Description

Technical Field

[0002] With the continuous growth of global energy demand, natural gas, as a clean energy, occupies an increasingly important position in energy consumption. The innovation and development of natural gas extraction technology is rooted in the optimization and transformation of the global energy structure and the urgent need for environmental protection. As the proportion of natural gas as a clean energy 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 defects. During the natural gas extraction process, due to the suitable temperature, pressure and other conditions in the wellbore, the water vapor in the natural gas easily combines with the gas molecules to form water bodies. These water bodies quickly accumulate inside the gas extraction pipeline and the liquid extraction pipeline, seriously blocking the pipeline, resulting in a significant reduction in the fluidity of natural gas and liquid, and the extraction efficiency is therefore seriously affected. Once water bodies are formed, in order to ensure normal extraction efficiency, it is necessary to increase the energy output of the equipment, resulting in increased energy consumption during the extraction process. In subsequent processing, a lot of time and resources are often required for cleaning, which not only increases the extraction cost, but may also cause safety accidents. Summary of the invention

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Example 1: Please refer to Figures 1 to 8 , a highly efficient energy-saving device for extracting natural gas, comprising, A production well 1, the production well 1 is arranged below the ground, one end of which is located in a natural gas extraction area, a plurality of production cracks 4 are opened on the side of the lower end of the production well 1, a plurality of packer bodies 5 for limiting each group of production cracks 4 are arranged inside the production well 1, a liquid extraction pipeline 2 and a natural gas pipeline 3 are arranged inside the production well 1, and the ends of the liquid extraction pipeline 2 and the natural gas pipeline 3 located above the ground are both connected to equipment for extracting liquid and gas from underground; When in use, the production well 1 is placed below the ground at a depth sufficient to penetrate into the natural gas extraction area. One end of the production well is located in a natural gas-rich stratum, while the other end extends to the ground to facilitate the extraction of natural gas and liquid. Subsequently, multiple production cracks 4 are opened at one end of the production well 1 located in the natural gas extraction area through hydraulic fracturing or other geological engineering techniques. Then, a packer body 5 is installed above or below each group of production cracks 4. These packers 5 are installed on one side of each group of production cracks 4 to limit the flow of fluid between the cracks, ensuring that natural gas and liquid can flow into the production well 1 along a predetermined path to limit the flow of fluid between the cracks. Subsequently, the extraction equipment connected to the liquid extraction pipeline 2 and the natural gas pipeline 3 is started, and the liquid extraction equipment starts to extract liquid from the bottom of the well, while the natural gas extraction equipment starts to extract natural gas. The extracted liquid is transported to a liquid storage tank, while the natural gas is transported to a farther distance or for further processing and utilization after the impurities are removed by a separator.

[0018] The above process is the basic process of current natural gas extraction work.

[0019] However, in the actual process of natural gas extraction, water bodies are easily formed inside the gas extraction pipeline and the liquid extraction pipeline. In the conventional process of natural gas extraction, the gas extraction pipeline is responsible for transporting the natural gas underground to the ground processing facilities, while the liquid extraction pipeline is responsible for discharging the liquid accumulated in the well (such as water, condensate, etc.) to maintain the smooth flow of the wellbore and the extraction efficiency. However, when the wellbore conditions (such as temperature and pressure) are suitable, the moisture in the natural gas will combine with the gas molecules to form water bodies. Once these water bodies are formed inside the pipeline, they will quickly accumulate and block the pipeline, seriously affecting the fluidity of the gas and the discharge efficiency of the liquid. The water valve is a key component for regulating the flow of fluid in the pipeline. The accuracy of its opening and closing is directly related to the stability and efficiency of the extraction operation. When water bodies are formed near or inside the valve When the valve is blocked, it will hinder the normal operation of the valve, resulting in the inability to accurately control the opening and closing degree. This not only makes it difficult to control the removal of the liquid volume in the well, but also affects the balance of the entire production system. Once these water bodies are formed inside the gas extraction pipeline, they will gradually accumulate and block the pipeline, hindering the flow of natural gas and seriously affecting the efficiency of natural gas extraction. Due to the blockage of the pipeline, the flow rate of natural gas slows down, resulting in a reduction in the extraction volume. Due to the blocking effect of the water body, the pressure in the pipeline may increase abnormally, increasing the risk of safety accidents such as pipeline rupture and leakage. The blocking effect of the water body also increases the energy consumption of gas and liquid extraction. In order to overcome the flow resistance caused by the water body, the gas extraction equipment and liquid extraction equipment need to consume more energy to push the fluid through the pipeline, increasing the production cost; In addition, in natural gas extraction operations, when the distance between the bottom of the well and the ground is too far, 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 sudden large-scale water seepage in the well, this may cause the water level to rise rapidly. At this time, due to signal transmission delays, ground operators fail to receive the alarm signal of rising water levels in time, so the staff cannot immediately take necessary emergency measures, such as stopping natural gas extraction operations to prevent further rise of accumulated water. Once the accumulated water is not controlled in time, it may continue to rise and eventually invade the air extraction pipe above the water pumping pipe. The internal structure and materials of the air extraction pipe do not have the ability to withstand a large amount of liquid pressure. The intrusion of accumulated water will not only block the pipeline and affect the normal flow of natural gas, but may also cause damage to the pipeline structure, causing serious safety accidents such as leakage or explosion.

