摘要

以印度尼西亚南苏门答腊盆地为例,分析弧后裂谷盆地同沉积断裂的发育特征,盆地同沉积断裂具有幕式活动的特征,平面上呈雁列式展布。综合利用测井相、古地形分析、地震相分析,对该盆地Jabung地区Ripah油田同沉积断裂对沉积相的控制作用进行了系统研究。目的层主要以三角洲平原亚相为主,沉积微相包括河道、河道间和湖岸沼泽。3个主要油层组从下向上沉积经历了一次水进的过程,沉积相具有较好的继承性,同沉积构造对沉积具有良好的控制作用。
Taking South Sumatra basin in Indonesia for example,this paper analyzes the developing characteristics of synsedimentary faults in the back-arc rift basin.The synsedimentary faults are characterized by episodic activities and displayed in echelon on plane.On the basis of integrating log facies,paleotopography analysis and seismic facies analysis,the paper studies the controlling of the synsedimentary faults on sedimentary facies systematically in the Ripah oilfield of this basin.The target beds in study area are dominated by delta plain subfacies,and the main sedimentary microfacies are channel,overbank and swamp.The three oil-layer groups experienced a transgressive process.The sedimentary facies presents good succession.The study proves that the synsedimentary structure has good controlling on deposition.
