摘　　要：在综合凝析气藏流体相态特性资料及现场测试报告的基础上,总结出凝析气藏流体样品恢复的3种方法:①常规的分离器油气样品在露点压力下配样的样品恢复法;②重质组份添加法配样的样品恢复法;③凝析气藏油环平衡气样品恢复法.结合凝析气藏流体相态特性讨论了此3种样品恢复法的适用性,针对较为特殊的带油环凝析气藏——大张坨凝析气藏,采用第3种方法进行了样品恢复的实例计算,验证了该方法的适用性.In this paper, three kinds of fluid sample recovering methods are presented based on integrated research of condensate gas reservoir phase behaviors and on-site testing report. (1) Sample recovering method of oil & gas mixed at due point pressure from conventional separators. (2) Sample recovering method of oil & gas mixed by adding heavy component. (3) Sample recovering method of oil ring balanced gas from condensate gas reservoir. The applicability of these three sample-recovering methods is discussed based on condensate reservoir fluid phase behaviors. And a case history is given by the third method aimed at a special oil ring condensate gas reservoir, namely, Dazhangtuo condensate gas reservoir, which has verified it抯 applicability further more.
