谱白化处理是提高地震勘探分辨能力的行之有效的方法。本文简述了谱白化处理的原理、实现过程及其参数的选择和使用。从实际处理中我们认识到该方法具有适应性广、可控性强、效果稳定的特点。文中给出的实例说明该方法既能提高分辨能力又不致将噪音放大得太厉害。最后还讨论了该方法的其它一些优点。

In seismic exploration, the spectral whitening is an effective measure for increasing the resolution. In this paper, the principle, the implementation procedure as well as the parameter selection and application of the spectral whitening were briefed to the point.We recognized by practice that this technique has the characteristics of wide adaptability, strong controllability as well as the stability in effects. Examples show that it could not only increase the resolution but it could also control the noise to some extent.
