基于高阶双谱的子波整形方法
A method of wavelet shaping based on the high-order bispectrum
摘要
Abstract
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.关键词
