南华北盆地黄口凹陷构造演化与油气勘探方向

对黄口凹陷的区域地质、地震、钻井、地球物理及地球化学等资料进行了综合分析，提出黄口凹陷的构造演化经历了5个阶段；，指出黄口凹陷内存在4套烃源岩和3套生储盖组合，其中最主要的烃源岩是石炭一二叠纪煤系；黄口凹陷油气勘探的有利地区为黄口次凹的中、西部及商丘次凹，而黄口次凹中向杨集、砀山凸起的斜坡带是油气运移聚集的有利地带．

Tectonic Evolution of Huangkou Depression and Its Petroleum Potential

The geological, seismic , geophysical as well as geo-chemical data of Huangkou Depression were analyzed. The result shows that the structural evolution of the research area has undergone 5 stages . And 4 sets of hydrocarbon source rocks and 3 sets of generation-reservoir-cap assemblages exist in the depression, of which the C -P coal measures is the most important hydrocarbon source rocks. The favorable areas for oil-gas prospecting are the secondary Shangqiu depression and the central and west parts of Huangkou depression. While the slope zone toward the Yangji and the Dangshan upheaval in the secondary Huangkou depression are the favorable zones of oil-gas migration and accumulation.
