Abstract
In view of seismic data characteristics and current prob-lems in actual production, some specific practices on pres-tack noise suppression have been introduced in this paper.Through suppression of surface wave and acoustic wave, automatic identification and suppression of linear interference,suppression of single-frequency interference, elimination ofburst noise and suppression of random interference, the signal to noise ratio has been greatly improved, resulting in anenhanced accuracy of seismic data processing as a whole. Besides that, the paper also points out different methodsshould be used in different area to carry out specific processing. Only by doing so, noise suppression could be effectivelyrealized.
