摘　　要：为了确定红岗油田大208区扶杨油层有利储层,对扶杨油层沉积微相进行研究。以岩心观察、粒度分析、沉积构造特征和测井相分析为基础,结合区域地质背景,建立大208区扶杨油层的沉积模式,确定该区为三角洲平原和三角洲前缘亚相沉积。在此基础上,通过横向对比,绘制了各单层的沉积微相平面展布图,详细阐述了沉积微相的展布特征和变化规律,为寻找剩余油提供了重要的地质依据。The Fuyang reservoir in Block Da208 of Honggang oilfield is studied for sedimentary microfacies in order to define favorable reservoirs. A sedimentary model has been established for Fuyang reservoir based on core data,grain size analysis,sedimentary structural features and electrofacies analysis,as well as regional geological setting. It is determined that this area comprises delta plain and delta front sedimentary subfacies. This study has presented the areal distribution of sedimentary microfacies of single layers through lateral correlation,and expounds the distribution and variation rule of the microfacies,which are important geological reference for finding remaining oil.
