Abstract：Static correction is one of key issues that the seismic exploration faced with in complex near-sur-face,that constrained the quality of data processing to a considerable degree.On the basis of knowing near-surface velocity model,the paper studied the method of static corrections by using wave-equa-tion inversion,that is,summing static corrections up as the inversion of wave-equation boundary values (also called as inversion of unknown boundary values).In other words,the static corrections in near-surface can be realized by inversion of wave-equation boundary values.The paper give numeric solved method in view of the characters of inversion.The static corrections method is characterized by adaptation to complex surface relief and rapid near-surface velocity change and can fully consider the transmission,dispersion and reflection appeared when wavefield goes through the nearsurface,which made the continued wavefield have higher precision.The numeric modeling results proved the effectiveness of the method.
