摘要
川东地区已开发气田大多进入开发中后期,气体中H_2S、CO_2等腐蚀介质易致井下油管柱出现腐蚀,破坏井筒完整性。针对低压高渗无水气井在常规维护作业时面临的压井液漏失严重、返排及复产困难等技术难题,提出暂堵剂堵漏压井、解堵酸化和压缩机向地层注气开井复产相结合的采油气工艺。
As most of the gas fields in east Sichuan have entered the middle and late stages of development,the existence of hydrogen sulfide,carbon dioxide and other corrosive media has resulted in different corrosion of the tubes and greatly damaged the wellbore integrity. Based on the problems of low pressure high permeability and no water gas well in routine maintenance operation,such as serious fluid loss,low flow back rate and difficulty in restoring production,this paper aims to present a novel oil and gas production technology which combines well killing with temporary plugging agents,acidizing and gas injection.
