摘要

在每次迭代中,利用反向时间迁移结果而不是最小二乘反向时间迁移结果,可以提高交叉相关反射波形反演的计算效率。然而,交叉相关反射波形反演的反演效果需要优化,因为反演结果可能并不理想。传统的交叉相关算子往往会产生干扰值,从而影响时移估计的精度。此外,通过动态图像扭曲获得的时移可能会出现尖峰干扰,从而难以确定准确的时移值。这些挑战会导致反演过程收敛到局部最小值,从而影响反演结果的质量。为了解决这些局限性,本文提出了一种基于动态图像扭曲的新方法,即交叉相关反射波形反演。所提出的方法整合了动态图像扭曲衍生的加权规范,在整个反演过程中有效地调节时移值。通过使用简单的两层模型和重新采样的 Sigsbee 2A 模型进行模拟,验证了基于动态图像扭曲法的交叉相关反射波形反演的有效性。通过对比分析,评估了基于动态图像扭曲的交叉相关反射波形反演在减轻交叉相关干扰方面的性能,证明了它与传统的交叉相关反射波形反演方法相比具有更强的能力。

Cross‐correlation reflection waveform inversion based on a weighted norm of the time‐shift obtained by dynamic image warping
The computational efficiency of cross‐correlation reflection waveform inversion can be improved by utilizing the outcomes of reverse time migration instead of the least‐squares reverse time migration results in each iteration. However, the inversion effect of cross‐correlation reflection waveform inversion needs to be optimized as the inversion results may not be optimal. The conventional cross‐correlation operator tends to produce interference values that can compromise the precision of time‐shift estimations. Moreover, the time shift obtained through dynamic image warping can exhibit spiky disturbances, making it difficult to determine accurate time‐shift values. These challenges can cause the inversion process to converge to a local minimum, thereby affecting the quality of the inversion results. To address these limitations, this paper proposes a new approach called cross‐correlation reflection waveform inversion based on dynamic image warping. The proposed method integrates a weighted norm derived from dynamic image warping to effectively regulate the time‐shift values throughout the inversion process. The effectiveness of the proposed cross‐correlation reflection waveform inversion based on the dynamic image warping method is validated through simulations using a simple two‐layer model and a resampled Sigsbee 2A model. A comparative analysis is performed to evaluate the performance of cross‐correlation reflection waveform inversion based on dynamic image warping in mitigating cross‐correlation interference, demonstrating its superior capability compared to the conventional cross‐correlation reflection waveform inversion method.

期刊介绍: Geophysical Prospecting publishes the best in primary research on the science of geophysics as it applies to the exploration, evaluation and extraction of earth resources. Drawing heavily on contributions from researchers in the oil and mineral exploration industries, the journal has a very practical slant. Although the journal provides a valuable forum for communication among workers in these fields, it is also ideally suited to researchers in academic geophysics.
