摘要
综合运用测井、地震、岩芯等资料,研究阳信洼陷沙四段上亚段的储集层特征、沉积相及沉积体系分布。确定了沉积相带的划分标志,划分出河流三角洲、扇三角洲、湖泊等三种沉积体系。分析了沉积体系与含油气性的关系,指出了勘探方向。
By using log data,seismic data and drilling core data,characteristics of reservoir bed,sedimentary facies and distribution of sedimentary system of upper Es4 in Yangxin subsag are studied.Criteria to classify sedimentary facies are determined,and sedimentary systems in Yangxin sabsag are divided into river dominated delta,fan delta and lacustrine sedimentary system.Relationship between sedimentary system and oil-gas bearing conditions is analyzed.And oil-gas exploration orientation is pointed out.
