In the case that the signal-to-noise ratio and the number of times of superimposition are both rather low, the routine processing is not effective, and frequency division processing may be used. Seismic refleceted wave periods of different frequency bands show remarkable differences, and hence the separate automatic residkual statics and cross correlation statics could accurately evaluate residual time difference, the teverse Qcompensation and the superimposition of edaptive oblique plane elements could perform frequency compensation and phase compensation in a better way, increase the number of times of superimposition and raise the processing quality. On the basis of the above-described processing, the seismic reflection energies of various frequency bands are added to each other to obtain the final superimposition profile and raise the processing effect.
