摘要 在对岩心、镜下薄片、测井、地震等资料观测分析的基础上,进行单井相分析、剖面相分析、砂体形态分析,对沙埝南阜三段各亚段的沉积微相进行了研究。在三角洲前缘发育区,由东北向西南方向,相带分异比较明显,由三角洲前缘的水下分流河道-河口砂坝变为前缘席状砂和前三角洲及较深水湖泊相沉积。水下分流河道和河口砂坝砂体相互连接,物性好,为储油的有利相带。 Based on the analysis of core, thin section, well log and seism data, we have done the investigation of individual well phases, plane section phases, and shapes of sand bodies, and we have drawn a conclusion that the features of the sedimentary phases, in the third number of Funing group, Shanian oil field, are that: in the delta front, sedimentary phases differentiate obviously from northeast to southwest, they are underwater distributary channels, estuary dam, sand sheet and lacustrine phases. Among these phases, the underwater distributary channels and the estuary dam are favorable phases for oil accumulation with relatively good physical property.
