| 摘 要： | 在对渤海东部海域区域构造背景分析基础上,对庙西凹陷北洼反转构造的几何学特征、反转期次、形成机制进行详尽分析,并由此探讨了反转构造对油气成藏的控制作用。庙西北洼整体上表现出明显＂顶隆、中平、下凹＂的三元结构特征,至今可能发生至少两期的构造反转,对该区的油气的生成、运移、聚集和保存带来了积极的影响,同时也带来一定的制约因素。通过综合分析,该区在新近系具有较大的勘探潜力。

| Abstract: | Based on analysis of regional tectonic background of the eastern waters of Bohai Sea, geometry characteristics, inversion times and formed mechanism of inversion tectonics in the northern sag in Miaoxi were analyzed, and the control of inversion structure on hydrocarbon accumulation was discussed. The strata in the sag show three characteristics of ＂uplift in the top, fiat in the middle, depression in the lower＂. So far, at least two times of tectonic inversion has occurred, which bring some positive effects on hydrocarbon generation, migration, accumulation and preservation, but also bring some negative effects. Through comprehensive analysis, the area in the Neogene has great exploration potential. |
