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 north 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(E1m)and the Lingfeng Formation(E1l)of the Lower Tertiary.The sag was believed as an oil and gas domain by petroleum geologists.A deeper petroleum system(E1y-E1l)and a shallow complex petroleum system(E1m-E1w)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.
