摘　　要：注CO_(2)技术被视为提高采收率的有效方法,但对于自生自储的页岩气藏,该技术还未实现商业化应用。本文阐述了注CO_(2)提高页岩气采收率的机理,重点分析了注CO_(2)提高页岩气采收率的可行性,最后,结合现场试验,得出注CO_(2)提高页岩气采收率是可行的方法。CO_(2)injection technology is regarded as an effective method to improve oil recovery,but for shale gas reservoirs with self generation and self storage,this technology has not yet achieved commercial application.This paper expounds the mechanism of CO_(2)injection to improve the recovery of shale gas,and analyzes the feasibility of CO_(2)injection to improve the recovery of shale gas.Finally,combined with field tests,it is concluded that CO_(2)injection to improve the recovery of shale gas is a feasible method.
