摘　　要：以塔里木油田东河1区块地层作为研究对象,将采油井到注气井间划分为5个相带——原油相带、前缘过渡带、混相带、两相带、气相带。通过理论计算和PR状态方程校正,建立注气混相理论计算模型,得到前缘过渡带、混相带、两相带中天然气、原油等物性变化情况。与实际生产井对比发现,计算结果与实际生产变化趋势一致。Taking DH1 block of Tarim Oilfield as the research object,five facies zones are divided from gas injection well to production well,crude oil phase zone,front transition zone,miscible zone,two-phase zone,gas phase zone.Through theoretical calculation and correction of state equation,the theoretical calculation model of gas injection miscibility is established,and the changes of natural gas and crude oil properties in front transition zone,miscible zone and two-phase zone are obtained.Compared with the actual single well,the calculated results are consistent with the actual production trend.
