综合使用物源、古流向分析及古地貌恢复，并依据各古地貌单元对砂体分布的影响，循着各古地貌单元在盆地中的分布状况，对东濮凹陷西斜坡沙三中潜在砂体发育区进行了预测。同时结合东濮凹陷西斜坡的地质特点，对恢复古地貌的方法进行了改进。

This article predicts the potential sandbodies distribution of middle Es3 reservoir in the west slope of Dongpu Depression by synthetically analyzing the provenance, paleocurrent direction and palaeogeomorphology, based on the distribution of every palaeogeomorphology units in basin and in terms of the influence of every palaeogeomorphology units on sandbodies distribution. Simultaneously we improve the methods of building up palaeogeomorphology, combined with the geology features of the west slope of Dongpu Depression.
