惠民凹陷东部区域性走滑断裂构造系统的发现和意义
|
摘要
惠民凹陷东部地区油气勘探程度相对较低,岩浆活动剧烈,深部地质构造复杂。为此,通过岩石物性特征的研究和引起重、磁异常的地质因素分析,将重、磁、震综合地球物理解释技术应用于解决盆地深层地质构造问题,确定了重力和磁力异常在研究区的分布特征,结合地震资料解释发现了近SN向延伸的滨县-高青-博山区域性右旋走滑断裂构造系统和NNW向延伸的白桥-文祖区域性左旋走滑断裂构造系统。这两条区域性走滑断裂构造系统对本区中新生代构造格局具有重要控制作用,并控制了研究区内线性分布的火山活动和幔源CO2气的分布。
The extent of exploration of oil and gas in eastern Huimin sag is comparatively low, since the sag is characterized by strong volcanic activity and complicated geologic structures in deep levels. Based on research of the physical characters of the rocks and analysis of main geologic factors which resulted in gravitational anomaly and magnetic anomaly, the geophysical interpretation technology for integrated gravity, magnetic and seismic exploration has been applied to study of the geology and tectonics in the deep level of the basin, and the features of distribution of gravity and magnetic anomaly in the area have been determined. In combination with interpretation of seismic data, a near-NS-trending Binxian-Gaoqing-Boshan regional dextral strike slip fracture and a NNW-trending Baiqiao-Wenzu regional sinistral strike slip fracture have been identified. The two regional strike slip fracture systems control the Mesozoic and Cenozoic tectonic patterns in the study area, and can be used to deepen the structural 3-D interpretation of the structural patterns, volcanic activity and distribution of reservoirs of CO2 derived from the mantle.
