基于ATV正则化与初始模型约束的波阻抗反演

Impedance Inversion via ATV Regularization and Initial Model Constraint

提出了一种基于各向异性全变分正则化和初始模型约束的波阻抗反演方法.为了综合利用地震数据的时空信息,提高反演结果的横向连续性,采用多道同时反演.实验结果表明,即使在强噪声干扰的情况下,利用该方法仍然能得到较好的反演结果,且反演误差较小.

An impedance inversion method via the anisotropic total variation regularization and the initial model constraint is presented.In order to make use of the spatiotemporal information of the seismic data and improve the lateral continuity of the inversion results,multi -trace inversion is used in this method.The experimental results show that even in the case of strong noise interference,this method can achieve good inversion results with small errors.
