| 摘 要： | 西湖凹陷是东海陆架盆地重点生海气凹陷之一，它在新生代经历断陷，坳陷，区域抬升和区域沉降四个阶段，在纵向序列上表现为二次明显的海侵和一次海退，一次水进和一次水退。由于构造运动的不均匀性，沉积基地的起伏，多物源和水进水退多次旋回，在凹陷不同时期，不同部形成不同的沉答相，这一切与下油气的生成，聚集有着极为密切的关系。

| Abstract: | Xihu Depression is one of the important petroliferous depressions in the shelf basinof the East China Sea,Its Cenozoic history can be divided into four stages:rifting, de-pressing,regional uplifting and subsiding.Two major transgressions,a regression,a wa-ter-level rise and a fall can be seen in vertical sequence,Because of nonequilibrium of tec-tonic movement,undulating sedimentary base,multiple material sources and multiple cy-cles of water rises and falls,different sedimentary facies accur at different parts of thedepression,Oil and gas generation and accumulation are closely related to the sedimenta-ry facies. |
