采用常规排水采气方法不仅在产出水的举升、处理和注入过程中需要耗费很多能量,而且增添设备所附加的资金投入也增加了采气成本,缩短了气井的经济可采寿命,同时产出水还对环境造成潜在的威胁。因此,研究气井积液机理,以便利用气井自身能量无积液连续生产。 Conventional drainage gas recovery not only consumes a lot of energy during the lifting, treatment and injection of produced water, but also increases the cost of gas recovery and the economic recoverable life of gas wells by adding additional capital investment in equipment Produced water also poses a potential environmental threat. Therefore, the study of gas well liquid accumulation mechanism, in order to make use of the gas well itself without effusion continuous production.
