Description

Technical Field

[0001] The present invention relates to the technical field of oil well filling, in particular to intelligent filling equipment for petroleum and natural gas wells. Background Art

[0002] During the oil and gas extraction process, underground working conditions are complex and changeable, and continuous injection of chemical agents is required to maintain stable production. By precisely controlling the injection parameters of antifreeze, foaming agents, corrosion inhibitors and other agents, problems such as wellbore fluid accumulation, pipeline freezing and blockage, and equipment corrosion can be solved, thereby improving oil and gas recovery rates and production safety.

[0003] For example, the patent document with the prior art announcement number CN117145436B discloses a reagent filling device for oil and natural gas production, comprising a base plate, a reagent storage box, a heat exchanger, a liquid pumping and filling device, and a control cabinet. The reagent storage box is mounted on the upper surface of the base plate, the heat exchanger is interlaced with one side of the reagent storage box, the liquid pumping and filling device is mounted on the upper surface of the base plate, and the control cabinet is arranged on one side of the liquid pumping and filling device. The control cabinet is mounted on the upper surface of the base plate. The present invention utilizes a configuration in which the heat exchanger and the liquid pumping and filling device are coordinated to transmit an electrical signal to a spring-loaded safety valve via a pressure sensor, causing the spring-loaded safety valve to spring open. Then, the reagent inside the two-way liquid separation tank can flow in both directions, so that when the hydraulic pressure of the inductive liquid guide mechanism is too high, it can be self-depressurized. The pressure control effect is better when the reagent is added, which makes it easier to control the reaction between the reagent and the water or oil in the casing, thereby improving the production quality of oil and natural gas.

[0004] While existing technologies use pressure sensors to monitor pressure changes in the reagent in the gas well casing to indirectly determine its operating status, they face significant limitations in actual operation. For example, during long-term storage or transportation, foaming agents are prone to generating large numbers of stable bubbles due to disturbances. This can cause the agent to expand in volume and change in density, leading to fluctuations or distortion in pressure readings, making it difficult to accurately reflect the actual injection pressure and downhole operating conditions. More critically, foaming agents often contain volatile solvents (such as isopropyl alcohol). These components are prone to continuous dissipation in open or poorly sealed systems, resulting in an imbalance in the formulation's component ratios and a decrease in the concentration of the active ingredient. This not only weakens the agent's ability to regulate surface tension but also directly leads to a decrease in foaming power and foam stability, seriously impacting the sustainability and efficiency of the foaming operation. Therefore, relying solely on pressure sensing cannot effectively identify the degradation of the agent's physical and chemical properties, making it difficult to warn of the risk of formulation failure. This can lead to the illusion of "normal pressure but functional failure" during field use, seriously impacting the continuous and stable production of gas wells. To this end, this application proposes an intelligent filling device for oil and gas wells. Summary of the Invention

[0015] Preferably, a medicine injection port is provided on one side of the first medicine box, and a liquid level gauge is provided inside the first medicine box.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. A multi-way distributor is installed inside the tank to divert the chemical liquid. One side of the distributor is connected to a diversion pipe that is connected to the wellhead of each gas well. This structure enables the intelligent filling equipment to simultaneously fill multiple gas wells with chemicals. The multi-way distributor accurately diverts the chemical liquid to each gas wellhead, achieving the functions of centralized control and decentralized filling. This greatly improves filling efficiency, reduces manual operation and equipment investment, and lowers production costs. The intelligent dosing controller in the automation component integrates liquid level sensors, pressure sensors, temperature sensors, voltage sensors, and high-performance controllers and communication modules, which can monitor equipment operating parameters in real time. Through these sensors, the operating status of the equipment, such as the liquid level in the medicine tank, system pressure, temperature, etc., can be fully understood, abnormal conditions can be detected in a timely manner, and corresponding measures can be taken to ensure the normal operation of the equipment. At the same time, high-performance controllers and communication modules realize intelligent control and remote monitoring of the equipment. Staff can operate and monitor the equipment in the control room or through mobile terminals, which improves the convenience and efficiency of management. The high-pressure pump can deliver different reagents according to needs, without the need to set up independent delivery pumps and pipelines, which simplifies the equipment structure, reduces costs, and improves the flexibility and versatility of the equipment. The flow meter installed in the common pipe can accurately detect the amount of reagents added. Staff can accurately control the amount of reagents added according to the actual needs of the gas well, avoiding waste and over-injection of reagents, improving the efficiency of reagent use, reducing production costs, and also ensuring the safety and stability of gas well production.

