| 摘 要： | 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

| Abstract: | The singular value decomposition (SVD) technology is a very effective method to eliminate the noise in a simple structure, especially that on the horizontal layer. But for the complex structure, it is not satisfactory . So in this paper, the authors proposed a new technology to solve this problem. It combines the automatic event search with the SVD technology. In general, SVD uses the whole profile data to compute. Now, the new technology is to compute window data near every sample. Also, it rotates the window data in order to keep horizontal direction of event. In the end of the paper, the example shows the new technology has a very good result for complex structure. |
