摘要: 西湖凹陷春晓气田群花港组H5砂体具良好的含油气性,作者通过该储层砂体沉积层序划分对比、分布特征、沉积机制、盖层品质以及成藏机理讨论,探讨了油气富集层的优选条件,为寻找最佳勘探目的层提出见解。Abstract: H5 reservoir of Huagang Formation stored up plentiful oil/gas resources in Xihu Trough. Discussed reservoir depositional sequence contrasting, distribution,genetic mechanism,caprock character and reservoir forming mechanism of H5,This paper tries to find out some geologic conditions for outbalancing optimal oil/gas enrich layer,and puts forward particular viewpoint for deciding optimal exporting target in Xihu Trough.
