2D Seismic Data Processing in Yichuan Basin

A processing procedure is designed, which consist of crooked line processing, relative refraction statics correction, automatic restraining of large implitudc, dip filtering, predictive deconvolution, automatic residual static correction, velocity analysis, phase correction, restraining noise in F-X domain etc, to deal with the charactcristies of acute topography inequality, violent varying in low velocity region, low signal -to-noise ratio of the original record, serious crooked line and the phase difference of the records between two sources (dynamitc source and vibroseis)in the area. The result show that the seismic section was improved obviously.
