Technical Field

[0001] The utility model relates to the technical field of oil well equipment, in particular to an oil well flow regulating and water controlling device. Background Art

[0002] At present, water control and flow regulation screens are generally used in oil and gas wells that require early adjustment of the liquid production profile. During the production of oil and gas wells, due to the axial flow pressure difference or the difference in physical parameters such as permeability and porosity between layers, the liquid production of each layer varies greatly, with high permeability layers producing more liquid and low permeability layers producing less liquid. In the later stage, water is seen in the high permeability layer, the water content increases, and the high permeability layer forms a dominant channel, resulting in an increase in the water content of the overall oil well, and the production of the low permeability layer is suppressed and cannot be effectively mobilized.

[0003] The Chinese patent document with the authorization announcement number CN217735454U discloses a water control and flow regulating screen tube, including: a base tube, a retaining ring, a filter screen, a diversion device and an outer sleeve; the filter screen is set on the outside of the base tube, and the two ends of its outer wall are in contact with the limit baffle of the retaining ring. With respect to the above technical scheme, the following defects still exist: the existing technology blocks the sediment in the oil flow through the filter screen, but after a period of use, it is easy to cause blockage on the surface of the filter screen, thereby affecting the flow of oil. In addition, the filter screen is fixed on the outer sleeve, and when the filter screen is damaged, it is inconvenient to replace it.

[0004] Therefore, an oil well flow regulating and water controlling device is proposed. Utility Model Content

[0025] like Figures 1 to 4As shown, an oil well flow control water device includes a flow control water pipeline 1, one end of the flow control water pipeline 1 is fixedly connected to a connector 2, a mounting shell 3 is provided in the middle section of the flow control water pipeline 1, a filter assembly 4 for filtering sediment is installed on the surface of the mounting shell 3, a locking assembly 5 for limiting the filter assembly 4 is provided on the surface of the flow control water pipeline 1, and an anti-blocking assembly 6 for cleaning the filter assembly 4 is provided on the surface of the mounting shell 3. More specifically, the oil flow enters the interior of the flow control water pipeline 1 through the filter assembly 4, and the sediment in the oil flow is blocked outside by the filter assembly 4. Through the operation of the anti-blocking assembly 6, the surface of the filter assembly 4 can be cleaned to avoid sediment adhesion and blockage. When the filter assembly 4 is damaged, the filter assembly 4 can be released by the locking assembly 5 to remove and replace the filter assembly 4.

[0026] The filter assembly 4 includes a mounting groove 401, and the mounting groove 401 is opened on the surface of the mounting shell 3. The inner wall of the mounting groove 401 is movably connected with a filter screen 402. The surface of the filter screen 402 is fixedly connected with a connecting rod 403. The end of the connecting rod 403 is fixedly connected with an arc-shaped block 404, and the arc-shaped block 404 fits the surface of the flow control water pipeline 1. It should be noted that the filter screen 402 is inserted into the inner wall of the mounting groove 401. At this time, the arc-shaped block 404 is just stuck on the surface of the flow control water pipeline 1. The locking assembly 5 limits the arc-shaped block 404, and the installation of the filter screen 402 can be completed. The filter screen 402 can be used to filter the sediment in the oil flow. The filter screen 402 can be quickly disassembled by reverse operation.

[0027] The locking assembly 5 includes a fixing plate 501, and the fixing plate 501 is fixedly connected to the flow control water pipe 1, a plug post 502 is movably inserted on the surface of the fixing plate 501, a paddle 503 is fixedly connected to the top of the plug post 502, a spring 504 is fixedly connected between the paddle 503 and the fixing plate 501, a slot 505 is provided on the surface of the arc-shaped block 404, and the inner wall of the slot 505 is movably inserted with the end of the plug post 502. More specifically, by pulling the paddle 503, the plug post 502 is driven to move under the elastic force of the spring 504, so that the end of the plug post 502 is separated from the inner wall of the slot 505, the limit of the arc-shaped block 404 can be released, and the filter assembly 4 can be disassembled.

[0028] The anti-blocking assembly 6 includes a motor 601, and the motor 601 is fixedly installed inside the left side wall of the installation shell 3. The output end of the motor 601 is fixedly connected to a threaded column 602, and the surface of the threaded column 602 is threadedly connected to a bent rod 603, and the bent rod 603 is movably plugged with the installation shell 3. The end of the bent rod 603 is fixedly connected to a mounting plate 604, and the surface of the mounting plate 604 is fixedly connected to a cleaning brush 605. It should be noted that the motor 601 drives the threaded column 602 to rotate, and the bent rod 603 is driven to move under the action of the thread, which can drive the mounting plate 604 and the cleaning brush 605 to move, thereby cleaning the debris attached to the surface of the filter screen plate 402.

[0029] There are two groups of connecting rods 403 and arc-shaped blocks 404 on the surface of each filter screen plate 402, and the two groups of connecting rods 403 and arc-shaped blocks 404 are respectively located above and below the filter screen plate 402. More specifically, by symmetrically arranging the two groups of connecting rods 403 and arc-shaped blocks 404, the filter screen plate 402 is effectively limited at the upper and lower positions, making the installation of the filter screen plate 402 more stable.

[0030] Both ends of the arc-shaped clamping block 404 are fixedly connected with magnets 7. It should be noted that by installing magnets 7 at the ends of the arc-shaped clamping block 404, the magnets 7 close to each other are attracted to each other, thereby reinforcing the position limitation of the arc-shaped clamping block 404.

[0031] In summary: the oil flow enters the interior of the flow control water pipeline 1 through the filter component 4, and the mud and sand in the oil flow are blocked outside by the filter component 4. The surface of the filter component 4 can be cleaned by the operation of the anti-blocking component 6 to avoid mud and sand adhesion and blockage. When the filter component 4 is damaged, the limit of the filter component 4 can be released by the locking component 5, and the filter component 4 can be disassembled and replaced. During use, the effect of automatic cleaning of the filter structure is achieved, and blockage caused by mud and sand in the oil flow is avoided, thereby ensuring the flow of oil. When the filter structure is damaged, it is more convenient to replace.
