在已有钻井资料上,以构造背景、沉积相分析、沉积体系三方面对东营组三段进行分析,识别出东三段主要有滨浅湖-深湖、辫状河三角洲、湖底扇三种沉积体系,按沉积时期不同先后发育在金县东三段。并从控制因素上总结,东三段沉积体系的形成主要受构造作用、古地貌作用双重控制,藉此寻找有利相带,预测储层位置。 Based on the existing data of drilling, the third member of Dongying Formation is analyzed from three aspects of tectonic setting, sedimentary facies analysis and sedimentary system. It is found that there are three main types of Dongying formation: shallow lake-deep lake, braided river delta, Sedimentary system, according to the deposition of different development successively in the East Section of Jinxian. Based on the control factors, the formation of sedimentary system in the East Third Member is mainly controlled by tectonism and palaeogeomorphology, so as to find favorable facies belt and predict the reservoir location.
