Abstract：After normal moveout correction，the seismic reflection waves of adjacent traces in one CDP trace gather which was formed according to ray principle have similar waveforms and nearly equal arrival times. Without such characteristics，these seismic waves may be considered as noise waves，or the reflection waves that interfere with noises. According to this principle，a finite small time window can be taken to delete seismic noises and then to produce a noise-deleted tracing fitting section. It has been shown that noise-deleted tracing fitting section exhibits better resolution，higher S/N ratio and much improved continuity of seismic event than horizontally stacked section, polynomial fitting section and noise-deleted fitting sect1on.
