Abstract：It should be done with reasonableness and or-dering for solving the issue of static corrections.The reasonableness means selection of suitablestatic corrections according to the practical situa-tion of near surface;the ordering means that itshould follow the order of long-wavelength beingfirst, then the mid-to-short wavelength as well asresidual static corrections to solve the issue of stat-is corrections. In order to solve the issue of staticcorrections in complex area.it should first build upnear-surface model;then, using model-constraintrefraction static correction to solve the issue oflong-wavelength static correction;the following isto use refraction residual static correction to solvethe issue of mid-to-short wavelength static correc-tion;and finally using frequency-shared static cor-rection to solve the issue of residual static correc-tion. The practical data processing showed that theset of approaches can achieve good results.