[0020] Therefore, based on the above problem, we first designed an anti-knot mechanism, which is composed of an adjustment component and a liquid removal component. The adjustment component includes: a pumping head pipe 6, which is located inside the mining well 1 and in the natural gas extraction area. A plurality of fixed ring frames 18 are arranged on the inner side surface of the pumping head pipe 6, and a heater 19 is arranged between every two fixed ring frames 18. A trigger card slot 20 is opened on the side surface at the center of the fixed ring frame 18, and a liftable central frame body 21 is also arranged at the center of the fixed ring frame 18. Two slidable sliding blocks 26 are arranged inside the trigger card slot 20, and a connecting shrinking block 25 is arranged on one side surface of the sliding block 26. The other end of the connecting shrinking block 25 is fixedly connected to one side surface of the central frame body 21, and a fan blade 28 is arranged at the center of the central frame body 21; When in use, before the natural gas carrying water vapor and liquid is extracted, they all need to enter the pumping head pipe 6. After the liquid and natural gas enter the pumping head pipe 6, the heater 19 is started and heats the gas and liquid in the pipeline. After entering the pumping head pipe 6, the gas is transported forward through the center of the fixed ring frame 18, while the liquid is transported from the bottom of the fixed ring frame 18. The fan blades 28 rotate with the airflow when the natural gas passes through, and the central frame 21 and the buoyancy plate 27 and the trigger top strip 22 thereon are driven to vibrate slightly by connecting the contraction block 25. This vibration helps to break up the small-scale water bodies that have been formed to prevent them from accumulating and clogging the pipeline. The airflow can be rotated into a vortex state through the fan blades 28. While increasing the transmission speed, the flow of wind can also be used to evenly cover the heat generated by the heater 19 to the inside of the pumping head pipe 6, and reduce the possibility of water vapor condensing into water bodies due to low temperature conditions.

[0021] The liquid removal assembly includes: a separation sleeve 15, one side surface of the separation sleeve 15 is fixedly connected to one side surface of the pumping head pipe 6, one side surface of the separation sleeve 15 is provided with a through hole communicating with the inside of the pumping head pipe 6, a separation plate 34 is fixedly installed at the center of the interior of the separation sleeve 15, the lower part of the separation plate 34 is a liquid passage 33, one side surface of the separation plate 34 is fixedly installed with a temperature conducting frame 29, the upper surface of the temperature conducting frame 29 is fixedly installed with a top heat sink 14, and both ends of the temperature conducting frame 29 are fixed. A heat dissipation side plate 16 is fixedly installed, a plurality of movable air-passing movable plates 30 are arranged at the center of the temperature conducting frame 29, a torsion spring is arranged at the connection between the air-passing movable plates 30 and the temperature conducting frame 29, and a leakage baffle 35 for shielding the leakage at both ends of the air-passing movable plates 30 is also arranged on the side surface of the temperature conducting frame 29, and an oblique baffle 31 for cooperating with the temperature conducting frame 29 is fixedly installed at the center of the separation sleeve 15, and a drain port 32 connected to the liquid passage 33 is opened on one side of the oblique baffle 31; The liquid removal assembly separates the transport tracks of gas and liquid through the partition plate 34 in 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 impact of the gas and remains in an open state, while the liquid flows down along the liquid passage 33. When the gas is transported through the gas-passing movable plate 30, the heat-conducting frame 29 absorbs the lower temperature in the mining well 1 under the joint action of the heat-dissipating side plate 16 and the top heat-dissipating plate 14, and conducts the temperature to the gas-passing movable plate 30. The heat-conducting frame 29 and the gas-passing movable plate 30 are both made of metal with strong temperature conductivity, such as copper. When passing through the air moving plate 30, after the temperature is raised by the effect of the heater 19, after contacting the air moving plate 30 with a lower temperature, the air is preheated and then cooled. The water vapor in the air loses energy and begins to condense on the surface of the air moving plate 30 to form small water droplets or dewdrops, which then slide downward through the inclined surface of the air moving plate 30 and slide into the interior of the liquid channel 33 through the drain port 32 and are transported away along with the liquid below. This method reduces the moisture carried in the natural gas, and further reduces the condensation of the water body into a water body inside the natural gas pipeline 3, thereby affecting the natural gas transmission work.

