Abstract: The method is provided for the favorable sandy reservoir's prediction by the recognition of the remained accommodation in this paper. Remained accommodation is the potential area of the geomorphic low near the surface of the sequence boundary during the period of the unconformity formation. The distribution of the paleocurrent is mainly controlled by the remained accommodation, the coarse sediments are transferred along the remained accommodation from the geomorphic high to the basin as the result of truncation, which are maintained in the area of the remained accommodation below the bypassing surface. As a result, the remained accommodation below the bypassing surface is the most favorable place for the high quality reservoirs to develop.Themethod had played a role in the prediction and high-effectiveness development of Sulige gasfield, and made a success in disposing wells in remained accommodation area over sequence surface. The application results show that the method of the remained accommodation recognition is an effective way for reservoirs prediction
