Abstract：Deconvolution has been usually adopted in the process of seismic data processing in order to improve resolution in reflection event of objective interval.However,the method has a difficulty in designing to highlight the frequency band information of major objective interval and give consideration to the useful information of other frequency band in the meantime.Although the filtering method in frequency domain can solve the time-variant filtering problem based on Fourier transform,the method may appear a false anomaly in conjunct part between windows. Faced with above-mentioned problems,the paper presented a method that seismic data are frequency-shared processing and reconstitution in wavelet domain.Under the precondition of improving the resolution in reflection event of objective interval and giving consider- anon to middle and lower frequency information at the same time,the processed seismic profiles have broadening frequency band and result a best reconstitution.Zhe paper also gave a concrete algorithm and real case analysis.Zhe results show that the method is theoretically correct and real application effect is success.