[0017] 2. The floating cover is arranged inside the first medicine box and covers the surface of the medicine liquid. A plurality of floats are provided at its bottom. The floats can be attached to the surface of the medicine liquid and move with the liquid level, thereby changing the position of the floating cover and ensuring that the floating cover always closely adheres to the surface of the medicine liquid. This design can effectively reduce the contact area between the medicine liquid and the air, reduce the evaporation rate of the medicine liquid, and reduce the loss of medicine. The curved rubber skirt can further enhance the sealing between the floating cover and the inner wall of the first medicine box and reduce the volatilization of the medicine liquid. Moreover, when the floating cover rotates, the curved rubber skirt can alternately scrape away stains on the inner wall of the first medicine box, playing the role of cleaning the inner wall, keeping the interior of the medicine box clean, and facilitating the long-term storage and use of the medicine liquid. The multiple pentagonal skeletons arranged inside the curved rubber skirt have one end bent and connected to the curved rubber skirt, providing support for the curved rubber skirt. The pentagonal skeleton is a pentagonal bent structure that deforms when one end is squeezed by force, and one end is connected to the inner wall of the curved rubber skirt to restrict its deformation in the vertical direction. The sliding rod that slides inside the floating cover is connected to one end of the pentagonal skeleton through a connecting plate. When the sliding rod moves, it can change the shape of the pentagonal skeleton, thereby changing the arc angle of the curved rubber skirt, so that it better fits the inner wall of the first medicine box, improving the sealing and cleaning effect. The inert gas chamber is provided inside the first medicine box for storing inert gas. The sealing cover plate that is rotatably connected to the top of the floating cover is connected to the inert gas chamber through multiple air pipes for transporting inert gas into the floating cover. The introduction of inert gas can further reduce the volatilization of the foaming agent, because the inert gas has stable chemical properties and can form a protective film on the surface of the liquid medicine, reducing the contact and reaction between the liquid medicine and the air, thereby better preserving the medicine.

[0021] Example 1: Please refer to Figures 1-15The present invention provides a technical solution: an intelligent filling device for petroleum and natural gas wells, comprising a box body 100 and a first medicine box 102 and a second medicine box 103 placed therein.

By setting up the multi-way distributor 200, the medicine can be effectively diverted and transported to the wellheads of each gas well to discharge the medicine. By setting up the automation component, the high-pressure pump 203 and the multi-way distributor 200 can be effectively started to operate, thereby improving efficiency.

[0023] Among them, the automation component includes an intelligent dosing controller 204 for controlling the high-pressure pump 203 and the multi-way distributor 200, wherein the intelligent dosing controller 204 integrates a liquid level sensor, a pressure sensor, a temperature sensor, a voltage sensor and a high-performance controller and communication module for real-time monitoring of equipment operating parameters. A common pipe 206 is connected between the first medicine box 102 and the second medicine box 103, and one end of the common pipe 206 is connected to the input end of the high-pressure pump 203. A three-way valve 205 for switching the liquid medicine is installed in the common pipe 206, and the output end of the high-pressure pump 203 is connected to the delivery pipe 202 connected to the multi-way distributor 200. The three-way valve 205 can switch the input of the first medicine box 102 and the second medicine box 103, thereby facilitating the delivery of different medicines.

