【摘要】 勘探成果表明,阿克库勒凸起受长期多次构造叠加影响,具有长期生烃、多期供烃的烃源特征,古生界油气输导体系复杂。在分析输导路径、输导能力及作用的基础上,将其分成断裂型、不整合型、岩溶网络型3类输导系统。利用地震和钻井资料恢复古地貌,分析输导体系的演化及配置关系,认识油气运移的动态过程,指出区域性深大断裂是油气垂向运移的主要通道,不整合面(T74、T07、T60)的叠置是油气侧向运移的关键因素,并且油气成藏关键时刻古构造脊线的展布特征决定了油气优先运移的方向和路径。由断层-不整合面-岩溶网络组成的"层-面-网"复式输导系统相互匹配,沿构造脊线呈立体网状阶梯式运移是研究区古生界油气输导体系最鲜明的特点。更多还原

【Abstract】 The consequence of exploration shows the Akekule lobe has complicated pathway systems and resource rocks which have been providing hydrocarbon in Paleozoic due to many tectonic movements during the long period.On the basis of analyzing route,capability and function of path systems,the systems can be divided into three types,i.e.,fault,unconformity and karst network.By reconstructing the paleo tectonic structure with seismic data and well information and recognizing the dynamic process of oil-gas migration,the research points out that the local big faults are the main paths of vertical hydrocarbon transportation.The research also concludes that the superposition of unconformities(T47,T07,T06)are the key factors of horizontal hydrocarbon migration,furthermore,the geometrical formation during the critical period of hydrocarbon gathering,especially the distribution of paleo ridge,determines the predominant direction and path of hydrocarbon migration.The types of pathway systems of hydrocarbon migration by fault-unconformity-karst network along structure ridge in the form of three-dimensional ladder-shaped are the most distinct characteristic in work area.更多还原
