    Mesozoic in the eastern sea area of the northern margin of the South China Sea and its significance for oil/gas exploration

    • 摘要: 华南大陆南缘和台湾地区发育的中生代海相地层揭示,该区晚三叠世—白垩纪时曾遭受2次海侵。从海水入侵方向分析,南海北缘东部的海区也相应地发育2套中生代海相沉积岩系。地震资料和钻井资料证实,本区珠江口盆地潮汕坳陷和台西南盆地发育巨厚的中生界,上三叠统—下侏罗统以暗色页岩为主,代表水体宽阔、环境稳定的深海相沉积;下白垩统岩性以砂页岩为主,代表环境变化较大的浅海相和海陆过渡相沉积。上三叠统—下侏罗统与下白垩统之间为角度不整合接触。该区中生代地层具有优越的生、储、盖组合和构造圈闭条件以及油气生成、聚集和保存条件,油气资源前景良好。

       

      Abstract: Mesozoic marine strata developed on the southern margin of the South China continent and the Taiwan area reveal that two marine invasions occurred in this region from the Late Triassic to Cretaceous. From an analysis of the direction of seawater invasion,