[0024] Furthermore, the top of the box 100 is rotatably connected to a rotating frame 208, one side of the rotating frame 208 is fixedly connected to a solar photovoltaic 207, the interior of the box 100 is fixedly connected to a drive motor 209 for driving the rotating frame 208 to rotate, and a light source tracking sensor is provided in the solar photovoltaic 207, which is controlled by the dosing intelligent controller 204, wherein a battery is provided in the box 100 to provide power, and the solar photovoltaic 207 can charge the battery, and the light source tracking sensor controls the operation of the drive motor 209 so that the solar photovoltaic 207 follows the sun for angle adjustment.

[0025] Specifically, when in use, the diversion pipe 201 is first connected to the wellhead of each gas well. The DC motor controller in the high-pressure pump 203 can be controlled by the intelligent dosing controller 204 to operate its DC motor, so that the medicine in the first medicine box 102 or the second medicine box 103 is transported to the high-pressure pump 203 through the common pipe 206, and then transported to the multi-way distributor 200 through the delivery pipe 202 for infusion, wherein the solar photovoltaic 207 can charge the battery and power the remaining electrical equipment.

[0026] In summary, the multi-way distributor 200 is arranged inside the box 100 for diverting the liquid medicine, and one side of the multi-way distributor is connected to a diversion pipe 201 connected to each gas wellhead. This structure enables the intelligent filling equipment to fill multiple gas wells with medicine at the same time, and accurately diverts the liquid medicine to each gas wellhead through the multi-way distributor 200, realizing the functions of centralized control and decentralized filling, greatly improving the filling efficiency, reducing manual operation and equipment investment, and reducing production costs. The intelligent dosing controller 204 in the automation component integrates liquid level sensors, pressure sensors, temperature sensors, voltage sensors, and high-performance controllers and communication modules, which can monitor the equipment operating parameters in real time.

At the same time, the high-performance controller and communication module realize the intelligent control and remote monitoring of the equipment. The staff can operate and monitor the equipment in the control room or through the mobile terminal, which improves the convenience and efficiency of management.

The staff can accurately control the amount of agent added according to the actual needs of the gas well, avoiding waste and over-filling of agents, improving the use efficiency of agents, reducing production costs, and also ensuring the safety and stability of gas well production.

[0027] Example 2: Please refer to Figures 1-15The present invention also provides a technical solution, which is different from the technical solution of the first embodiment: an intelligent filling equipment for petroleum and natural gas wells, further comprising a floating cover 300, which is arranged inside the first medicine box 102 and covers the surface of the medicine liquid, and a plurality of floats 306 are provided at the bottom thereof, and the outer surface of the floating cover 300 is provided with a plurality of arc-shaped rubber skirts 305 that fit with the inner wall of the first medicine box 102, and a defoaming component for eliminating bubbles in the medicine liquid is provided inside the floating cover 300. By providing the defoaming component, bubbles generated by the medicine liquid can be reduced. At the same time, the floating cover 300 covers the surface of the medicine liquid to reduce the contact area between it and the air, thereby reducing evaporation and providing protection, and the floats 306 can be attached to the surface of the medicine liquid, and move with the liquid level of the medicine liquid to change the position of the floating cover 300.

[0028] It also includes an inert gas chamber 400, which is arranged inside the first medicine box 102 and is used to store inert gas, and a sealing plate 401 rotatably connected to the top of the floating cover 300, which is connected to the inert gas chamber 400 through multiple air pipes 402 and is used to transport the inert gas into the floating cover 300, and an air sealing hole 307 for the inert gas to pass through is opened inside the float 306, and a plug 405 for sealing itself is rotatably connected inside the air pipe 402, and a throttling component for controlling the opening and closing of the plug 405 is provided in the sealing plate 401, wherein the introduction of the inert gas can further reduce the volatilization of the foaming agent, and the throttling component can control the release amount of the inert gas, thereby reducing the excessive introduction of inert gas into the floating cover 300.

