摘　　要：塔东地区不同构造带上代表性钻井下古生界储层的流体包裹体拉曼光谱成分表明,大量液态烃、气液两相烃、含烃盐水及沥青存在于下古生界储层中,表明英吉苏凹陷曾经有过油气的生成,古城鼻隆和塔东低凸起曾经有过油气的充注。米兰1井与古城4井含烃流体包裹体拉曼成分的不同,说明它们可能具有不同的油气来源。古城4井寒武系与奥陶系储层中流体包裹体成分的明显差异,表明二者间存在流体封隔层。The examination of abundant representative fluid inclusions from the Palaeozoic hydrocarbon reservoirs in eastern Tarim Basin, Xinjiang has disclosed that the existence of liquid and gas-liquid hydrocarbon inclusions, saltwater hydrocarbon inclusions and bitumen indicates the hydrocarbon generation in the Yingjisu depression, and hydrocarbon injection on the Gucheng uplift and eastern Tarim low relief. The differences in Raman compositions of the hydrocarbon inclusions from the Milan-1 well and Gucheng-4 well suggest distinct sources of hydrocarbons. Furthermore, the compositional differences in fluid inclusions from the Gucheng-4 well suggest the existence of the confining layers between the Cambrian and Ordovician hydrocarbon reservoirs, and the Cambrian strata in the Gucheng-4 well are relatively favourable for the preservation of hydrocarbons
