【摘要】 通过高精度三维地震解释、钻井、岩心、薄片和测井等资料分析,结合凹陷主干边界断裂及鄚州构造带内部断裂特征解析,对鄚州变换带构造属性及其控藏作用进行研究。结果表明:鄚州构造带在古近纪具有调节区域构造变形的作用,变换带历经弧形断裂系-扁豆状断块形成期、雁列状断裂系-堑垒状断块形成期和雁列状断裂系-塌陷背斜形成期3个独特的演化阶段;变换带不仅改善潜山碳酸盐岩储层物性,而且控制了古近系碎屑岩储层的展布;古近系烃源岩与变换带油气成藏相关的地质因素及地质作用具有良好的时空配置关系,形成"新生古储型"和"自生自储自盖型"两种油气聚集模式。更多还原

【Abstract】 The tectonic attributes and controlling factors were studied through the analysis of high-precision 3D seismic,drilling,core,slice,logging data and the fracture characteristics of main boundary faults and faults inside Maozhou tectonic belt.The results show that Maozhou tectonic belt has the function of adjusting regional tectonic deformation in Paleogene.Maozhou transition zone experiences three evolution stages which include arc fault system(kidney bean fault block)formation period,echelon fault system(graben horst fault block)formation period and echelon fault system(collapse anticline)formation period.Maozhou transition zone not only improves reservoir properties of buried hill,but also controls clastic reservoir distribution in the Paleogene.Hydrocarbon derived from the source rocks of Paleogene matches well with geological factors and geological function relating with Maozhou transition zone reservoir-forming in time and space.Therefore,two reservoir-forming modes of "new bed-generating and old bed-storing" and "self-generating,self-storing and self-sealing" are estabilshed in transition zone.更多还原
