Abstract：Currently more used minimum phase deconvolution method supposed that the wavelet is minimum phase, which is unsui table for real seismic wavelet with non-minimum phase, limited the improvement of resolution in seismic data processing. Even though the real seismic wavelet is minimum phase, using minimum phase deconvolution method can also introduce more noise with high frequency, reducing S/N ratio. The method for series deconvolution by resolution into factors presented by this paperavoids the supposition that the wavelet is minimum phase. The possible factors of wavelet are obtained through resolution into factors by self-correlation, then the operat or of deconvolution corresponding to each resolved factor of wavelet can be calculated separately and selection is carried out according to maximum or minimum phases, finally the try and judgment for each factor series resulted in deconvolution with non-minimum phase wavelet. The application of theoretical and real data showed that the method for series deconvolution by resolution into factors can significantly improve the resolution and S/N ratio in some degree, the effect is prior to currently-used minimum phase deconv olution method even if the wavelet is minimum phase.
