在无井多道区演方法的基础上，结合已知井的资料建立初始模型和提取子波，将多道反演的思路应用于宽带约束反演，提出了多道宽带约束反演的方法。该方法在实际资料上的应用是有效的，反演结果保持了宽带高分辨率的特点，多道宽带约束反演的残差剖面也明显优于单道宽带约束反演的残差剖面。
On the basis of no well multi-channel method of regional performance, combined with the well data to establish the initial model and extract the wavelet, the idea of multi-channel inversion is applied to the broadband constrained inversion and a multi-channel broadband constrained inversion method is proposed . The method is effective in actual data. The inversion results maintain the characteristics of wideband high resolution. The residual cross section of multi-channel constrained inversion is also significantly better than that of single-channel constrained broadband constrained inversion.
