Abstract：In complex piedmont high steep structural regions, stack velocities are imaging velocities used to obtain better imaging results in seismic data processing, which can't reflect the velocity-variant law of underground horizons because of impact of deformation of plastic salt formation and over-thrusting formation. Therefore, using stack velocity data and ordinary velocity-field-building method are difficult to correctly determine the structures. In view of the feature of complex high steep structural region with many years' study of velocity and field-building experiments, the paper presented ve- locity-studied idea and field-building method suitable for complex high steep structural region-interval-velocity-replaced field-building method for complex high steep area. The method was used to determine structural belt and achieved good results, provided a reliable structural map for oil/gas exploration in East Qiulitage structural belt.
