摘要
气举排水采气在川东石炭系气藏治水中的应用越来越广泛且取得了保护气藏、延长气井无水采气期和提高采收率的良好效果。在对天东90井和池27井高压排水采气情况进行分析研究的基础上,总结了排水采气工艺在应用于川东石炭系气藏治水中取得的成效和存在的问题,提出了相关建议,为其他气井的排水采气提供了经验和技术支持。
Gas-lift drainage gas recovery has been more and more widely applied to water-control treatment in Carboniferous gas reservoirs in Eastern Sichuan Basin and has achieved good results in protecting the reservoirs,prolonging the gas production period without water and enhancing the recovery efficiency.Based on analysis of high-pressure drainage gas recovery in Tiandong 90 well and Chi 27 well,results and existing problems during gas recovery have been summarized,and some relevant suggestions have also been proposed.These provide an experience and a technical support for drainage gas recovery in other wells.
