Doing the further research on the division frequency stack on the foundation of study of predecessor, at first the residual moveout correction is done to the seismic record, make the phase axle regularity, doing foundation for the same phase stack ; then carried on division scale processing by wavelet transform ; spectrum whitening is done to each scale, the high and low frequency band need to do prolongs, the middle frequency bands only increase the value of the frequency spectrum ; several kinds of methods that estimate the value of signal - noise ratio has been studied further, and summarize their advantage and disadvantage as well as the scope of application ; the seismic record after spectrum whitening is stacked by weighting with the value of the signal - noise ratio ; then estimate the value of signal - noise ratio which is each scale section after stacking, the scale that the signal - noise ratio is big is assigned big weighting, otherwise, the scale that signal - noise ratio value is small is assigned small weight ing, and carried on weighted reconstruct to each scale section
本文在前人研究的基礎上，在分頻疊加方面做了進一步的研究。首先對地震記錄進行剩餘時差校正，校齊同相軸，為同相疊加做好基礎工作；然後對地震記錄用小波變換的方法進行分尺度處理；對各個尺度分別做譜白化，對于高、低頻段需要做頻帶延拓，中間頻段僅提升頻譜值；對于幾種信噪比定量估計的方法進行了深入的研究，並且總結了它們的優缺點以及適用范圍；對譜白化后的地震記錄用信噪比估計值作為加權系數進行加權疊加；對于各尺度的疊加剖面也進行信噪比估計，對于信噪比大的尺度給予大的加權系數，反之，信噪比值小的尺度給予小的加權系數，對各尺度疊加剖面進行加權重構。 -
This can increase efficiently the signal - noise ratio of seismic record, under the general situation, the signal - noise ratio of big scale is small, because low frequency surface wave in big scale is more serious, the correlate of signal is smaller, so weighting stack can press efficiently low frequency surface wave, comparative promote the percentage of the effectual signal in constructing the signal
這樣可以有效地提高重構后地震剖面的信噪比，一般情況下，大尺度的信噪比都較低，因為大尺度內的低頻面波比較嚴重，信號相關性較小，這樣做加權可以有效地壓制低頻面波，相對地提升有效信號在重構信號中的百分比。 -
Consequently, there are much more noises in seismic acquisition, and static correction is difficult, and the seismic record is lower resolution and lower signal - to - noise, seismic data is far from the need of seismic interpretation
受其影響，在地震勘探的採集過程中產生了大量的干擾波，使得地震勘探靜校正量大，干擾嚴重，造成地震資料信噪比和解析度低，遠遠不能滿足地震解釋的需要。 -
