A Research on Mountain Seismic Data Processing Methods

In viewing of the strong topographic irregularity and the low signal-to -noise ratio of seismic data in mountain area in Yiyang basin,ex periments were carried out on static correction,prestack noise elimination,DMO,iteration and stacking and F-X domain signal enhancement.A set of processing flow diagrams suitable for mountain seismic processing was established.Real data verified that the signal-to -noise ratio of the pro-cessed seismic section increased by a big margin and the wave sets had clear hierarch and distinct features.
