中文摘要：

为了探讨南黄海中—古生界油气保存条件,开展了上下扬子中—古生界构造演化、生储盖组合等对比分析。结果显示：印支和燕山运动对南黄海中—古生界的影响大大强于上扬子四川盆地,致使三叠系残留厚度较薄;推测南黄海中—古生界盖层以泥岩为主,膏盐岩为辅,其中泥岩盖层以下寒武统、下志留统和上二叠统为主,膏盐岩盖层则以中下三叠统为主。综合研究认为,烟台坳陷和崂山隆起以下寒武统或下志留统的泥岩为主要盖层,推测可形成威远型气藏;而青岛坳陷和勿南沙隆起以上二叠统泥岩为直接盖层,中下三叠统膏盐岩为间接盖层,推测可形成五百梯型或建南型气藏。南黄海盆地间接盖层缺乏,但下古生界具有良好的生烃潜力和保存条件,因此,南黄海盆地应重视下古生界页岩气的勘探和开发。

英文摘要：

In order to reveal the preservation potential of Meso-Paleozoic hydrocarbon reservoirs in the South Yellow Sea Basin, tectonic evolution and source-reservoir-cap assembles of the Lower Yangtze are analyzed and compared with the Upper. The results show that Indosinian and Yanshan Movements are much stronger in the South Yellow Sea Basin of the Lower Yangtze than those in the Sichuan Ba- sin of the Upper Yangtze, which leads to partially missing of the Middle-Lower Triassic in the South Yellow Sea Basin. The Meso-Paleozoic caprocks in the South Yellow Sea Basin are mainly mudstone with little gypsum, including the mudstone caprocks of Lower Cambrian, Lower Silurian and Upper Permian and the gypsum eaprocks of Lower Triassic in the Yantai Depression and on the Laoshan Up- lift. And gas fields of the Weiyuan-type are possible to be discovered. The Upper Permian mudstone may he the direct caprocks and the Middle-Lower Triassic gypsum the indirect caproeks in the Qingdao Depression and Wunansha Uplift, and the gas fields of Wubaiti-type or Jiannan-type could be discov- ered there. Although the indirect caprocks are lack in South Yellow Sea Basin, hydrocarbon genera- tion and preservation potentials of Lower Paleozoic are both good for oil accumulation. Therefore, ex- ploration and development of Lower Paleozoic shale gas should not be ignored in the South Yellow Sea Basin.
