摘　　要：主要叙述了叠后地震记录分频去噪方法原理。该方法可对叠后各时间场道集记录进行分频谱白化与一致性校正迭加,消除由于地表激发,接收不一致,倾角及表层因素引起的剩余时差和噪音对记录的影响,从而提高地震记录的信噪比和分辨率。通过对实际资料处理,应用效果明显。This paper introduces a spectrum sharing noise elimination method of stacked seismic data, which can stack time domain trace with spectrum sharing whiten and consistent correction stack, which can eliminate the residual effect and noise by trace of surface explosion, receiving different, inclined angle and surface so on, and thus improves the resolution and signaltonoise ratio of seismic data. Processing result of real seismic data idicated that this technique was useful.
