摘要(Abstract)：

以南黄海盆地为研究区,以海相中—古生代地层为研究目的层,采用地震地层学研究方法,综合解释采集处理的地震剖面,结合地层发育特征,划分地震层序.结果表明:研究区可识别T8、T9、T10、T11、T12、T13、Tg等7个反射界面;自上而下将基底反射界面以上的海相地层划分为Ⅰ、Ⅱ、Ⅲ、Ⅳ、Ⅴ、Ⅵ等6个地震层序.根据地震反射特征、地层速度、重磁震联合反演和区域地质,确定地层属性分别为震旦系、寒武系—奥陶系、志留系—泥盆系、石炭系—下二叠统、上二叠统和下三叠统.根据研究区石油地质条件,南黄海盆地海相地层分布稳定,残留厚度较大,存在4套生储盖组合,具备形成大型油气藏的油气地质条件.该研究成果可为分析南黄海盆地地层结构和地质演化特征提供基础资料,对其油气勘探和资源评价具有指导意义.
