Abstract：In view of the issue of static corrections in complex area that is difficult to be solved by conventional seismic static corrections, the paper selected joint application of three static corrections, primary field static correction by integrative model, refraction static correction by integrative optimization and reflection static correction by integrative optimization, to solve the problem, which avoids to abstract first breaks in single shot records and directly carries out computation of field near-surface information and of windows of refraction and reflection waves in seismic records. The practical data processing results showed that the method is effective method for rapidly solving long, mid and short wavelengths static corrections in complex area.
