南海北部边缘盆地油气地质特征与勘探方向

Petroleum Geology and Exploratory Targets in Marginal Basins,Northern South China Sea

根据南海北部边缘盆地油气勘探与地质研究成果,在获取大量油气地质及地球物理和地球化学资料的基础上,对该区不同盆地油气地质特征及油气运聚成藏的区域构造地质背景与勘探方向进行了剖析与系统总结,指出了具有油气远景的主要勘探领域及方向。但由于该区整体油气勘探及研究程度尚低,油气成藏地质条件复杂,故其油气运聚规律及勘探方向,迄今仍处于探索之中。

This paper presents the petroleum exploration history and geologic research results in marginal basins of northern South China Sea, and based on the abundant geologic, geophysical and geochemical data, analyzes and summarizes the different basinal geologic features, the regional structural background for oil-gas migration and accumulation and the exploratory potentials or targets in this area. In light of low degree of prospecting and research as well as complex geologic condition for hydrocarbon accumulation, the research of hydrocarbon migration and accumulation and the exploratory direction in this area will be in further exploration.
