在深入研究波阻抗反演技术的基础上，针对其单道计算的特点，提出了一种简单易行的多道反演方法。该方法具体的实现步骤是：①采用频域归一化滤波算子将中、低频分量相加，形成无井多道反演的初始模型；②采用常规最小平方法提取最小相位反子波，求出子波，然后转换成零相位子波；③对数据拟合差剖面进行信噪分离或做压制噪声处理。应用结果表明，本文方法明显优于单道反演方法。
Based on the deep research on the wave impedance inversion technique, a simple and easy multi-channel inversion method is proposed according to the characteristics of single-path calculation. The concrete steps of this method are as follows: (1) Adopt the frequency domain normalized filter operator to add the middle and low frequency components to form an initial model without multi-channel inversion; (2) Use the conventional least squares method to extract the minimum phase transversal wave, Find the wavelet, and then converted into zero-phase wavelet; ③ data-fitting differential profile for noise separation or noise suppression. The application results show that the proposed method is superior to single-channel inversion method.