[0029] Furthermore, the defoaming component includes a plurality of internal spikes 308 fixedly connected to the inside of the floating cover 300, a reduction motor 302 is fixedly connected to the top of the first medicine box 102, the output end of the reduction motor 302 extends to the inside of the first medicine box 102 and is fixedly connected to a rotating rod 301 spline-connected to the floating cover 300, a plurality of pentagonal skeletons 312 are arranged inside the arc-shaped rubber strip skirt 305, and one end of the pentagonal skeleton 312 is bent and connected to the arc-shaped rubber strip skirt 305, a sliding rod 309 is slidably connected inside the floating cover 300, one end of the sliding rod 309 is fixedly connected to a connecting plate 314 connected to one end of the pentagonal skeleton 312, a purge port 316 is provided on one side of the arc-shaped rubber strip skirt 305, an air release groove 311 is provided inside the sliding rod 309, and an inflation cavity 315 is provided inside the floating cover 300. The rotation of the floating cover 300 can stir the liquid and cause the bubbles to move due to centrifugal force. Under the push of the float 306, the bubbles are punctured by the inner thorn 308. At the same time, the stirring can also eliminate the bubbles. The pentagonal skeleton 312 is located inside the arc-shaped rubber skirt 305 to provide support for it. The pentagonal skeleton 312 is a pentagonal bending structure. When one end of the pentagonal skeleton is squeezed, it will deform. One end of the pentagonal skeleton 312 is connected to the inner wall of the arc-shaped rubber skirt 305 to limit it, so that it deforms in the vertical direction. With the cooperation of the sliding rod 309, automatic extrusion is achieved. The purge port 316 can be used for the discharge of part of the inert gas to purge the interior of the first medicine box 102. At the same time, the arc-shaped rubber skirt 305 scrapes off the stains on the inner wall of the first medicine box 102 in an interlaced manner when the floating cover 300 rotates.

[0030] Furthermore, the throttling assembly includes a lifting rod 408 slidably connected to the inside of the cover plate 401, the bottom of the lifting rod 408 is fixedly connected to the first magnetic plate 410, and the interior of the floating cover plate 300 is provided with a second magnetic plate 413 that is attracted to the first magnetic plate 410. The top of the lifting rod 408 is fixedly connected to the transmission rod 407, one end of the transmission rod 407 extends into the air pipe 402 and is slidably connected and rotatably connected to the pull rod 406, and one end of the pull rod 406 is rotatably connected to the plug 405, the bottom of the second magnetic plate 413 is fixedly connected to the connecting rod 411, and the bottom of the connecting rod 411 is rotatably connected to the ball 414, the interior of the sliding rod 309 is provided with a slope 313, and the ball 414 is slidably connected to the top of the slope 313, and the sliding rod 309 is provided with a slope 313. The outer surface of 09 is provided with a first spring 310 for its own reset. By setting the floating cover plate 300 to rotate and the sealing cover plate 401 to be stationary, the staggered magnetic attraction between the multiple first magnetic attraction plates 410 and the multiple second magnetic attraction plates 413 can be achieved, so that the lifting rod 408 and the connecting rod 411 move up and down, and the movement of the lifting rod 408 will intermittently open and close the transmission plug 405, and the movement of the connecting rod 411 will change the movement of the sliding rod 309. As the sliding rod 309 moves, the flow direction of the inert gas can be changed. When the sliding rod 309 moves, the air discharge groove 311 will be used to discharge the inert gas. The inert gas can pass through the air discharge groove 311 and pass through the inflation cavity 315 again to enter the interior of the arc-shaped rubber strip skirt 305, and finally be discharged through the purge port 316.

[0031] Among them, the internal structure of the air pipe 402 is equipped with a telescopic tube 403, the outer surface of the connecting rod 411 is provided with a third spring 412 for its own reset, the outer surface of the lifting rod 408 is provided with a second spring 409 for its own reset, and the bottom of the rotating rod 301 is fixedly connected with a plurality of tilt rods 303, and the outer surfaces of the plurality of tilt rods 303 are evenly fixedly connected with a plurality of stirring blades 304. By setting the telescopic tube 403, the air pipe 402 can be extended, so that the sealing plate 401 can move with the floating cover plate 300, and at the same time, the plurality of stirring blades 304 can effectively stir the foam discharge agent.

