Abstract：The static corrections in complex area have been always the "bottleneck" in seismic exploration. The refraction static correction based on refraction theory is not suitable for the complex area characterized by severely relief surface and rapid changed velocity both laterally and vertically in neither the hypothetic precondition nor the practical application effects. For that reason, the paper recommended the static correlations by first breaks tomographic inversion,and used the method for field acquisition and indoor processing.By using travel times of first breaks on seismic records to compute the distribution of velocities in the media, that improved the precision of near surface model building and achieved good effects in practical production
