| 摘 要： | 丽水西凹陷位于东海盆地台北坳陷西部,烃源岩、储集岩均属于下第三系明月峰组(E1m)和灵峰组(E1l)泥岩和砂岩.该凹陷被石油地质学家一致认为具有良好的油气勘探远景.作者以含油气系统理论为指导对其进行了全面分析,划分出深部E1y-E1l油气系统和浅部E1m-E1w复合油气系统,探讨了烃源岩生排烃与圈闭发育期的匹配关系,油气运移方式及通道,提出了油气富集规律以及油气的勘探方向和目标.

| Abstract: | The West Lishui Sag is located in the no r th of the Taibei Depression, the East China Sea Basin. Its source rocks and rese rvoir rocks are dark shales and sandstones in the Mingyuefeng Formation (E 1 m) and the Lingfeng Formation (E 1l) of the Lower Tertiary. The sag w as believed as an oil and gas domain by petroleum geologists. A deeper petroleum system (E 1y-E 1l) and a shallow complex petroleum system (E 1m -E 2w) were identified in the West Lishui Sag. The relationship between source rocks and hydrocarbon accumulation was discussed, and a model of hydrocarbon migration wa s postulated. The petroleum distribution in this sag was clearly defined and po tential targets for prtroleum exploration were pointed out. So that this study w as applicable to hydrocarbon exploration in the Easy China Sea Basin. |