[0032] Specifically, the reduction motor 302 is turned on to drive the rotating rod 301 to rotate, so that the tilt rod 303 drives the stirring blade 304 to disturb the foam removal agent, and the rotating rod 301 will drive the floating cover plate 300 to rotate with it. As the floating cover plate 300 rotates, the multiple floating balls 306 at the bottom thereof will slide on the surface of the foam removal agent, thereby pushing the foam to move away from the axis of the floating cover plate 300, and then colliding with the multiple internal thorns 308 and being punctured and eliminated. The sealing plate 401 is connected to the inert gas cavity 400 through the multiple air pipes 402 and is in a stationary state. As the floating cover plate 300 continues to rotate, the second magnetic plate 413 and the first magnetic plate 410 staggered magnetic reaction occurs, and when the first magnetic plate 410 and the second magnetic plate 413 are attracted to each other, the connecting rod 411 is driven to move, pulling the ball 414 upward. At this time, the sliding rod 309 moves under the reset force of the first spring 310, thereby causing the air release groove 311 to be misaligned, so that the gas in the floating cover plate 300 will escape through the air release groove 311. The escaping gas will enter the interior of the curved rubber strip skirt 305 through the inflation cavity 315, and then be discharged through the purge port 316 to be blown to the inner wall of the first medicine box 102. Then, at the same time, the sliding rod 309 will push the pentagonal frame 312 to bend through the connecting plate 314. The arc angle of the curved rubber strip skirt 305 is thereby increased so that it can better fit the inner wall of the first medicine box 102. At the same time, during this process, the first magnetic plate 410 will also drive the lifting rod 408 to move downward, thereby driving the transmission rod 407 to move, thereby driving the pull rod 406 to open the plug 405 to allow the inert gas in the inert gas chamber 400 to be transported to the inside of the sealing plate 401 through the air pipe 402, and then discharged to the inside of the floating cover plate 300 through the multiple air injection holes 404, and then covered with the inside of the air sealing hole 307 to air-seal the foaming agent. As the floating cover plate 300 continues to move, the first magnetic plate 410 and the second magnetic plate 413 will be separated. The magnetic attraction range is reached, and then the two are quickly reset. During this process, the lifting rod 408 moves upward to push the pull rod 406 to reset, so that the plug 405 blocks the air pipe 402 again, so that the inert gas in the inert gas chamber 400 stops being discharged. In the process of moving down and resetting, the connecting rod 411 drives the ball 414 to roll on the inclined surface of the slope 313, so that the sliding rod 309 moves and changes the position of the air release groove 311, thereby blocking the gas in the floating cover 300 from escaping. At the same time, the pentagonal frame 312 is pulled by the connecting plate 314 to extend, thereby reducing the contact area with the inner wall of the first medicine box 102, thereby improving its efficiency in hanging and removing stains.

[0033] In summary, the floating cover 300 is positioned within the first medicine box 102 and covers the surface of the liquid medicine. Multiple floats 306 are located at its base. The floats 306 adhere to the liquid medicine surface and follow its movement, thereby adjusting the position of the floating cover 300 and ensuring it remains firmly in contact with the liquid medicine surface. This design effectively reduces the contact area between the liquid medicine and air, slowing its evaporation rate and minimizing drug loss. The curved rubber skirt 305 further enhances the seal between the floating cover 300 and the inner wall of the first medicine box 102, reducing drug volatilization. Furthermore, when the floating cover 300 rotates, the curved rubber skirt 305 can alternately scrape away dirt from the inner wall of the first medicine box 102, cleaning the inner wall and maintaining the cleanliness of the medicine box, which is conducive to the long-term storage and use of the liquid medicine. Multiple pentagonal skeletons 312 are disposed within the curved rubber skirt 305, with one end bent and connected to the curved rubber skirt 305, providing support for the curved rubber skirt 305. The pentagonal skeletons 312 are pentagonal and bent. When one end is squeezed, they deform. The connection at one end to the inner wall of the curved rubber skirt 305 restricts their deformation in the vertical direction. A sliding rod 309, which slides inside the floating cover 300, is connected at one end to one end of the pentagonal frame 312 via a connecting plate 314. Movement of the sliding rod 309 alters the shape of the pentagonal frame 312, thereby changing the angle of the curved rubber skirt 305, allowing it to better conform to the inner wall of the first medicine box 102 and improve sealing and cleaning effectiveness. An inert gas chamber 400 is located within the first medicine box 102 and is used to store inert gas. A sealing plate 401, pivotally connected to the top of the floating cover 300, communicates with the inert gas chamber 400 via multiple air pipes 402, which are used to deliver inert gas into the floating cover 300. The introduction of inert gas further reduces the volatilization of the foaming agent because the inert gas is chemically stable and can form a protective film on the surface of the liquid medicine, reducing contact and reaction between the liquid medicine and air, thereby better preserving the medicine.

