This article provides a general overview of local wave decomposition (LWD) methods including empirical mode decomposition (EMD), ensemble EMD, complete ensemble EMD with adaptive noise, synchrosqueezed transform and variational mode decomposition applied to seismic interpretation, covering the theoretical background and applications. We explain how LWD methods can be reviewed as a special and stronger case of the classical seismic time–frequency methods and place emphasis on the interest of using such LWD methods in seismic instantaneous frequency extraction, seismic attenuation estimation and seismic resolution enhancement.

用于理解地震数据的局域波分解方法的最新进展：在地震解释中的应用

本文概述了局部波分解 (LWD) 方法，包括经验模式分解 (EMD)、集合 EMD、具有自适应噪声的完整集合 EMD、同步压缩变换和应用于地震解释的变分模式分解，涵盖了理论背景和应用。我们解释了 LWD 方法如何被视为经典地震时频方法的一个特殊和更强的案例，并强调在地震瞬时频率提取、地震衰减估计和地震分辨率增强中使用此类 LWD 方法的兴趣。
