Description
Technical Field
[0001] This invention relates to the field of natural gas extraction technology, specifically to a high-efficiency, energy-saving equipment for natural gas extraction. Background Technology
[0002] With the continuous growth of global energy demand, natural gas, as a clean energy source, is playing an increasingly important role in energy consumption. The innovation and development of natural gas extraction technology is rooted in the urgent need for the optimization and transformation of the global energy structure and environmental protection. As the proportion of natural gas as a clean energy source in global energy consumption increases year by year, efficient and environmentally friendly extraction technology has become the key to promoting the development of the natural gas industry.
[0003] In the field of natural gas extraction, traditional extraction equipment still has some shortcomings. During the natural gas extraction process, due to suitable temperature and pressure conditions inside the wellbore, water vapor in the natural gas easily combines with gas molecules to form water clumps. These water clumps accumulate rapidly inside the gas extraction and liquid extraction pipelines, severely clogging the pipelines and causing a significant reduction in the flowability of natural gas and liquids. As a result, extraction efficiency is severely affected. Once water clumps are formed, it is necessary to increase the energy output of the equipment in order to ensure normal extraction efficiency, which leads to increased energy consumption during the extraction process. In the subsequent processing, a lot of time and resources are often required for cleanup, which not only increases the extraction cost but may also cause safety accidents. Summary of the Invention

The buoyancy plate is a hollow structure and has strong buoyancy.
[0011] Furthermore, a water valve seat is provided in the middle section of the liquid extraction pipeline. Both ends of the water valve seat are provided with pipe connection ports that connect to the liquid extraction pipeline. A valve core is provided inside the pipe connection port. A rotatable force-receiving gear is provided on the upper surface of the valve core. A protective sealing box is also provided on the upper surface of the water valve seat.

[0012] Furthermore, the isolation assembly includes: an adjustment box, one side surface of which is fixedly connected to one side surface of the separator sleeve, and the other end of the adjustment box is provided with a gas transmission pipe and a liquid transmission pipe, both of which are provided with pipe joints at their ends, and the two pipe joints are respectively connected to one end of a liquid extraction pipe and a natural gas pipe.
[0013] Furthermore, a fixed partition and a movable partition are provided at the center of the adjustment box.

[0016] Compared with the prior art, the beneficial effects of the present invention are:
[0017] 1. In this solution, an anti-caking mechanism is installed. By adjusting the heater in the component, the gas and liquid entering the extraction head pipe are heated, which increases the internal temperature of the pipeline. This reduces the possibility of water vapor condensing into water condensate due to low temperature. At the same time, the fan blades are used to disperse the small-scale water condensate that has already formed, preventing it from accumulating and blocking the pipeline. The airflow is also used to evenly cover the inside of the pipeline with heat, further enhancing the anti-caking effect. The liquid removal component separates the gas and liquid through the partition plate in the partition sleeve, avoiding the mixing of gas and liquid in the pipeline, reducing the moisture carried in the natural gas, reducing the formation of water condensate inside the natural gas pipeline, reducing the risk of abnormal pressure rise and safety accidents caused by water condensate blockage, and reducing the energy consumption of gas extraction and liquid extraction, thus improving the transmission efficiency of natural gas.
[0018] 2. In this solution, a sensing mechanism is installed, and the buoyancy of the buoyancy plate is used to monitor changes in the downhole water level through the buoyancy component. When the water level rises, the buoyancy plate triggers the top bar to touch the pressure switch, and the buoyancy change is recorded by the pressure sensor. This achieves real-time monitoring of downhole water level changes, providing timely early warning information for operators and facilitating the implementation of necessary emergency measures. The drive motor in the sensing mechanism receives signals from the signal controller and adjusts the valve core opening in the water valve seat, thereby controlling the flow rate of the liquid extraction pipeline. This effectively prevents rapid water level rises under special circumstances, maintaining the balance and stability of the extraction system. The isolation component, through the design of the movable baffle, quickly closes the channel between the gas transmission pipe and the liquid transmission pipe when a water level rise signal is received, preventing safety accidents caused by water intrusion into the natural gas pipeline.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0029] Example 1: Please refer to Figures 1-8 A high-efficiency, energy-saving natural gas extraction device, comprising:
[0030] The production well 1 is located below the ground, with one end located in the natural gas extraction area. Multiple extraction fractures 4 are opened on the side of the lower end of the production well 1. Multiple packer bodies 5 are installed inside the production well 1 to restrict each set of extraction fractures 4. Liquid extraction pipeline 2 and natural gas pipeline 3 are installed inside the production well 1. The ends of the liquid extraction pipeline 2 and natural gas pipeline 3 located above the ground are connected to equipment for extracting liquids and gases from the well.
