摘　　要：中国气田所处地质条件复杂,再加上长期开采后气井内部出现积液积水的情况,严重影响气井的开采产量与寿命。同时,长时间存在的积液等可能会对天然气产生损害和污染。积液诊断和排水采气工艺技术作为克服这些问题的技术手段,是气田开发面临的重大课题。文章针对页岩气井积液诊断及排水采气工艺技术进行分析,采用案例借鉴、文献总结等方法,从页岩气井积液分析入手,指出页岩气井积液诊断技术,阐述排水采气工艺技术。The geological conditions of gas f ields in China are complex,coupled with the accumulation of liquid and water inside gas wells after long-term mining,which seriously affects the production and lifespan of gas wells.At the same time,long�term accumulation of liquid and other substances may cause damage and pollution to natural gas.Liquid accumulation diagnosis and drainage gas production technology,as technical means to overcome these problems,are major issues faced by gas f ield development.This paper analyzes the diagnosis of fluid accumulation in shale gas wells and drainage gas production technology,uses case reference,literature summary and other methods,starting with the analysis of fluid accumulation in shale gas wells,points out the diagnosis technology of fluid accumulation in shale gas wells,and describes the drainage gas production technology.
