摘要

南黄海盆地自开展油气勘探活动以来,一直没有大规模的油气发现,整体研究程度偏低。为实现研究区成藏有利区带的预测,在充分消化吸收前人研究的基础上,利用区域二维地震测线解释,结合野外露头剖面资料、钻井资料等,对南黄海盆地南部坳陷烃源岩的发育、构造圈闭的分布进行了研究。研究发现,南黄海盆地南部坳陷南五凹烃源岩最发育,南四凹及南七凹次之,且中新生界阜宁组为主力生烃层系,以生油为主。该研究对于南部坳陷中新生界烃源岩发育情况进行了系统评价,并预测了南五凹陷是最有利的生烃凹陷,邻近南五凹的有利构造圈闭易于成藏,优选出南部坳陷I类有利勘探区域。研究结果对南部凹陷进一步的勘探部署具有指导意义。
        Since the hydrocarbon exploration in the Southern Yellow Sea,there has been no large-scale hydrocarbon discovery and sufficient researches. In order to realize the favorable accumulation zone prediction,based on the previous researches,the development of source-rocks and the distribution of structural traps in the Southern Depression of Southern Yellow Sea were studied by using regional 2 D seismic line interpretation,field outcrop and profile data and drilling data. Research indicates that the source-rock development level from high to low is south-5 depression,followed by the south-4 and south-7 depressions in the South Depression of Southern Yellow Sea Basin. The Mesozoic and Cenozoic Funing Formation is considered as the major hydrocarbon generation stratum,which is dominated by oil generation. The Mesozoic and Cenozoic source-rock development were systematically evaluated in the South Depression,which reveals that the south-5 depression is the most favorable hydrocarbon generation depression. The favorable structural traps adjacent to the south-5 depression is favorable to hydrocarbon accumulation,and the class-I favorable exploration zones were preferred in the South Depression. This research provide certain guidance for the further hydrocarbon exploration deployment in the South Depression.