[0022] At the same time, based on the previous problems, we also designed a sensing mechanism, which consists of a buoyancy component and an isolation component. The buoyancy component includes: a plurality of reset shrinkage blocks 24, which are respectively arranged on the upper and lower surfaces of the central frame 21, and the upper surface of the central frame 21 is connected to the trigger top strip 22 through the reset shrinkage blocks 24. The interior of the trigger card slot 20 is provided with a touch switch that matches the trigger top strip 22. The bottom surface of the central frame 21 is also connected to the buoyancy plate 27 through the reset shrinkage block 24. A pressure sensor 23 is arranged between the trigger top strip 22 and the buoyancy plate 27. The buoyancy plate 27 is a hollow mechanism with strong buoyancy, and the liquid 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 pipeline connection ports 43 connected to the liquid extraction pipeline 2. A valve core is provided inside the pipeline connection port 43. A rotatable force-bearing toothed disc 44 is provided on the upper surface of the valve core. A protection sealing box 42 is also provided on the upper surface of the water valve seat 7. A driving motor 46 is provided inside the protection sealing box 42. A signal controller 47 is provided on one side surface of the driving motor 46. There is an electrical connection between the signal controller 47 and the pressure sensor 23. A driving toothed disc 45 is provided on the output end of the upper surface of the driving motor 46. The driving toothed disc 45 and the force-bearing toothed disc 44 are in a meshing state. The buoyancy component uses the buoyancy characteristics of the buoyancy plate 27 to monitor the changes in the water level in the well. When the water level rises, the buoyancy plate 27 floats up and drives the fan blades 28 to rise to avoid the rotation being restricted due to contact with the liquid. The retraction block 24 is reset to drive the trigger top bar 22 to touch the touch switch. At the same time, the pressure sensor 23 records the buoyancy changes of 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 by meshing the drive gear plate 45 and the force gear plate 44, thereby controlling the flow of the liquid extraction pipeline 2 to prevent the rapid rise of the water level under special circumstances.

[0023] The isolation component includes: an adjustment box 11, one side surface of the adjustment box 11 is fixedly connected to one side surface of the separation sleeve 15, the other end of the adjustment box 11 is provided with a transmission gas pipe 9 and a transmission liquid pipe 10, the ends of the transmission gas pipe 9 and the transmission liquid pipe 10 are provided with pipe joints 8, and the two pipe joints 8 are respectively connected to one end of the liquid extraction pipeline 2 and the natural gas pipeline 3, a fixed partition 36 and a movable partition 38 are provided at the inner center of the adjustment box 11, and 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 side surfaces of the adjustment box 11, and the signal drivers There is an electrical connection between 12 and the small drive shaft 39 and the touch switch provided inside the trigger card slot 20. A limiting baffle 37 and a bottom limiting block 40 are provided at one end of the regulating box 11 connected to the separation sleeve 15. The limiting baffle 37 and the bottom limiting block 40 respectively limit the rotation range of the movable baffle 38 when the movable baffle 38 rotates. A power generation rotating plate 41 is provided on the inner bottom surface and the upper surface of the regulating box 11. A battery 13 is provided on the upper and lower surfaces of the regulating box 11. 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 the connecting cable 17. The isolation component achieves the effect of closing the inlet of the natural gas pipeline 3 when the liquid water level rises through the movable baffle 38 in 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 transmission gas pipe 9 and the transmission liquid pipe 10 to prevent accumulated water from entering the natural gas pipeline 3. At the same time, the power generation rotating plate 41 can rotate according to the force when the natural gas and liquid are pumped during operation to charge the battery 13, ensuring that the electronic equipment such as the signal driver 12 has sufficient power supply in an emergency. The limiting baffle 37 and the bottom limiting block 40 ensure that the movable baffle 38 rotates within the specified range to avoid damage to the equipment due to excessive rotation.

