This water distributor for oil extraction is reasonably designed, safe and reliable, and can meet the use requirements in harsh environments such as offshore oil fields. A water distributor for oil extraction includes: an outer pipe (1), an inner pipe (2); among them, the inner pipe (2) is arranged inside the outer pipe, and a connection hole (21) is arranged on the inner pipe, and a water spraying hole (11) is arranged on the outer pipe; on the outer wall of the inner pipe, a first partition plate (22) and a second partition plate (23) are respectively arranged in the same direction as the axis of the inner pipe, and a water distribution component is also arranged in the chamber space between the first partition plate (22) and the second partition plate (23). The water distribution component includes a flow-through pipeline (51), a first control component (8), and a second control component (9). Based on the above content, the applicant believes that the following defects exist: This water distributor for oil extraction includes an outer pipe and an inner pipe, is reasonably designed, safe and reliable, and can meet the use requirements in harsh environments such as offshore oil fields. However, this device cannot effectively adjust the water injection flow rate of water injection, and there will be situations where the water injection volume is too large or too small during long-term water injection, and these situations will affect the overall water injection work.

[0004] Therefore, it is very necessary to design a water distributor for oil extraction with strong practicability and controllable water injection volume. Summary of the Invention

[0005] The purpose of the present invention is to provide a water distributor for oil extraction to solve the problems raised in the above background art.

[0006] To solve the above technical problems, the present invention provides the following technical solution: A water distributor for oil extraction includes a main body of the water distributor, an upper connecting pipe is installed at the top of the main body of the water distributor, a lower connecting pipe is installed at the bottom of the main body of the water distributor, a water inlet treatment mechanism is arranged at the top of the main body of the water distributor, and a water distribution mechanism is arranged inside the main body of the water distributor; The water distribution mechanism includes a first connecting circular plate, which is installed at the inner top of the upper connecting pipe. At both the left and right ends inside the main body of the water distributor, there are fixedly connected fixing frames. Inside the fixing frames, there are fixedly connected fixing columns. A slider is slidably connected to the surface of the fixing column. A spring is sleeved on the surface of the fixing column. The inner end of the slider is fixedly connected to a water distribution chamber. An internal water distribution port is opened on the front of the water distribution chamber.

After the water enters the water distribution chamber, it presses the water distribution chamber to descend. The slider slides on the fixing column, moving the internal water distribution port to an appropriate water distribution port for water distribution work. When the pre-calculated water distribution work is completed, the drainage pump is turned on for rapid drainage work. At this time, due to the reduction of gravity, the water distribution chamber is reset by the spring, moving the water distribution chamber to one end of the main body of the water distributor away from the water distribution port, thus stopping the water distribution work. The setting of this mechanism can achieve controllable water distribution work, accurately adjust the water injection volume according to the requirements of the oil layer, and the adjustment range meets the requirements of different mining stages. During the water inlet process, the setting of the sealed connecting port can ensure the sealing of the pipeline, prevent water injection leakage, and ensure stable water injection pressure.

It is made of corrosion-resistant metal, can always maintain good sealing performance during the movement of components, effectively prevent fluid leakage, and at the same time adapt to a certain degree of axial and radial displacement, improving the reliability of the seal.

[0007] According to the above technical solution, the water distribution chamber is arranged inside the fixing frame. There are two groups of fixing frames. There are two groups of fixing columns and sliders. The water distribution chamber slides on the surface of the fixing column through the slider.

[0008] According to the above technical solution, springs are fixedly connected to both the top and bottom of the slider. Both the telescopic water inlet pipe and the telescopic water outlet pipe are made of telescopic hose material.

[0009] According to the above technical solution, the water inlet treatment mechanism includes an extended inlet pipe. An inlet port is installed at the top of the extended connecting pipe. The extended inlet pipe is installed at the top of the inlet port. A fixing frame is provided at the inner top of the extended inlet pipe. A detachable filter screen is installed inside the fixing frame. An installation plate is fixedly connected to the inner top of the fixing frame. An equalizing and distributing paddle is installed at the inner end of the installation plate. Hooks are fixedly connected to the left and right ends at the top of the fixing frame. A collar is fixedly connected to the bottom of the outer end of the hook. A jack is provided at the top of the extended inlet pipe. A socket is provided at the top of the extended inlet pipe. A plug column is fixedly connected to the bottom end of the socket. Auxiliary clamping interfaces are provided on the left and right sides at the bottom of the socket. A water injection port is fixedly connected to the top of the socket.

