SVD去噪技术对构造简单地区,特别是地层近水平的情况下的地震剖面的去噪效果是十分明显的;对于构造复杂地区,该法往往失效。针对这个问题,作者提出了一种新的技术:它将同相轴的自动追踪与SVD去噪技术有机地结合起来;它将一般的SVD方法是针对整个剖面数据体来计算的,改变为针对每一样点的邻区,选择小时窗和小道窗的数据体来计算;它利用数据体的旋转方法,来实现同相轴始终保持水平方向;并采取了其他一系列的技术措施,使SVD方法在构造复杂地区取得了很好的去噪效果 The SVD denoising technique is very effective for the de-noising of seismic sections with simple structures, especially near strata; this method often fails in complex areas. In response to this problem, the authors propose a new technique: it combines the automatic tracking of S-axis with the SVD denoising technique; it general SVD method is calculated for the entire cross-sectional data body, to change for each The same point of the adjacent area, the choice of small windows and window windows data body to calculate; it uses the data body rotation method to achieve the horizontal direction of the axis; and to take a series of other technical measures to make the SVD method in the structure Complex areas have made a very good denoising effect
