任意相位子波的分形反褶积方法

通过假设反射系数具有分形特性，并对预测误差滤波器进行修改，即可推导出任意相位的地震子波的反滤波方程，建立未知地震子波情况下求解反滤波因子和地震子波的迭代算法，该方法可以克服传统反褶积方法中假设反射系数为白噪声所带来的问题，能够明显提高剖面目的层段的分辨率，并具有一定的抗干扰能力。

Fractal deconvolution of any-phase wavelets

By presuming that reflectivity has fractal characteristic, and revising predictive error filter, we can deduce the antifiltering equation suitable to any-phase seismic wavelets, and construct an iteration algorithm for estimating the antifiltering oper-ator and wavelets without known seismic wavelet. The method helps people remove the problem in usual deconvolutions which results from a presumption that reflec-tivity is white noise. It favours obvious improvement of objective interval resolution of a seismic section, and has certain ability of noise resistance.
