At
the area with complex surface conditions, such as desert, mountainous area and
loess plateau, the datum static correction is inaccurate as a result of the
large topographic variations, the thick low-velocity layer and its rapid
variation of velocity in the horizontal direction, which has strict
requirements on the residual static correction during seismic data processing.
The result points out that the common surface location method and Satan
algorithm are better than Maximum stack-power method without the impact of
structural items, because the former two methods can improve the model traces
and estimate the large residual static moveout with better processing results.
