摘要
In this paper,a method for seismic attenuation estimation is proposed.First operators of time frequency filtering are applied to a deconvolved seismic trace to obtain a reflectivity after attenuation.Then the attenuation estimation based on the reflectivity is performed.Completely different from the other methods,this method can obtain an attenuation estimation within a short time-window.This window can be shorter than the length of the time-window than the wavelength of the wavelet.
