摘　　要：M油田位于乍得Bongor盆地北部斜坡带,沉积体系中普遍存在砂泥岩薄互层现象,砂体较薄,常规储层预测技术不能满足油田开发的需要。基于地震沉积分析方法,通过90°相位化与地震分频对资料进行处理,采用地层等时切片技术对主要目的层砂体展布开展分析,精细刻画出砂体的分布范围,达到了研究区薄储层砂体平面展布预测的目的。M oilfield is located in the northern slope zone of Bongor basin in Chad. The target formation is mainly composed of the thin sand-shale interbed. Conventional reservoir prediction technology cannot meet the needs of oilfield development. Based on seismic deposition analysis method, using the 90-degree phase shift and seismic frequency division process seismic data, adopting the stratigraphic isochronous slicing technology analysis the main purpose layer sand body distributions, the distributions of sand body were well described. The above method is effective in predicting the plane distribution of thin reservoir sand body.
