Abstract The signal/noise ratio weighted stack method by dividing frequency band is described in this paper. Weighted factors are given according to quantitatively-calculated signal/noise ratios. This method can effectively improve signal/noise ratios of stacked section without causing much damage to seismic resolution. Quite good effects have been made in real data processing.