[0010] According to the above technical solution, the collar is fixedly connected to the bottom of the end of the hook away from the fixing frame, and the fixing frame is hung on the inner top of the extended inlet pipe through the hook and the collar.

[0011] According to the above technical solution, the plug column is inserted into the jack, and the socket is inserted into the top of the extended inlet pipe through the plug column.

[0012] According to the above technical solution, the auxiliary clamping interfaces correspond to the hooks one by one, and the collar is sleeved on the outer top of the extended inlet pipe.

[0013] According to the above technical solution, a water distribution port is fixedly connected to the right end of the main body of the water distributor. There are three groups of water distribution ports. An outlet port is installed at the bottom end of the lower connecting pipe.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: 1. In the present invention, through the setting of the water distribution mechanism, water will enter the main body of the water distributor through the device, enter the water distribution chamber through the telescopic inlet pipe, and inject an appropriate amount of water according to the required depth of water distribution. After the water enters the water distribution chamber, it presses the water distribution chamber to descend. The built-in water distribution port is moved to the appropriate water distribution port for water distribution work by sliding the slider on the fixed column. When the pre-calculated water distribution work is completed, the drainage pump is turned on for rapid drainage work. At this time, due to the reduction of gravity, the water distribution chamber is reset by the spring, and the water distribution chamber is moved to the end of the main body of the water distributor away from the water distribution port, thus stopping the water distribution work. The setting of this mechanism can achieve controllable water distribution work, can accurately adjust the water injection volume according to the oil layer demand, and the adjustment range meets the requirements of different mining stages.

[0015] 2. In the present invention, by providing a sealed connection port, a telescopic water inlet pipe, and a telescopic water outlet pipe, in the water inlet link of the water distributor for oil extraction, the design of each component is exquisite, effectively ensuring the stability and efficiency of the water injection work. The setting of the sealed connection port is crucial. It is like a solid defense line, greatly ensuring the pipeline sealing performance. During the water injection process, it can effectively prevent water injection leakage, enabling the water injection pressure to always remain stable, laying a good foundation for the subsequent water distribution operation. The design of the telescopic water inlet pipe and the telescopic water outlet pipe is also ingenious. They can flexibly expand and contract as the water distribution chamber moves, without affecting the normal operation of the water distribution chamber at all. Moreover, these two pipes are made of corrosion-resistant metal, which has obvious material advantages. During the movement of the components, it can always maintain good sealing performance, effectively preventing fluid leakage. At the same time, it can also adapt to a certain degree of axial and radial displacement, further improving the reliability of the seal and ensuring the safety of the entire water distribution process.

[0016] 3. In the present invention, by providing a water inlet treatment mechanism, when water enters the device from the water injection port, the water will first enter through the water equalizing and distributing paddle blades. Due to the impact of the water flow, the water equalizing and distributing paddle blades will be driven to rotate. Since the surface of the water equalizing and distributing paddle blades is arc-shaped, it can guide the water flow, making the water flow entering below appear to achieve uniform downward flow, thereby improving the uniformity and stability of downhole water injection to a certain extent. The water flow passes through a detachable filter screen to intercept impurities in the water flow, preventing impurities from blocking the components inside the main body of the water distributor. This mechanism can effectively intercept larger particles of impurities, such as rock debris, rust, etc., and has relatively little resistance to the water flow, not overly affecting the water injection flow rate.

[0017] 4. In the present invention, by providing a hook and a socket, in the structural design of the water distributor for oil extraction, the installation method of the fixed frame is ingenious, greatly improving the maintainability of the equipment. The fixed frame is cleverly installed at the bottom inside the extended water inlet pipe by means of the hook and the collar. This design enables the overall disassembly of the fixed frame to be completed quickly. When the equipment needs to be repaired or maintained, the operator can quickly separate the fixed frame from the extended water inlet pipe, saving a lot of time and effort. At the same time, to ensure the stability of the fixed frame during operation, a socket is specially provided. The socket can perform secondary limiting on the hook through the auxiliary clamping interface, effectively preventing the fixed frame from falling off due to factors such as water flow impact during long-term water injection work. Moreover, not only the fixed frame, but also components such as the hook, collar, and socket can be quickly disassembled. The characteristic that each component can be quickly disassembled makes the entire water distributor easy to disassemble and maintain, better adapting to the needs of long-term water injection work and ensuring the continuous and stable progress of the water distribution operation for oil extraction.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] The present invention provides the following technical solutions: Embodiment 1

