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.
