【Abstract】 To remove the bad influence of residual normal moveout upon seismic data res-olution, 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 coef-ficients criterion. Eliminate dynamic correction stretch by making filtering interpolation with the use of Butterworth filter, so that we remove the bad influence of residual nor-mal moveout, recover the original resolution of seismic data,and attenuate the nois-es which have resulted from stacking processing. Teoretical and real results show that the method brings satisfactory effect.更多还原
