中文摘要: 中国石油西南油气田公司重庆气矿在吊钟坝气田和沙坪场气田石炭系气藏实施了以气举排水采气工艺为中心的治水工程,取得了显著效果。文章对实施气举排水采气工艺初期出现的高压气源、高压气举管线输送、气田水回注等配套工程以及气举工艺运行过程中存在的问题及采取的对策,进行了分析、总结。提出了在川东石炭系气藏整体治水过程中,应推广气举排水工艺、保护好高压气源,重视高压气源管线、气田水回注和地面采气工艺流程等配套建设,建议针对性地在沙坪场气田天东90井实施增压连续气举、在吊钟坝气田池27井实施循环增压气举等措施。文章对川东地区出水气藏地层水治理工程配套建设具有一定的指导意义,同时可作为其他气田地层水治理工作的参考。
英文摘要: 

For Diaozhongba and Shapingchang gasfields in Carboniferous reservoir, East Sichuan, a water-control treatment with gas-lift drainage gas recovery as the soul was implemented and an obvious achievement has been made. This paper first analyzes the cause of high-pressure gas source occurring at the early stage of gas-lift drainage gas recovery; and then summarizes the problems and solutions existing in the high-pressure gas source pipeline transportation, gasfield water reinjection and gas-lift operation; at last presents some suggestions on the water-control treatment in Carboniferous reservoir of East Sichuan, including, to apply the gas-lift drainage technology, to protect the high-pressure gas source, to strengthen the supporting construction in high-pressure gas source pipeline, gasfield water reinjection and surface gas recovery; and to carry out a boosting continuous and a cyclic boosting gas-lift treatments for well Tiandong 90 of Shapingchang gasfield and well Chi 27 of Diaozhongba gasfield, respectively. These suggestions are available for the formation-water control in water-produced gas reservoirs of East Sichuan. In addition, they might be references for other gasfields.
