Abstract: Static correction is an important link for seismic data processing. To make existed static correction tends to affecting stacking result of common depth point (CDP) and reality of structural feature on seismic profile, for low-amplitude structure, in particular, it is very easy to delete or counterfeit it due to the static corrections. In order to properly deal with the issue affecting seismic data quality in seismic data processing and in complex surface area, this study presents various methods for such static corrections, including advantages and shortcomings, prerequisites or conditions to use. In addition,examples are taken for how to apply these static correction methods so as to better solve the problems occurred in static corrections.

Key words: static correction, micro logging, refraction wave, analog annealing, tomographic image, inversion
