南黄海海域生储盖层特征及油气远景评价

根据近年来新取得的资料,结合前人的研究成果,对南黄海海域的生储盖层特征进行了综合研究。古生界、中生界海相地层为南黄海海域的主力烃源岩,从构造运动和沉积发育情况分析,将南黄海海域的古生界、中生界海相地层生成油气的成藏过程划分为三叠纪印支运动前、侏罗纪—白垩纪、古近纪和新近纪4个阶段。通过对生储盖层的特征分析,说明南黄海古生界、中生界海相地层油气资源具有开发前景。在对南黄海盆地海相中生界、古生界烃源条件和后期保存条件研究的基础上,预测了盆地内海相油气资源的有利运聚区,为南黄海海域的油气勘探及研究工作提供了依据,对我国新的海上油气开发及部署作出了贡献。

Characteristics of source-reservoir-cap rock and hydrocarbon prospect evaluation in the South Yellow Sea

According to new data and previous research results in recent years, the characteristics of reservoir and caprock of the South Yellow Sea were comprehensively investigated. Ancient marine Mesozoic strata were chosen as the main hydrocarbon source rocks. Based on the tectonic movement and sedimentary development analysis, the hydrocarbon accumulation in marine Mesozoic strata of South Yellow Sea is divided into four stages: stages before Triassic indosinian movement, Jurassic-Cretaceous, Paleogene and Neogene. This paper shows that ancient marine Mesozoic strata in the South Yellow Sea have the prospect of hydrocarbon development, through the analysis of the characteristics of the reservoir. The favorable marine oil and gas resources accumulation were forecasted based on the study of the hydrocarbon source and preservation condition in later period. This study provides the basis for oil and gas exploration and makes contribution to the deployment of new offshore oil and gas in China.
