Abstract：To remove the bad influence of residual normal moveout upon seismic data resolution,we put forward a method which takes the following steps: •Derive the model trace from stacked seismic traces by doing forward and backward predictions. •Estimate residual normal moveout according to the maximum similarity coefficients criterion. •Eliminate dynamic correction stretch by making filtering interpolation with the use of Butterworth filter, so that we remove the bad influence of residual normal moveout,recover the original resolution of seismic data,and attenuate the noises which have resulted from stacking processing. Teoretical and real results show that the method brings satisfactory effect.
