摘　　要：重力流水道砂体是大港滩海区重要的储油砂体类型。通过对重力流水道砂体的粒度特征、沉积构造、沉积层序、岩相分布及砂体与沉积相带展布特点的分析 ,初步探讨了大港滩海区重力流沉积的成因 ,明确了有利储集相带展布 。Gravity flow channel sandbody is one of the most important reservoir in Dagang Oilfield.This paper distinguishes turbid flow channel deposits by grain size distribution curves,sedimentary structure and sequence,graded facies and so on,and discusses the origin of channel deposits by analyzing its lithofacies distribution.
