【摘要】 利用三维地震、钻/测井等资料,对渤中凹陷古近系石南地区的构造、地层及沉积进行详细解释,运用断层活动速率法,系统分析了古近系石南断层活动特征及其对沉积相的控制.结果表明:石南地区由西向东依次发育近EW、NNE、EW走向的分支断层.古近系沉积演化过程中,石南断层活动强度呈"弱—增强—减弱—最强—减弱—最弱"的变化趋势;随着断层活动速率的降低,沉积相依次为扇三角洲、冲积扇、曲流河三角洲、辫状河三角洲、滩坝等相类型.更多还原

【Abstract】 The detailed structural,stratigraphic and sedimentary interpretation of Paleogene in the studied area are carried out using three-dimensional seismic,drilling / logging data,etc.The characteristics and controlling effect of fault activity of Paleogene on sedimentary facies are analyzed.The results show that in Shinan area are developed the branch faults in the directions of close EW,NNE,EW from west to east.In the evolution of Paleogene sediments,the activity intensity of Shinan fault presents the trend of "weak-Enhancing-weakening-the strongest-weakening-the weakest".With the decreasing of fault activity rate,sedimentary facies are fan-delta or nearshore subaqueous fan,alluvial fan,meandering river delta,braided delta,beach bar and other facies.更多还原
