摘　　要：锦州A油田储层的埋藏深、厚度薄、横向变化大。在分析该油田沙河街组储层敏感岩石物理参数的基础上,利用弹性参数组合的坐标旋转法预测了能够区分岩性的叠前弹性参数组合属性,所获得的岩型剖面中薄互储层的分辨率较高,指导了锦州A油田的水平井位优化部署工作,其钻井结果与已钻井的吻合程度较高。Jinzhou A Oilfield is characterized by deep burial, thin reservoirs and laterally serious change. Based on the analyses of the physical parameters of the sensitive Shahejie Formation reservoirs, the combined attributes of the prestack elastic parameters that can distinguish the lithologies are predicted with the help of the coordinate rotation method using the elastic parameter combination, thus much higher resolution of the thin interbedded reservoirs are obtained and the optimization and arrangement of the horizontal well location for the oilfield are guided, and furthermore there are pretty higher coordination between the drilled results and the other successfully drilled ones.
