【摘要】 惠民凹陷东部地区油气勘探程度相对较低,深部地质构造复杂。本文在研究岩石物性特征的基础上,探讨了引起重、磁异常的地质因素;利用地震资料信息,深化了构造立体解释,重、磁、震综合解释,落实了深层构造格局,发现了两大基底剪切带和其伴生构造。根据幔源活动的规律,对该区构造成因机制进行初步探讨,认为该区深、浅层构造差异性明显,属"立交桥"式构造组合。更多还原

【Abstract】 The exploration extent of oil and gas is comparatively low and the geologic structures in deep formation are complex in eastern Huimin sag. The geologic factors which resulted in gravitational abnormal and magnetic abnormal are discussed based on studying rock-physical characters in this paper. The seismic data are used to deepen structural 3-D interpretation and integrated gravity, magnetic and seismic exploration interpretation, the structural patterns in the deep formation in the studying area are determined . Two major basement shear zones and associated structures were found out and the influences from the matters of mantle source were analyzed, and the forming mechanisms were primarily discussed. We consider that the differences of the structures which are in shallow and deep are obvious and are belong to "overpass" structural combination .更多还原