[0022] Please refer to Figures 1-6 , the present invention provides a technical solution: A water distributor for oil extraction includes a main body 1 of the water distributor. An upper connecting pipe 2 is installed at the top of the main body 1 of the water distributor, a lower connecting pipe 5 is installed at the bottom of the main body 1 of the water distributor, a water inlet treatment mechanism 7 is arranged at the top of the main body 1 of the water distributor, and a water distribution mechanism 8 is arranged inside the main body 1 of the water distributor; The water distribution mechanism 8 includes a first connecting circular plate 81 which is installed at the inner top of the upper connecting pipe 2. At the left and right ends inside the main body 1 of the water distributor, there are fixedly connected fixing frames 82. Inside the fixing frames 82, there are fixedly connected fixing columns 83. On the surface of the fixing columns 83, there is a sliding connection with sliders 84. A spring 85 is sleeved on the surface of the fixing columns 83. The inner end of the slider 84 is fixedly connected with a water distribution chamber 86. On the front of the water distribution chamber 86, there is an internally placed water inlet 87. At the center of the top of the water distribution chamber 86, there is a fixedly connected sealed connecting pipe port 88. Between the first connecting circular plate 81 and the sealed connecting pipe port 88, there is an installed telescopic water inlet pipe 89. At the bottom of the water distribution chamber 86, there is a drainage pump 801. At the inner bottom of the lower connecting pipe 5, there is a second connecting circular plate 802. Between the drainage pump 801 and the second connecting circular plate 802, there is an installed telescopic water outlet pipe 803. Water will enter the main body 1 of the water distributor through the device, enter the interior of the water distribution chamber 86 through the telescopic water inlet pipe 89, and inject an appropriate amount of water according to the required depth of water distribution. After the water enters the water distribution chamber 86, it presses the water distribution chamber 86 to descend. By sliding the slider 84 on the fixing column 83, the internally placed water inlet 87 is moved to an appropriate water inlet 4 for water distribution work. When the pre-calculated water distribution work is completed, the drainage pump 801 is turned on for rapid drainage work. At this time, due to the reduction of gravity of the water distribution chamber 86, it is reset through the spring 85, and the water distribution chamber 86 is moved to one end of the main body 1 of the water distributor away from the water inlet 4, thus stopping the water distribution work. The setting of this mechanism can achieve controllable water distribution work, can accurately adjust the water injection volume according to the oil layer requirements, and the adjustment range meets the requirements of different mining stages. During the water inlet process, the setting of the sealed connecting pipe port 88 can ensure the pipeline sealing, prevent water injection leakage, and ensure the stability of the water injection pressure. The settings of the telescopic water inlet pipe 89 and the telescopic water outlet pipe 803 can move along with the water distribution chamber 86 and will not affect the work of the water distribution chamber 86. It is made of corrosion-resistant metal, can always maintain good sealing performance during the movement of components, effectively prevent fluid leakage, and at the same time adapt to a certain degree of axial and radial displacement to improve the reliability of the seal; The water distribution chamber 86 is arranged inside the fixing frame 82. There are two groups of fixing frames 82, two groups of fixing columns 83 and sliders 84. The water distribution chamber 86 slides on the surface of the fixing column 83 through the slider 84; Springs 85 are fixedly connected to both the top and bottom of the slider 84. Both the telescopic water inlet pipe 89 and the telescopic water outlet pipe 803 are made of telescopic hose material. Embodiment 2

