【摘要】 伊通地堑岔路河断陷南段,在地堑西北缘断层及二号断层(F2)的制约下,主要分为梁家构造带和新安堡凹陷两个二级构造单元。根据三维地震资料进行系统的构造解析认为,该区可划分为滚动背斜带、断块隆起带和走滑断陷带三个构造带。该区沉积相类型及其展布规律主要受控于东南缘断层、西北缘断层及F2断层的构造活动。受不同的构造-沉积特征制约,形成西北缘边界断层下的断层-岩性油气藏、中央隆起带断块式油气藏、F2断层控制的构造-岩性复合油气藏。更多还原

【Abstract】 The southern part of Chaluhe fault depression of Yitong Graben,controlled by faults in northwestern graben and fault 2,can be divided into two structural units: Liangjia structural zone and Xin’ anpu depression.On the basis of systematically structural interpretation of 3D seismic data,the area can be further divided into three structural zones: rolling anticline zone,block fault uplift zone and strike slip fault depression zone.The types and distribution of sedimentary facies in the area are main controlled by tectonic activities of southeastern fault,northwestern fault and the fault 2.According to the different structural and sedimentary features,there exist three types of hydrocarbon reservoirs: fault-lithology hydrocarbon reservoir in northwestern border fault,fault-block hydrocarbon reservoir in central uplift belt and structure-lithology composite hydrocarbon reservoir controlled by the fault 2.更多还原
