Abstract:The wavelet d(t) which is very similar to the wavelet of surface-seismic data can be obtained by ①extracting wavelet b(t) from theVSP data teat resemble the corresponding surface-seismic data;②making fast Fourier tiansforcn of b(t)to get B(t);③smoothing |B(f)|into |B(f)|;④filteritlg B(f)using filtering operator |B(f)|;⑤perform-ing inverse Fourier transform of the filtering result.Then a high-resolution zero phasehy(1) acquiring zero-phase shaping operator,(2)doing shape decon-volution of surface-seismic seismic data and (3)perfcr}rirg high S/N process-ing of the seismic data.
