Description

Technical Field

[0001] The utility model belongs to the technical field of water distributors, and in particular relates to a downhole water injection distributor. Background Art

[0002] Water distributor is a special downhole tool used to quantitatively inject water into each oil layer during stratified water injection. At present, the main defects of water distributor are as follows:

[0003] During the use of traditional water distributors, when the water pipe discharges water outward through the water outlet holes, the water still contains some impurities, and the traditional water distributor is unable to effectively disassemble the filtering structure for further cleaning after filtering, thereby reducing the service life of the entire water distributor. Utility Model Content

[0004] The purpose of the utility model is to provide a downhole water injection distributor, aiming to solve the problem in the prior art that the structure used for filtering can no longer be effectively disassembled for further cleaning after filtering, thereby reducing the service life of the overall water distributor.

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

[0006] A downhole water injection distributor comprises a water pipe, wherein the bottom end of the water pipe is provided with two water outlet holes, a valve joint is fixedly installed on the outer side of the bottom end of the water pipe, a valve seat is arranged on the top of the valve joint, a filter ring is threadedly connected to the bottom end of the valve seat, and the bottom end of the filter ring is slidably connected to the top inner wall of the valve joint.

[0007] As a preferred embodiment of the utility model, the bottom end of the filter ring is threadedly connected with a bottom ring, and the outer side of the bottom ring is slidably connected to the top inner wall of the valve joint.

[0008] As a preferred embodiment of the utility model, a plurality of limit springs are fixedly mounted on the bottom end of the bottom ring, and the bottom ends of the plurality of limit springs are fixedly connected to the inner wall of the bottom end of the valve joint.

[0009] As a preferred embodiment of the utility model, a top ring is fixedly installed on the top end of the water pipe, a compression spring is fixedly installed on the bottom end of the top ring, and the bottom end of the compression spring is fixedly connected to the top end of the valve seat.

[0010] As a preferred embodiment of the utility model, the inner side wall of the valve seat is slidably connected to the outer side of the water pipe.

[0011] As a preferred embodiment of the present invention, a plurality of filter holes are provided on the outer side of the filter ring.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1) When the valve seat is subjected to water pressure, the filter ring can slide outward from the inside of the valve joint along with the valve seat, so that impurities in the water can be effectively filtered through the filter holes on the filter ring. At the same time, the filter ring can be effectively connected to the valve seat and the bottom ring at both ends, so that the filter ring is easier to disassemble when cleaning is required, thereby increasing the service life of the overall water distributor.

[0014] 2) The bottom ring set at the bottom end of the filter ring can effectively prevent the filter ring from detaching from the valve joint when sliding upward, thereby further effectively increasing the filter ring's filtering effect on impurities during the use of the water distributor.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4The utility model provides the following technical solutions: a downhole water injection distributor, comprising a water pipe 1, two water outlet holes 2 are provided at the bottom end of the water pipe 1, a valve joint 3 is fixedly installed on the outer side of the bottom end of the water pipe 1, a valve seat 4 is provided on the top of the valve joint 3, a filter ring 5 is threadedly connected to the bottom end of the valve seat 4, and the bottom end of the filter ring 5 is slidably connected to the top inner wall of the valve joint 3.

[0023] During specific use, when the water distributor is used, the water is output to the outside through the water outlet hole 2 on the water supply pipe 1. When the water pressure acts on the valve seat 4 to push it to slide upward, the filter ring 5 can be driven by the valve seat 4 to move upward synchronously, so that the filter ring 5 slides upward from the inside of the valve joint 3, and the impurities in the water output to the outside from the water outlet 2 can be effectively filtered and processed, and the top end of the filter ring 5 and the valve seat 4 can be separated from the valve seat 4 by rotating the filter ring 5, which can further increase the cleaning effect of the filter ring 5 after use, and then can effectively improve the service life of the water distributor.

[0024] Preferably, the bottom end of the filter ring 5 is threadedly connected to a bottom ring 6 , and the outer side of the bottom ring 6 is slidably connected to the top inner wall of the valve joint 3 .

[0025] During specific use, when the filter ring 5 is driven to move upward by the valve seat 4, the bottom ring 6 can be simultaneously driven to slide upward inside the valve joint 3, so that the filter ring 5 can be prevented from sliding upward and disengaging from the valve joint 3 by the bottom ring 6, and when the filter ring 5 rotates and disengages from the valve seat 4, the bottom end of the filter ring 5 rotates synchronously on the bottom ring 6, so that the filter ring 5 can be disassembled, which makes it easier to clean the filter ring 5.

[0026] Preferably, a plurality of limit springs 7 are fixedly mounted on the bottom end of the bottom ring 6 , and the bottom ends of the plurality of limit springs 7 are fixedly connected to the bottom inner wall of the valve joint 3 .

[0027] During specific use, the limit spring 7 at the bottom end of the bottom ring 6 can further increase the pressure required for the valve seat 4 to move upward, and can further increase the stability of the bottom ring 6 sliding inside the valve joint 3.

[0028] Preferably, a top ring 8 is fixedly installed on the top end of the water pipe 1 , a compression spring 9 is fixedly installed on the bottom end of the top ring 8 , and the bottom end of the compression spring 9 is fixedly connected to the top end of the valve seat 4 .

[0029] During specific use, when the valve seat 4 is subjected to water pressure, the compression spring 9 can exert a downward elastic force on the valve seat 4. When the force of the water pressure is greater than the elastic force of the compression spring 9 and the limit spring 7, the valve seat 4 moves upward to discharge the liquid inside the water pipe 1 from the water outlet 2.

[0030] Preferably, the inner side wall of the valve seat 4 is slidably connected to the outer side of the water pipe 1.

[0031] During specific use, when the valve seat 4 is subjected to the water pressure, it can slide upward on the outer side of the water pipe 1 as the water pressure gradually increases.

[0032] Preferably, a plurality of filter holes 51 are formed on the outer side of the filter ring 5 .

[0033] When in use, the filter ring 5 filters the liquid output from the water pipe 1 through the filter holes 51 thereon.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
