摘　　要：影响CO2气水交替驱开发效果的参数较多,为了得到最佳开发效果,以特高含水开发阶段的A井组为研究对象,运用数值模拟方法,对该井组CO2气水交替驱注入参数进行了优化,建立了一套CO2气水交替驱、提高采收率注入参数优化的思路和方法。结果表明:实施CO2气水交替驱能使高含水井含水率下降5~10个百分点,增加产油,并保持地层压力稳定,维持油井长时间经济有效生产。The parameters that can effect CO2-alternating-water flooding development are more.In order to obtain the optimal development effect,by taking A well group as the research object in ultra-high water cut development stage,with the numerical simulation method,the parameter optimization of CO2-alternating-water flooding has been carried out and therefore,a set of ideas and methods of CO2-alternating-water flooding and EOR have been established.The results show that the implementation of CO2-alternatingwater flooding can make high water cut decrease 5% ~10%,increase oil production,maintain a stable formation pressure and maintain economic and effective oil well production for a long time.
