Abstract
With the deepening of exploration of subtle reservoirs, such as complex fault block reservoir and lithology reservoir, amplitude-preserved non-stationary enhancing resolution technologies have been focused. Based on the traditional spectral modeling deconvolution, time-varying spectral modeling deconvolution in S transform domain is presented in this paper. In S transform domain, we obtain the timevarying amplitude of wavelet by the least squares fitting, low-pass filtering and multi-channel statistical weighting, adapting time-varying character of seismic records and adapting to the changes in SNR. Model test proved the correctness and effectiveness of the method.
