Abstract: Static correction is the key to seismic processing in areas with complex surface conditions.Static correction value can be separated into a long wavelength static cor-rection component and a short wavelength static correc-tion component according to spacial variation.Different components have different impacts on data.Based on analysis of the advantages and disadvantages and applica-tion conditions of various static correction methods,a static correction processing flow chart is established by using current available static correction technologies tosolve successively the long wavelength static correction component,large short wavelength static correction com-ponent and short wavelength static correction component.A method is also presented to solve the problem of cross line closure.
