摘　　要：凝析气藏循环注气参数是影响循环注气采收率及经济效益的主要指标.为深入了解不同的注入参数对气藏开发效果的影响程度,针对大涝坝凝析气藏的特征开展了注气可行性研究.通过数值模拟方法研究了注入介质、注入方式、注入时机、注采比等参数对凝析气藏注气开发效果的影响,并优选了注入参数.结果表明,经过优化参数后的注气开发方式可明显提高凝析油采收率,同时可提高天然气采收率.The cyclic gas-injection parameters are the main factor of influencing the recovery factor and development benefit.For this reason,the feasibility of the cyclic gas injection in Dalaoba condensate gas reservoir is studied:the effects of the parameters of injected media,injection mode,injection opportunity,injection to production ratio etc.on the development result of the condensate gas reservoir are discussed,and the parameters are optimized.The simulation results show that the recovery factors of natural gas and condensate oil all can be increased according to the optimized parameters.
