摘　　要：沙四上—沙三下亚段近岸水下扇是利津油田目前主要的勘探目标。本文针对扇体发育控制因素、储层分布规律进行的研究表明,扇体展布范围受湖盆演化、古地貌特点及边界断裂类型控制;结合各类分析化验资料,研究扇体储层微观特征及其成岩演化,确定其处于晚成岩A期,主要经历了压实、胶结及溶蚀作用;在此基础上明确了影响储集性能的主要因素为岩石的结构、泥质杂基含量和成岩作用。Upper Es_4~ Lower Es_3 near-shore submarine fans are major exploring targets currently in Lijin oilfield.In the paper,the study of factors,controlling fans development and rule of reservoir distribution, showed the fans distribution range is controlled by lake basin evolution, palaeogeomorphic feature and border fault pattern. In combination with various analytic and laboratory data, the study of microscopic feature and diagenesis evolution of reservoir determined the reservoir is in A stage of post diagenesis and has mainly involved compaction, cementation and dissolution. On that bases, the main factors affecting reservoir property are clarified, that are structures of rocks, shale content and diagenesis.