[0031] In operation, the production well 1 is placed below the ground, deep enough to penetrate into the natural gas extraction zone. One end of the production well is located in the natural gas-rich strata, while the other end extends to the ground to facilitate the extraction of natural gas and liquids. Subsequently, through hydraulic fracturing or other geological engineering techniques, multiple production fractures 4 are opened at the end of the production well located in the natural gas extraction zone. Then, packer bodies 5 are installed above or below each group of production fractures 4. These packers 5 are installed on one side of each group of production fractures 4 to restrict the fluid flow between the fractures, ensuring that natural gas and liquids can flow into the production well 1 along a predetermined path to restrict the fluid flow between the fractures. Then, the extraction equipment connected to the liquid extraction pipeline 2 and the natural gas pipeline 3 is activated. The liquid extraction equipment begins to extract the liquid at the bottom of the well, while the natural gas extraction equipment begins to extract the natural gas. The extracted liquid is transported to a storage tank, while the natural gas is transported to a greater distance or further processed and utilized after impurities are removed by a separator.
[0032] The above process is the basic process of current natural gas extraction.
[0033] However, in actual natural gas extraction, water clumps easily form inside the gas extraction and liquid extraction pipelines. In the conventional natural gas extraction process, the gas extraction pipeline is responsible for transporting natural gas from the well to the surface processing facilities, while the liquid extraction pipeline is responsible for draining accumulated liquids (such as water and condensate) from the well to maintain wellbore patency and extraction efficiency. However, when wellbore conditions (such as temperature and pressure) are suitable, moisture in the natural gas can combine with gas molecules to form water clumps. Once these water clumps form inside the pipeline, they quickly accumulate and block the pipeline, severely affecting gas flow and liquid drainage efficiency. Water valves, as key components for regulating fluid flow within the pipeline, directly affect the stability and efficiency of extraction operations due to the accuracy of their opening and closing. When water clumps form near or inside the valve... When these water-filled clumps form inside the gas extraction pipeline, they gradually accumulate and block the pipeline, hindering the flow of natural gas and severely affecting the extraction efficiency. Due to the blockage, the flow rate of natural gas slows down, resulting in a reduction in extraction volume. The pressure inside the pipeline may rise abnormally due to the blockage of the water-filled clumps, increasing the risk of pipeline rupture, leakage, and other safety accidents. The blockage of the water-filled clumps also increases the energy consumption of gas extraction and liquid extraction. In order to overcome the flow resistance caused by the water-filled clumps, the gas extraction equipment and liquid extraction equipment need to consume more energy to push the fluid through the pipeline, increasing the extraction cost.
[0034] Furthermore, in natural gas extraction operations, when the distance between the well bottom and the ground is too great, signal transmission delays may occur. When the well depth is too great, the signal may be attenuated and delayed during transmission. In special circumstances, such as a sudden large amount of water seepage downhole, the water level may rise rapidly. Due to the signal transmission delay, the ground operators may not receive the alarm signal of rising water level in time. As a result, the staff may not be able to take necessary emergency measures immediately, such as stopping the extraction of natural gas to prevent the water from rising further. If the water is not controlled in time, it may continue to rise and eventually infiltrate the gas extraction pipeline located above the water extraction pipeline. The internal structure and materials of the gas extraction pipeline are not capable of withstanding large amounts of liquid pressure. The intrusion of water will not only block the pipeline and affect the normal flow of natural gas, but may also damage the pipeline structure and cause serious safety accidents such as leaks or explosions.