[0024] The working principle of the present invention is: When in use, the production well 1 is placed below the ground, and its depth is sufficient to penetrate into the natural gas extraction area. One end of the production well is located in the natural gas-rich stratum, and the other end extends to the ground to facilitate the extraction of natural gas and liquid. Subsequently, multiple production cracks 4 are opened at one end of the production well 1 located in the natural gas extraction area through hydraulic fracturing or other geological engineering technologies. Then, a packer body 5 is installed above or below each group of production cracks 4. These packers 5 are installed on one side of each group of production cracks 4 to limit the flow of fluids between the cracks, ensuring that natural gas and liquids can flow into the production well 1 along a predetermined path to limit the flow of fluids between the cracks. Then, the extraction equipment connected to the liquid extraction pipeline 2 and the natural gas pipeline 3 is started; When in use, before the natural gas carrying water vapor and liquid is extracted, they all need to enter the pumping head pipe 6. After the liquid and natural gas enter the pumping head pipe 6, the heater 19 is started and heats the gas and liquid in the pipeline. After entering the pumping head pipe 6, the gas is transported forward through the center of the fixed ring frame 18, and the liquid is transported from the bottom of the fixed ring frame 18. The fan blades 28 rotate with the airflow when the natural gas passes through, and the central frame 21 and the buoyancy plate 27 and the trigger top strip 22 thereon are driven to vibrate slightly by connecting the contraction block 25. This vibration helps to break up the small-scale water bodies that have been formed to prevent them from accumulating and clogging the pipeline. The airflow can be rotated into a vortex state through the fan blades 28. While increasing the transmission speed, the heat generated by the heater 19 can be evenly covered to the inside of the pumping head pipe 6 by the flow of wind, and the possibility of water vapor condensing into water bodies due to low temperature conditions can be reduced. The liquid removal assembly separates the transport tracks of gas and liquid through the partition plate 34 in 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 impact of the gas and remains in an open state, while the liquid flows down along the liquid passage 33. When the gas is transported through the gas-passing movable plate 30, the heat-conducting frame 29 absorbs the lower temperature in the mining well 1 under the joint action of the heat-dissipating side plate 16 and the top heat-dissipating plate 14, and conducts the temperature to the gas-passing movable plate 30. The heat-conducting frame 29 and the gas-passing movable plate 30 are both made of metal with strong temperature conductivity, such as copper. When passing through the gas moving plate 30, after the temperature is raised by the effect of the heater 19, after contacting the gas moving plate 30 with a lower temperature, the air is preheated and then cooled, and the water vapor in the air loses energy and begins to condense on the surface of the gas moving plate 30, forming small water droplets or dewdrops, which then slide downward through the inclined surface of the gas moving plate 30, and slide into the inside of the liquid channel 33 through the water outlet 32, and are transported away together with the liquid below. This method reduces the moisture carried in the natural gas, and further reduces the condensation of the water body into a water body inside the natural gas pipeline 3, thereby affecting the natural gas transmission work; The buoyancy component uses the buoyancy characteristics of the buoyancy plate 27 to monitor the change of the underground water level. When the water level rises, the buoyancy plate 27 floats up and drives the fan blades 28 to rise to avoid the rotation being restricted due to contact with the liquid. The resetting contraction block 24 drives the trigger top bar 22 to touch the touch switch. At the same time, the pressure sensor 23 records the buoyancy change of 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 by meshing the driving toothed disc 45 and the force-bearing toothed disc 44, thereby controlling the flow of the liquid extraction pipeline 2 to prevent the rapid water level rise of the accumulated water under special circumstances. The isolation component achieves the effect of closing the inlet of the natural gas pipeline 3 when the liquid water level rises through the movable baffle 38 in 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 transmission gas pipe 9 and the transmission liquid pipe 10 to prevent accumulated water from entering the natural gas pipeline 3. At the same time, the power generation rotating plate 41 can rotate according to the force when the natural gas and liquid are pumped during operation to charge the battery 13, ensuring that the electronic equipment such as the signal driver 12 has sufficient power supply in an emergency. The limiting baffle 37 and the bottom limiting block 40 ensure that the movable baffle 38 rotates within the specified range to avoid damage to the equipment due to excessive rotation.
