重磁资料解释在地质构造推断上的应用——以渤海湾盆地A区为例
Application of Gravity and Magnetic Data Interpretation in Inference of Geological Structure——By Taking Region A in Bohai Basin for Example
摘要:
油气主要富集在地层超覆带和断裂伴生构造带，有构造成藏及岩性成藏。因此可以利用重磁资料研究断裂及构造单元，为进一步划分含油气远景区提供地球物理依据。根据断裂分布及重磁异常场的分区特征，将研究区划分为4个一级构造单元、7个二级构造单元，基本特征为东西成带、南北分块。
Abstract:
Oil and gas were mainly enriched in the stratigraphic overlap zones and fault associated structural belts. There existed structural reservoir formation and lithologic reservoir formation. Therefore, the gravity and magnetic data could be used to study the faulted and structural units to provide geophysical basis for further division of oil and gas prospective areas. According to the distribution characteristics of fracture and gravity and magnetic anomaly field, the study area is divided into 4 first order structural units and 7 second order units. Research shows that the study area is basically characterized by zoning in the east and west and block in the south and north.