[0035] Therefore, based on the above problem, we first designed an anti-caking mechanism, which consists of an adjustment component and a liquid removal component. The adjustment component includes: a pumping head pipe 6, which is located inside the production well 1 and within the natural gas extraction area. Multiple fixed ring frames 18 are provided on the inner side surface of the pumping head pipe 6. A heater 19 is provided between every two fixed ring frames 18. A trigger slot 20 is provided on the side surface at the center of the fixed ring frame 18. A liftable central frame 21 is also provided at the center of the fixed ring frame 18. Two sliding blocks 26 are provided inside the trigger slot 20. A connecting shrink block 25 is provided on one side surface of the sliding block 26. The other end of the connecting shrink block 25 is fixedly connected to one side surface of the central frame 21. A fan blade 28 is provided at the center of the central frame 21.
[0036] In use, natural gas carrying water vapor and liquid needs to enter the extraction head pipe 6 before being extracted. After the liquid and natural gas enter the extraction head pipe 6, the heater 19 is activated and heats the gas and liquid in the pipeline. After entering the extraction head pipe 6, the gas is transported forward through the center of the fixed ring frame 18, while the liquid is transported from below the fixed ring frame 18. The fan blade 28 rotates with the airflow as the natural gas passes through. Through the connecting shrink block 25, it drives the central frame 21 and its buoyancy plate 27 and trigger top bar 22 to vibrate slightly. This vibration helps to break up small water clumps that have formed, preventing them from accumulating and clogging the pipeline. The fan blade 28 can also rotate the airflow into a vortex state, which can increase the transmission speed and also use the airflow to evenly cover the interior of the extraction head pipe 6 with the heat generated by the heater 19, and reduce the possibility of water vapor condensing into water clumps due to low temperature.
[0037] The liquid removal assembly includes: a separating sleeve 15, one side surface of which is fixedly connected to one side surface of the extraction head tube 6; one side surface of the separating sleeve 15 has an opening communicating with the interior of the extraction head tube 6; a separating plate 34 is fixedly installed at the center of the interior of the separating sleeve 15; a liquid passage 33 is located below the separating plate 34; a temperature guide frame 29 is fixedly installed on one side surface of the separating plate 34; a top heat dissipation plate 14 is fixedly installed on the upper surface of the temperature guide frame 29; and both ends of the temperature guide frame 29 are fixedly... A heat dissipation side plate 16 is fixedly installed. Multiple movable air passage plates 30 are provided at the center of the temperature guide frame 29. A torsion spring is provided at the connection between the air passage plate 30 and the temperature guide frame 29. A leak baffle 35 is also provided on the side surface of the temperature guide frame 29 to cover the leaks at both ends of the air passage plate 30. An inclined baffle 31 for cooperating with the temperature guide frame 29 is fixedly installed at the center of the dividing sleeve 15. A drain outlet 32 communicating with the liquid passage 33 is opened on one side of the inclined baffle 31.
[0038] The liquid separation assembly separates the gas and liquid transport paths through the partition plate 34 inside the partition sleeve 15. When the gas enters the upper part and is transported through the gas-passing movable plate 30, the gas-passing movable plate 30 rotates with the torsion spring due to the gas impact and remains open, while the liquid flows down along the liquid passage 33. When the gas passes through the gas-passing movable plate 30, the temperature guide frame 29, under the combined action of the heat dissipation side plate 16 and the top heat dissipation plate 14, absorbs the lower temperature in the production well 1 and conducts the temperature to the gas-passing movable plate 30. Both the temperature guide frame 29 and the gas-passing movable plate 30 are made of metals with high thermal conductivity, such as copper. When the air passes through the gas flow plate 30, the air, which has been heated by the heater 19, comes into contact with the cooler gas flow plate 30. The water vapor in the air loses energy and begins to condense on the surface of the gas flow plate 30, forming small water droplets or dew. The water then slides down the slope of the gas flow plate 30 and falls into the liquid passage 33 through the drain outlet 32, and is transported away with the liquid below. This method reduces the moisture carried in the natural gas, further reducing the possibility of it condensing into water condensate inside the natural gas pipeline 3, which could affect the natural gas transmission operation.
