Abstract:Conventianai residual static correction method is normally implemented in two steps: 1. extraction of time difference from reflection events and 2. application of statics separated from the time differences, J. A. Hileman (1968),M. T. Toner (1974),G. Saghy (1975),R. A. Wiggins and L. C. Morlay (1983)and others have proposed variety of residual static models,Now people not only treat static correction as a linear problem, but also take acount of the amplitude attenuation caused by surface anomolies. The paper introduces a completely different surface anamoly correction method: various spectra components are decomposed in frequency domain to derive a decanvolution operator of surface anomoly and then filter the seismic trace with this operator to compensate the amplitude attenuation of the reflections and partial time delay caused by surface anomoly,Thus, the application of automatic residual static correction method is expanded.
