///Prestack time migrated is based on high-precision migration velocity which can constrain geological structure model. Taking the sedimentary evolution of complex structures in the study area into account, this paper presents a reasonable geological structure model and the corresponding migration velocity field. According to Snell’s law, the prestack time migration processing to the 3D seismic data is conducted, obtaining a more reliable migration imaging, finding out five fault stratigraphic traps among which one is a stratigraphic trap, describing 3 fan bodies of Xiazijie Formation of the Permian. The effects of seismology and geology are gained.
