摘　　要：排水采气工艺技术作为治理气井出水的关键措施,对气田的持续稳产、增加产气量和延长生命周期具有关键作用。造成气井井底积液的原因包括完井液返排不足、气藏的开发特点以及气井间开不连续生产等因素。当前治理气井积液的技术有泡沫排水、柱塞气举、速度管柱、电潜泵、堵水等常规工艺以及高压气举、井间互联、连续油管等停产井复产工艺,研究的重点主要集中在提高气井携液能力、完善配套设备、降低实施成本、研发适应不同气藏条件的工艺技术等方面。需要根据储层地质特征、测井数据、产水规模、产气量、井筒压力损失情况等关键因素,综合考虑工艺原理、适用性、投资成本、优势与局限性,科学地选择排水采气工艺。将复产工艺与常规工艺相结合,可高效地应对实际生产问题。未来,排水采气工艺将向智能化、多学科融合、长效性与可持续性方向发展。As a key measure to control the water-producing of gas wells,drainage technology plays a key role in maintaining stable production,increasing gas production,and prolonging the life cycle of gas fields.The causes of bottom-hole liquid loading of gas wells include insufficient completion fluid flowback,gas reservoir development characteristics,and discontinuous production between gas wells.The current technologies for controlling liquid loading in gas wells include foam drainage,plunger gas lift,velocity string,electric submersible pump,water plugging,and other conventional processes,as well as high-pressure gas lift,well interconnection,coiled tubing and different processes for production resumption in none-production wells.The research focuses on improving the liquid-carrying capacity of gas wells,improving supporting equipment,reducing implementation costs,and developing technology suitable for different gas reservoir conditions.According to the key factors such as reservoir geological characteristics,logging data,water production scale,gas production,and wellbore pressure loss,the technological principle,applicability,investment cost,advantages,and limitations should be comprehensively considered to select the drainage technology scientifically.Combining production resumption and conventional processes can effectively deal with the issues during actual production.In the future,drainage technology will develop in the direction of intelligence,multidisciplinary integration,long-term effectiveness,and sustainability.
