Abstract: The GeoEast software and its advanced geophysical functions were adopted in the processing of marine seismic data from two-dimensional towing. Single-shot seismic data could be decoded and the geometry could be loaded quickly. Removing the surge noise and multiple wave is a difficult job in marine seismic data processing. It is effective in our practice to remove the surge noise by depressing anomalous amplitude. And according to the characters of the multiple reflection wave in this region, we selected SRME and Radon transformation to suppress multiples effectively.
