摘　　要：根据目前已公开发表的资料 ,对中国南海构造框架、盆地演化等区域地质特征进行综合分析 ,在此基础上 ,重点对南海地层结构、生储盖特征等进行综合归纳。认为南海基底由古老基底和古特提斯沉积层组成 ,南海扩张后形成的沉积盖层主要是新生界 ,但大部分盆地E1 ～E2 不发育。在生储盖方面 ,E31 ～N1 2 为主力生油层 ;E31 ～N2 为主力储层 ,另外 ,基岩也是重要储层类型 ;区域盖层主要是上新统和更新统海相泥岩 。According to the published data, this paper analyzes the structure frame, basin evolution, and stratigraphic structure in South China Sea, and then more attention was paid to the characters of source rocks, reservoirs and cap formations. The base stratum includes age-old basement and sedimentary stratum of the Ancient Tethys Ocean. The sedimentary cover formed after the South China Sea expansion was the Cenozoic and E_1( E_2 was lack in most basins. E_3~1～N_1~2 are main source rocks; E_3~1～N_2 and the basement rocks are the main reservoirs; the region covers are the marine mudstone in the Pliocene and Pleistocene, and the foraminiferal shale in the early Miocene.
