摘　　要：为建立准确的开发地质模型,利用岩心、测井及化验分析资料,详细研究了濮城油田沙河街组辫状河三角洲储层隔夹层的成因类型及分布状况。研究表明,辫状河三角洲储层隔夹层的主要沉积成因类型包括:湖泛垂积成因、河漫成因、滞流成因、废弃河道成因、前积及堤岸成因。隔夹层是控制水淹层中油水运动的主要地质因素。The model of geological exploitation was establish accurately by using information of core, logging and laboratory analysis and studying in detail the causes of type and distribution of braided river delta reservoir of Shahejie Formation in Pucheng Oilfield. The research shows that the main reservoir intercalation types in braided river delta deposition are formed by Pan-down deposit of lake, river stagnation flow, abandoned river, the former deposit and the embankment. An interlayer is the main geological factor to control the migration of oil and water in water layer.
