According to the variance module and resolution after deconvolution, the ideal mixed phase wavelets may be extracted from the wavelet gatherings with the same amplitude spectrum and different phase spectrums finally. Therefore the target for raising the resolution of seismic records can be attained by the determinacy wavelet deconvolution. Through the wavelet extraction tests for theoretic synthetic records and actual seismic data and the processing of enhancing resolution of seismic data by use of the wavelets extracted, it was shown that such a method is correct and effective.
