Abstract:Seismic logging wavelet is transformed into seismic wavelet, which is used to obtain dephasing filtering operator in frequency domain.This dephasing filtering operator is then used to perform zero一phase filtering of seismic data so as to get zero一p:t}ase section, Compared with conventional seismic sections,the zero一phase section has higher resolution, and the time picks of its stro ng legs correlate better with the corresponding reflection coefficients.