[0034] Working principle: When in use, first connect the diversion pipe 201 to the wellhead of each gas well. The intelligent dosing controller 204 can control the operation of the DC motor controller in the high-pressure pump 203 to make its DC motor run, so that the liquid medicine in the first medicine box 102 or the second medicine box 103 is transported to the high-pressure pump 203 through the common pipe 206, and then transported to the multiplexer 200 through the delivery pipe 202 for infusion. The solar photovoltaic 207 can charge the battery and power other electrical equipment. The first medicine box 102 is used to store the foaming agent. The reduction motor 302 can be continuously turned on to drive the rotating rod 301 to rotate, so that the tilting rod 303 drives the stirring blade 304 to disturb the foaming agent. At the same time, the rotating rod 301 will drive the floating cover 300 to rotate with it. As the floating cover 300 rotates, the multiple floating balls 306 at its bottom will slide on the surface of the foaming agent, thereby pushing the foam to move away from the axial position of the floating cover 300, and then it will conflict with the multiple internal thorns 308 and be punctured and eliminated. The sealing plate 401 is connected to the inert gas chamber 400 through multiple air pipes 402 and is in a static state. As the floating cover 300 continues to rotate, the second magnetic plate 413 and the first magnetic plate 410 will intertwine and produce a magnetic attraction reaction. When the first magnetic plate 410 and the second magnetic plate 413 are attracted to each other, the connecting rod 411 will be driven to move and pull the ball 414 upward. At this time, the sliding rod 309 is under the influence of the first spring 310 The gas in the floating cover 300 will escape through the gas relief groove 311, and the escaped gas will enter the interior of the arc-shaped rubber strip skirt 305 through the air-blowing cavity 315, and then be discharged through the purge port 316 to the inner wall of the first medicine box 102. At the same time, the sliding rod 309 will push the pentagonal frame 312 to bend through the connecting plate 314, thereby increasing the arc angle of the arc-shaped rubber strip skirt 305 so that it can better fit the inner wall of the first medicine box 102. At the same time, in this process, the first magnetic plate 410 will also drive the lifting rod 408 to move downward, thereby driving the transmission rod 407 to move, thereby driving the pull rod 406 to open the plug 405 to allow the inert gas in the inert gas cavity 400 to be transported to the interior of the sealing plate 401 through the air pipe 402, and then be discharged to the interior of the floating cover 300 through the multiple air injection holes 404, and then cover the inside of the air sealing hole 307 to seal the foaming agent. As the floating cover 300 continues to move, the first magnetic plate 410 and the second magnetic plate 413 will leave the magnetic attraction range, and then the two will quickly reset. During this process, the lifting rod 408 moves upward to push the pull rod 406 to reset, so that the plug 405 re-blocks the air pipe 402, so that the inert gas in the inert gas chamber 400 stops being discharged. In the process of moving downward and resetting, the connecting rod 411 will drive the ball 414 to roll on the inclined surface of the slope 313, so that the sliding rod 309 moves and changes the position of the air release groove 311, thereby blocking the gas in the floating cover 300 from escaping. At the same time, the pentagonal frame 312 is pulled by the connecting plate 314 to extend, thereby reducing the contact area with the inner wall of the first medicine box 102, thereby improving its efficiency in removing stains.
