Based on the results of reservoir prediction by calculating the seismic attribute of maximum amplitude, using the trend constraint of the thickness of drilled sand body and combining the correction with the palaeogeomorphology, it is shown that the palaeogeomorphological framework consisted of valleys and swales that were separated from two arches during Paleogene Shahejie-2 sedimentation in Oilfield A. It is believed that the potential reservoirs are distributed in the palaeogeomorphologically low-lying areas in the northeast and especially the southwest. These methods of this reservoir prediction have been proved effective by drilling results of five designed wel s and helpful to the future development and implementation.
