Abstract: The initial signal/noise ratio of the 2-D seismic data acquired in the desert areas in Bayanhaote Basin are low,and the amount of static correction is large.In accordance with these datu characteristics,the following methods are applied in data processing: low-velocity layer and velocity-reducing layer modeling and interactive iterative statics, F-K velocity filtering,regional abnormal amplitude attenuation, surface-consistent compensation, manual interactive stacking velocity picking, shallow layer information protection, and random noise attenuation.Seismic sections with high signal/noise ratio are abtained with these methods.
