar 5 is fixed above the spring 4, two second water outlets 6 are symmetrically provided on the movable collar 5, two horizontal plates 7 are symmetrically fixed on the inner side of the movable collar 5, the horizontal plate 7 extends to the inside of the water distributor body 1 through the first water outlet 2 to prevent water from the oil layer from flowing back into the inside of the water distributor body 1.
[0023] Specifically, the positions of the first water outlet 2, the second water outlet 6 and the third water outlet 9 correspond to each other, and the shapes of the first water outlet 2, the second water outlet 6 and the third water outlet 9 are squares with the same length and width, which facilitates the outflow of water and avoids the backflow of water in the oil layer.
[0024] As an optimization solution, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, an upper sliding ring 13 is slidably connected to the upper part of the water distributor body 1, and a lower sliding ring 14 is slidably connected to the inner part of the water distributor body 1 near the horizontal plate 7. A cleaning belt 15 is fixed to the upper sliding ring 13 and the lower sliding ring 14. The side of the cleaning belt 15 close to the water distributor body 1 is in contact with the inner wall of the water distributor body 1. The shape of the cleaning belt 15 is triangular, so that the cleaning belt 15 cleans the upper part of the water distributor body 1.
[0025] Specifically, connecting rings 10 are fixed on the sides of the two horizontal plates 7, and two connecting rods 12 are symmetrically fixed to the bottom of the connecting rings 10. A number of cleaning rings 11 are fixed on the connecting rods 12. Each cleaning ring 11 has a downward inclined surface at the bottom, and the length between every two cleaning rings 11 is greater than the length of the first water outlet 2, so that when the horizontal plate 7 moves, the cleaning ring 11 cleans the lower part of the inside of the water distributor body 1.
[0026] Working principle: When water enters the water distributor body 1, the pressure of the water flow pushes the horizontal plate 7 to move downward, and the horizontal plate 7 drives the movable collar 5 to move downward. At this time, the spring 4 is compressed and rebounds. When the movable collar 5 moves, the first water outlet 2 coincides with the second water outlet 6. At this time, the first water outlet 2, the second water outlet 6 and the third water outlet 9 coincide, so that the water flows out to the inside of the oil layer. At the same time, when the water flows, the pressure of the water flow pushes the inclined surface on the cleaning belt 15, so that the water flow drives the cleaning belt 15 to move, so that the cleaning belt 15 drives the upper The sliding ring 13 and the lower sliding ring 14 rotate inside the water distributor body 1, so that the cleaning belt 15 cleans the interior above the water distributor body 1. At the same time, when the horizontal plate 7 is pressed and moves downward, it drives the connecting ring 10 to move downward, so that the connecting ring 10 drives the connecting rod 12 to move downward, and the connecting rod 12 drives the cleaning ring 11 to move downward at the same time. When the water flow stops, the spring 4 resets and rebounds, so that the movable sleeve 5 moves upward. At this time, the first water outlet 2 and the second water outlet 6 are misaligned to prevent the water flow inside the oil layer from flowing back to the inside of the water distributor body 1.
