在海上地震勘探中我们最常见的干扰波就是多次波。多次波的存在，严重地干扰了地震记录，妨碍我们对有效波的辨认。在剖面上存在较强的多次波时，如果在解释中不能正确地把多次波识别出来，就会造成错误的地质解释。所以，在海洋地震资料的处理中，多次波的衰减是极为重要的一个环节，对于中、深层海洋地震资料，本文采用如下方法压制多次波，先进行SRME方法去除长周期多次波能量，再应用tau-p域内预测反褶积去除占大部分的短周期多次波，最后用高精度Rado变换去除剩余的多次波，实际资料结果表明，该方法有不错的效果。

In the offshore seismic exploration, interference wave is the most common multiples wave. The existence of multiple waves seriously interfere with the seismic record, prevent us identify effective waves. when there is a strong multiple wave in the section, if the multiple wave can not be correctly identified in interpretation, the wrong geological interpretation will caused. Therefore, in dealing with marine seismic data, the attenuation of multiple wave is an extremely important aspect. For the middle and deep marine seismic data, this paper uses the following method for multiple wave attenuation, firstly performing SRME to remove the long-period multiple wave energy, then applying the tau-p domain predictive deconvolution to remove most of the short-period multiple wave,finally using high-precision Rado transform to remove the remaining multiples wave. The actual data results show that the method has a good effect.