[0039] Meanwhile, based on the aforementioned issues, we also designed a sensing mechanism. This mechanism consists of a buoyancy component and an isolation component. The buoyancy component includes multiple reset retraction blocks 24, which are respectively disposed on the upper and lower surfaces of the central frame 21. A trigger top bar 22 is connected to the upper surface of the central frame 21 via the reset retraction blocks 24. A touch switch cooperating with the trigger top bar 22 is installed inside the trigger slot 20. A buoyancy plate 27 is also connected to the bottom surface of the central frame 21 via the reset retraction blocks 24. A pressure sensor 23 is installed between the trigger top bar 22 and the buoyancy plate 27. The buoyancy plate 27 is a hollow structure with strong buoyancy, allowing liquid to pass through. A water valve seat 7 is also provided in the middle section of the extraction pipeline 2. Both ends of the water valve seat 7 are provided with pipe connection ports 43 that are connected to the liquid extraction pipeline 2. A valve core is provided inside the pipe connection port 43. A rotatable force-receiving gear plate 44 is provided on the upper surface of the valve core. A protective sealing box 42 is also provided on the upper surface of the water valve seat 7. A drive motor 46 is provided inside the protective sealing box 42. A signal controller 47 is provided on one side surface of the drive motor 46. There is an electrical connection between the signal controller 47 and the pressure sensor 23. A drive gear plate 45 is provided on the output end of the upper surface of the drive motor 46. The drive gear plate 45 and the force-receiving gear plate 44 are in a meshing state.
[0040] The buoyancy assembly uses the buoyancy characteristics of the buoyancy plate 27 to monitor changes in the downhole water level. When the water level rises, the buoyancy plate 27 floats up and drives the fan blade 28 to rise, preventing its rotation from being restricted due to contact with the liquid. The reset contraction block 24 drives the trigger top bar 22 to touch the pressure switch. At the same time, the pressure sensor 23 records the change in buoyancy on the buoyancy plate 27. This signal is transmitted to the drive motor 46 through the signal controller 47. The drive motor 46 starts and adjusts the valve core opening in the water valve seat 7 through the meshing of the drive gear 45 and the force-bearing gear 44, thereby controlling the flow rate of the liquid extraction pipeline 2 and preventing the water level from rising rapidly under special circumstances.
[0041] The isolation assembly includes: an adjustment box 11, one side surface of which is fixedly connected to one side surface of the partition sleeve 15; a gas transmission pipe 9 and a liquid transmission pipe 10 are provided at the other end of the adjustment box 11; each end of the gas transmission pipe 9 and the liquid transmission pipe 10 is provided with a pipe joint 8, which is respectively connected to one end of the liquid extraction pipe 2 and the natural gas pipe 3; a fixed partition 36 and a movable partition 38 are provided at the center of the adjustment box 11; small drive shafts 39 for driving the movable partition 38 are provided on both sides of the movable partition 38; and signal drivers 12 are provided on both sides of the adjustment box 11. There is an electrical connection between the small drive shaft 39 and the trigger slot 20, and the internal contact switch. The end of the regulating box 11 connected to the partition sleeve 15 is provided with a limiting baffle 37 and a bottom limiting block 40. The limiting baffle 37 and the bottom limiting block 40 limit the rotation range of the movable partition 38 when it rotates. The bottom and top surfaces of the regulating box 11 are provided with a power generation rotating plate 41. The upper and lower surfaces of the regulating box 11 are provided with a battery 13. There is an electrical connection between the power generation rotating plate 41 and the battery 13. The side surface of the battery 13 is connected to the signal driver 12 through a connecting cable 17.
[0042] The isolation component achieves the effect of sealing the inlet of the natural gas pipeline 3 when the liquid level rises through the movable baffle 38 inside the regulating box 11. When the water level rise signal is triggered, the signal driver 12 receives the signal and drives the movable baffle 38 to rotate upward through the small drive shaft 39, closing the channel between the gas transmission pipe 9 and the liquid transmission pipe 10 to prevent water from entering the natural gas pipeline 3. At the same time, the power generation rotating plate 41 can rotate under the force during operation according to the pumping of natural gas and liquid to charge the battery 13, ensuring that the electronic equipment such as the signal driver 12 has sufficient power supply in emergency situations. The limiting baffle 37 and the bottom limiting block 40 ensure that the movable baffle 38 rotates within the specified range to avoid excessive rotation that could damage the equipment.
