高邮凹陷北斜坡阜三段储层发育不均,油气运移路径复杂。通过细分砂层组,开展精细沉积微相研究,并结合大量油气显示资料综合分析了砂体展布及油气运移路径。结果表明,研究区阜三段各砂层组发育3——5支三角洲前缘水下分支河道,水下分支河道和河口坝微相砂体物性较好,其展布控制着优质储层的分布。油气运移路径在内、外坡带差异明显,在内坡带,油气运移受控于水下分支河道砂体的展布;在外坡带,油气运移则受构造和水下分支河道砂体的双重控制。因此,在内、外坡带须采取不同的勘探策略。
The reservoir in the third member of Fulu Section of North Slope of Gaoyou Sag is unevenly developed with complicated oil and gas migration paths. Fine sandstone microfacies are studied by fine sandstone grouping, and the sand body distribution and hydrocarbon migration paths are comprehensively analyzed based on a large amount of oil and gas display data. The results show that 3 - 5 submarine delta front submarine channels, submarine submarine channels and Hekouou micro-facies sandbodies are developed in each sand layer of Fu 3 Member of the study area, and the distribution of which is controlled by the quality reservoir distributed. In the outer slope zone, the hydrocarbon migration is controlled by the distributary of underwater branch channel sand body. The migration of oil and gas in the outer slope zone is controlled by the structure and subaqueous channel sand Body double control. Therefore, different exploration strategies have to be taken on the outer slope.
