Low S/N Data Processing Technique in Zone of Desert in Yanqi

The seismic sections obtained from the lowsignal-noise ratio data in the zone of desert in Yanqiwith conventional processing techniques are not suitablefor geologic interpretation. We sucessfully solved theproblem of static correction by applying the softwarepackage of refractive interactive static correction technique.High signal - noise ratio sections that can be used forgeologic interpretation are obtained by using the lineardynamic correction technique and combining with F-Kfiltering, surface-consistent processing, highly accuratestacking and cornmon -source - point gather DMO.