[0043] The working principle of this invention is:
[0044] In operation, the production well 1 is placed below the ground, deep enough to penetrate into the natural gas extraction zone. One end of the production well is located in the natural gas-rich strata, while the other end extends to the ground to facilitate the extraction of natural gas and liquids. Subsequently, through hydraulic fracturing or other geological engineering techniques, multiple production fractures 4 are opened at the end of the production well 1 located in the natural gas extraction zone. Then, packer bodies 5 are installed above or below each group of production fractures 4. These packers 5 are installed on one side of each group of production fractures 4 to restrict the fluid flow between the fractures, ensuring that natural gas and liquids can flow into the production well 1 along a predetermined path to restrict the fluid flow between the fractures. Then, the extraction equipment connected to the liquid extraction pipeline 2 and the natural gas pipeline 3 is started.
[0045] In use, before natural gas carrying water vapor and liquid is extracted, it needs to enter the extraction head pipe 6. After the liquid and natural gas enter the extraction head pipe 6, the heater 19 is activated and heats the gas and liquid in the pipeline. After the gas enters the extraction head pipe 6, it is transported forward through the center of the fixed ring frame 18, while the liquid is transported from below the fixed ring frame 18. The fan blade 28 rotates with the airflow when the natural gas passes through. Through the connecting shrink block 25, it drives the central frame 21 and its buoyancy plate 27 and trigger top bar 22 to vibrate slightly. This vibration helps to break up the small water clumps that have formed, preventing them from accumulating and blocking the pipeline. The fan blade 28 can also rotate the airflow into a vortex state, which can increase the transmission speed and use the airflow to evenly cover the interior of the extraction head pipe 6 with the heat generated by the heater 19, and reduce the possibility of water vapor condensing into water clumps due to low temperature.
[0046] The liquid separation assembly separates the gas and liquid transport paths through the partition plate 34 inside the partition sleeve 15. When the gas enters the upper part and is transported through the gas-passing movable plate 30, the gas-passing movable plate 30 rotates with the torsion spring due to the gas impact and remains open, while the liquid flows down along the liquid passage 33. When the gas passes through the gas-passing movable plate 30, the temperature guide frame 29, under the combined action of the heat dissipation side plate 16 and the top heat dissipation plate 14, absorbs the lower temperature in the production well 1 and conducts the temperature to the gas-passing movable plate 30. Both the temperature guide frame 29 and the gas-passing movable plate 30 are made of metals with high thermal conductivity, such as copper. When the air passes through the gas flow plate 30, the air, which has been heated by the heater 19, comes into contact with the cooler gas flow plate 30. The water vapor in the air loses energy and begins to condense on the surface of the gas flow plate 30, forming small water droplets or dew. The water then slides down the slope of the gas flow plate 30 and falls into the liquid passage 33 through the drain 32, and is transported away with the liquid below. This method reduces the moisture carried in the natural gas, further reducing the possibility of it condensing into water condensate inside the natural gas pipeline 3, which could affect the natural gas transmission operation.
[0047] The buoyancy assembly uses the buoyancy characteristics of the buoyancy plate 27 to monitor changes in the downhole water level. When the water level rises, the buoyancy plate 27 floats up and drives the fan blade 28 to rise, preventing its rotation from being restricted due to contact with the liquid. The reset contraction block 24 drives the trigger top bar 22 to touch the pressure switch. At the same time, the pressure sensor 23 records the change in buoyancy on the buoyancy plate 27. This signal is transmitted to the drive motor 46 through the signal controller 47. The drive motor 46 starts and adjusts the valve core opening in the water valve seat 7 through the meshing of the drive gear 45 and the force-bearing gear 44, thereby controlling the flow rate of the liquid extraction pipeline 2 and preventing the water level from rising rapidly under special circumstances.
[0048] The isolation component achieves the effect of sealing the inlet of the natural gas pipeline 3 when the liquid level rises through the movable baffle 38 inside the regulating box 11. When the water level rise signal is triggered, the signal driver 12 receives the signal and drives the movable baffle 38 to rotate upward through the small drive shaft 39, closing the channel between the gas transmission pipe 9 and the liquid transmission pipe 10 to prevent water from entering the natural gas pipeline 3. At the same time, the power generation rotating plate 41 can rotate under the force during operation according to the pumping of natural gas and liquid to charge the battery 13, ensuring that the electronic equipment such as the signal driver 12 has sufficient power supply in emergency situations. The limiting baffle 37 and the bottom limiting block 40 ensure that the movable baffle 38 rotates within the specified range to avoid excessive rotation that could damage the equipment.
