摘要
老爷庙地区古近系东营组发育扇三角洲、水下重力流、近岸水下扇和湖泊等沉积体系。综合研究表明,构造演化、背斜形态以及同沉积断裂对老爷庙地区东营组沉积体系的发育和分布起到主要的控制作用。其中,构造演化控制扇三角洲的发育与演化,滚动背斜决定扇三角洲平面分布,同沉积断裂主导沉积物分散体系和砂体的分布样式。老爷庙地区东营组沉积体系的主控因素的研究对该区沉积模式的建立和砂体预测具有重要指导意义。
In Dongying Formation of Laoyemiao Region,there developed of fan-delta,subaqueous gravity flow,neritic subaqueous fan and lake depositional systems.This study reveals that the tectonic evolution,anticline style and synsedimentary faults controlled the development and distribution of depositional systems in Dongying Formation.The tectonic evolution controlled the development and evolution of fan delta,and the rolling anticline controlled the plain distribution of fan delta,and the synsedimentary faults controlled sediment dispersion system and sandbodiy distribution patterns.The study of sedimentary system and key controlling factors are significant for the establishment of depositional model and for forecasting favorable sandbodies.