[0023] Please refer to Figures 1-6, and on the basis of the first embodiment, it is further obtained that the water inlet treatment mechanism 7 includes an extended water inlet pipe 71. An inlet port 3 is installed at the top of the upper connecting pipe 2, and the extended water inlet pipe 71 is installed at the top of the inlet port 3. A fixing frame 72 is arranged at the top inside the extended water inlet pipe 71. A detachable filter screen 73 is installed inside the fixing frame 72. An installation plate 76 is fixedly connected to the inner top of the fixing frame 72. An even water distribution paddle 77 is installed at the inner end of the installation plate 76. Hooks 74 are fixedly connected to the left and right ends at the top of the fixing frame 72. A collar 75 is fixedly connected to the bottom of the outer end of the hook 74. A jack 78 is opened at the top of the extended water inlet pipe 71. A socket 79 is arranged at the top of the extended water inlet pipe 71. A plug column 701 is fixedly connected to the bottom end of the socket 79. Auxiliary clamping interfaces 702 are opened on both sides at the bottom of the socket 79. A water injection port 703 is fixedly connected to the top of the socket 79. When water enters the device through the water injection port 703, the water will first enter through the even water distribution paddle 77. Due to the impact of the water flow, the even water distribution paddle 77 will be driven to rotate. Since the surface of the even water distribution paddle 77 is arc-shaped, it can guide the water flow, so that the water flow entering below seems to achieve uniform water discharge, and thus the uniformity and stability of underground water injection can be improved to a certain extent. The water flow is filtered through the detachable filter screen 73, and the impurities in the water flow are intercepted, which can prevent the impurities from blocking the components inside the main body 1 of the water distributor. This mechanism can effectively intercept larger particles of impurities, such as rock debris, rust, etc., and has relatively little resistance to the water flow, and will not overly affect the water injection flow rate; The collar 75 is fixedly connected to the bottom of the end of the hook 74 away from the fixing frame 72, and the fixing frame 72 is hung on the inner top of the extended water inlet pipe 71 through the hook 74 and the collar 75; The plug column 701 is inserted into the jack 78, and the socket 79 is inserted into the top of the extended water inlet pipe 71 through the plug column 701; The auxiliary clamping interface 702 corresponds to the hook 74 one by one, and the collar 75 is sleeved on the outer top of the extended water inlet pipe 71; A water distribution port 4 is fixedly connected to the right end of the main body 1 of the water distributor. There are three groups of water distribution ports 4, and an outlet port 6 is installed at the bottom end of the lower connecting pipe 5.

[0024] In the actual operation process, when this device is used, when water enters the device through the water injection port 703, the water will first enter through the even water distribution paddle 77. Due to the impact of the water flow, the even water distribution paddle 77 will be driven to rotate. Since the surface of the even water distribution paddle 77 is arc-shaped, it can guide the water flow, so that the water flow entering below seems to achieve uniform water discharge, and thus the uniformity and stability of underground water injection can be improved to a certain extent. The water flow is filtered through the detachable filter screen 73, and the impurities in the water flow are intercepted, which can prevent the impurities from blocking the components inside the main body 1 of the water distributor. This mechanism can effectively intercept larger particles of impurities, such as rock debris, rust, etc., and has relatively little resistance to the water flow, and will not overly affect the water injection flow rate; The fixing bracket 72 is installed at the inner bottom of the extended water inlet pipe 71 through the hook 74 and the collar 75, and the whole can be quickly disassembled. At the same time, the socket 79 can perform secondary limit on the hook 74 through the auxiliary card interface 702 to prevent the fixing bracket 72 from falling off during work. These components can all achieve quick disassembly, and the whole is easy to disassemble for maintenance, which can be applicable to long-term water injection work; Water will enter the main body 1 of the water distributor through the device, enter the inside of the water distribution chamber 86 through the telescopic water inlet pipe 89, and inject an appropriate amount of water according to the required water distribution depth. After the water enters the water distribution chamber 86, it presses the water distribution chamber 86 to descend, slides on the fixed column 83 through the slider 84, and moves the built-in water distribution port 87 to the appropriate water distribution port 4 for water distribution work. When the pre-calculated water distribution work is completed, the drainage pump 801 is turned on for rapid drainage work. At this time, due to the reduction of gravity, the water distribution chamber 86 is reset by the spring 85, and the water distribution chamber 86 is moved to one end of the main body 1 of the water distributor away from the water distribution port 4, thus stopping the water distribution work. The setting of this mechanism can achieve controllable water distribution work, can accurately adjust the water injection volume according to the oil layer demand, and the adjustment range meets the requirements of different mining stages; During the water inlet process, the setting of the sealed pipe connection port 88 can ensure the sealing of the pipeline, prevent water injection leakage, and ensure the stability of the water injection pressure. The settings of the telescopic water inlet pipe 89 and the telescopic water outlet pipe 803 can move along with the water distribution chamber 86 without affecting the work of the water distribution chamber 86. The telescopic water inlet pipe 89 and the telescopic water outlet pipe 803 are made of corrosion-resistant metal. This material selection has great advantages. During the movement of the components of the water distributor, the corrosion-resistant metal always maintains excellent sealing performance with its good physical and chemical properties, just like adding a strong protective film to the pipeline, which can effectively block fluid leakage. Moreover, it also has the ability to adapt to a certain degree of axial and radial displacement. Even under complex working conditions, it can respond flexibly, further strengthening the reliability of the seal and ensuring the stable progress of the water distribution operation.
