Description

Technical Field

[0001] The utility model relates to the technical field of natural gas exploitation, in particular to a spiral flow drainage gas extraction device for natural gas exploitation. Background Art

[0002] Like crude oil, natural gas is also buried in closed geological structures underground. Some are stored in the same layer as crude oil, and some exist separately. For natural gas stored in the same layer as crude oil, it will be mined together with crude oil. For those with only single-phase gas, we call it a gas reservoir. Its mining method is very similar to that of crude oil, but it also has its own special features.

[0003] After searching, a Chinese patent with publication number CN214944195U discloses a drainage and gas production device, including a base, a gas-liquid separation tank is fixedly connected to the right side of the top of the base, and a filter box is connected to the left side of the gas-liquid separation tank through a pipeline. The utility model constructs a drainage and gas production device through the arrangement of the base, the gas-liquid separation tank, the gas well, the sealing cover and the air pump. The sand and gravel impurities in the water and the air are filtered through the arrangement of the filter box and the filter net to avoid the sand and gravel impurities directly entering the gas-liquid separation tank and causing the accumulation and blockage. Finally, the filter net can be cleaned of sand and gravel through the arrangement of the transmission shaft, the brush, the driven gear, the motor and the driving gear, and the sand and gravel that clogs the surface of the filter net can be cleared, thereby improving the passage rate of water and gas and increasing the efficiency of gas production.

[0004] Although the above scheme can perform gravel cleaning operations on the filter and dredge the gravel that is blocking and accumulating on the surface of the filter, it is difficult for the drainage and gas production device in the above patent to convert disordered circulating gas into spiral circulating gas. The general circulation method of gas makes gas production slow and it is difficult to make full use of the gas. For this reason, we provide a spiral flow drainage and gas production device for natural gas production to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] See also Figure 1 and Figure 2 A spiral flow drainage gas extraction device for natural gas extraction includes a first pipeline 1, the bottom of the first pipeline 1 is fixedly connected to the top of a soil body 12, the top of the soil body 12 is fixedly connected to the top of a gas-liquid separator 24, the top of the gas-liquid separator 24 is connected to an air pipeline 22, the gas-liquid separator 24 is a prior art and will not be described in detail. The setting of the gas-liquid separator 24 can effectively achieve the effect of gas-liquid separation, one end of the air pipeline 22 is connected to the top of the first pipeline 1, and a filtering structure 23 is fixedly connected to the middle of the air pipeline 22. The filtering structure 23 is a prior art and will not be described in detail. The setting of the filtering structure 23 can effectively filter impurities mixed in the gas.

[0025] See also Figure 1 and Figure 5 One side of the gas-liquid separator 24 is fixedly connected with an air outlet pipe 25, and one side of the gas-liquid separator 24 is fixedly connected with a liquid outlet pipe 26. The top of the soil body 12 is fixedly connected to the bottom of the support frame 13, and the middle part of the support frame 13 is fixedly connected with a limiting clamp 14. The middle part of the limiting clamp 14 is slidably connected to the outer circumferential surface of the guide column 15. The setting of the limiting clamp 14 can effectively provide effective support for subsequent movement. The other end of the guide column 15 is fixedly connected to one side of the first clamp 19, and the other side of the first clamp 19 is fixedly connected to one side of the rubber clamp 20. The setting of the rubber clamp 20 can effectively ensure that the first clamp 19 will not move too much, thereby causing damage to the surface of the first pipe 1.

[0026] See also Figure 5One end of the guide column 15 is fixedly connected to one side of the first baffle plate 16, and the other side of the first baffle plate 16 is fixedly connected to one side of the first handle 17. The setting of the first handle 17 facilitates the operation of the staff and improves the work efficiency. One side of the first baffle plate 16 is fixedly connected to one end of the third spring 18, and the other end of the third spring 18 is fixedly connected to one side of the limiting clamp 14. The setting of the third spring 18, utilizing the elasticity of the third spring 18 itself, can effectively pull the first baffle plate 16 to move, thereby providing a force for the subsequent tightening operation.

[0027] See also Figure 3 and Figure 5 There are two groups of limiting clamps 14, and the middle parts of the two groups of limiting clamps 14 are fixedly connected with the first column 21. The purpose of setting multiple groups of limiting clamps 14 is to make the first pipeline 1 more stable and not prone to shaking. The inner wall of the first pipeline 1 is fixedly connected with a supporting plate 2, and one end of the supporting plate 2 is fixedly connected to the outer circumferential surface of the central control disc 3. The bottom of the central control disc 3 is fixedly connected to the top of the telescopic column 10. The setting of the central control disc 3 can provide support for multiple groups of components to ensure that multiple groups of components can work normally. The outer wall of the telescopic column 10 is sleeved with a second spring 11, and the top of the second spring 11 is fixedly connected to the bottom of the central control disc 3, and the bottom of the second spring 11 is fixedly connected to the top of the lightweight plug 7. The setting of the second spring 11, using the elasticity of the second spring 11 itself, can effectively promote the movement of the lightweight plug 7, so that the lightweight plug 7 enters the position with a smaller diameter at the bottom of the first pipeline 1, thereby forming a flow limiting effect on the gas.

[0028] See also Figure 3 and Figure 4 The bottom of the telescopic column 10 is fixedly connected to the top of the lightweight block 7, the middle part of the central control disc 3 is rotatably connected to the outer circumferential surface of the first central axis 4, the top of the first central axis 4 is fixedly connected with a spiral fan blade 5, and the bottom of the first central axis 4 is fixedly connected with a first fan blade 6. Under the action of the first central axis 4, the spiral fan blade 5 and the first fan blade 6 can rotate synchronously, and the outer circumferential surface of the first central axis 4 is slidably connected to the middle part of the lightweight block 7. One side of the inner wall of the lightweight block 7 is fixedly connected to one end of the first spring 8, and the other end of the first spring 8 is fixedly connected to one side of the special-shaped push block 9. The outer wall of the special-shaped push block 9 is slidably connected to the inner wall of the lightweight block 7. The setting of the first spring 8, utilizing the elasticity of the first spring 8 itself, can effectively promote the movement of the special-shaped push block 9, so that the lightweight block 7 is more stable when limiting current.

[0029] Working principle: During natural gas extraction, gas will flow in from the bottom of the first pipeline 1, causing the first blade 6 to start rotating. The rotation of the first blade 6 will accelerate the flow rate of the gas, causing the lightweight block 7 to gradually move upward. When the lightweight block 7 reaches the specified position, the gas will flow around the lightweight block 7. At this time, the first spring 8 drives the special-shaped push block 9 to be in an extended state, and the telescopic column 10 and the second spring 11 are in a compressed state. The rotation of the first blade 6 will drive the first central axis 4 to rotate synchronously under the action of the central control disc 3, thereby rotating the spiral blade 5. When the gas passes through the spiral blade 5, the disordered circulating gas will be converted into spiral circulating gas under the action of the spiral blade 5, thereby accelerating the gas to pass through the gas pipe 22 into the filter structure 23 for filtration, and finally enter the gas-liquid separator 24 to complete the gas-liquid separation effect. In the process of gas flow, the gas can be fully utilized and the circulation rate can be improved.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
