Description

Technical Field

[0001] The present invention relates to the technical field of natural gas recovery, and particularly to an efficient water drainage and gas production device. Background Technique

[0002] Natural gas is also buried in closed geological structures underground, just like crude oil. Some are stored in the same layer as crude oil, and some exist alone. For natural gas stored in the same layer as crude oil, it will be extracted together with crude oil. Its extraction method is very similar to that of crude oil. Natural gas has a small density, so the gas column in the wellbore exerts a small pressure on the bottom of the well. It has a small viscosity and a small flow resistance in the formation and pipelines. Also, due to its large expansion coefficient, its elastic energy is large. However, because the pressure in gas wells is generally high and natural gas is a flammable and explosive gas, the pressure-bearing capacity and sealing performance requirements for the gas production wellhead device are much higher than those for the oil production wellhead device. During the extraction of natural gas, the water body in the gas well is likely to enter the pipeline, affecting the collection of natural gas, and if not treated in time, it is likely to cause erosion and damage to the pipeline.

[0003] During the existing natural gas recovery operation process, it is not possible to actively drain the water body in the natural gas well, which is likely to cause the water body to seep into the pipeline, and it is not convenient to adjust the recovery depth of natural gas according to the water level. Therefore, it does not meet the existing requirements, and for this reason, we propose an efficient water drainage and gas production device. Summary of the Invention
