地震子波在地震数据处理中扮演着至关重要的角色，传统的子波提取都是假设子波为最小相位的，但是实际数据中的子波却是混合相位的。为了能够得到一个较为准确、真实的地震子波，笔者采用高阶双谱进行子波重构，然后利用得到的地震子波对叠后数据进行子波整形处理。仿真实验和实际资料试算结果表明，高阶双谱提取的地震子波与实际情况吻合度更高，利用所提取的子波对叠后数据进行处理，可改善剖面的分辨率。

Seismic wavelet plays a vital role in seismic processing,the traditional wavelet extraction is based on the minimum phase wavelet in seismic data.However,the wavelet in the actual seismic data is of mixed phase.In order to obtain a more accurate wavelet,the authors used high?order bispectrum to reconstruct the seismic wavelet so as to get a more accurate wavelet,and then conducted wavelet shaping processing to improve the vertical resolution of the seismic by using the statistical wavelet. The feasibility of using high?order bispectrum to reconstruct the seismic wavelet was proved by the simulation experiment. Practice shows that the statistical wavelet has good application effect in wavelet shaping processing.
