【摘要】 应用层序地层学和沉积学的基本原理和方法,综合利用三维地震及钻井等资料,对福山凹陷流沙港组层序地层进行分析。在流沙港组时期识别出4个三级层序界面,界面特征明显,并划分为3个三级层序,9个体系域。受凹陷内复杂构造活动及物源供给等因素控制,流沙港组不同构造部位发育丰富多样的层序内部构成样式,可归结为4种,即断控陡坡型、多级断阶带型、挠曲坡折带型、斜坡型层序构成样式。同时指出各层序的湖扩体系域为烃源岩的主要发育期,流二段烃源岩最为发育且可作为区域盖层;高位扇三角洲前缘、低位扇以及湖底扇为该区最有利的油气聚集区带。更多还原

【Abstract】 Based on the theory and technology of sequence stratigraphy,and using borehole and 3D seismic data,etc.,the sequence strata of Liushagang Fm（Els） in Fushan sag have been studied.Four 3^rd -order sequence boundaries in Els have been identified with distinct characteristics;Els can be divided into three 3^rd-order sequence and 9 system tracts.Under the control of complex tectonic movement and provenance supply,multiple kinds of sequence architecture developed in different tectonic units,which can be extracted into four types,fault controlling type,multi-stage fault terrace type,flexure break type,and gentle slope break type.The extending systems tract is the main developed period for source rocks.The highstand fan delta front,lowstand fan and sub-lacustrine fan can be the most favorable targets in this area.更多还原
