摘要
去噪技术在地震数据处理流程中占据着重要地位。随着地震勘探的发展,去噪技术也有了较快的发展。地球物理工作者在不断改进现有去噪方法的同时,也在不断探索新的去噪技术。从噪声分类入手,首先介绍了地震数据中的噪声,然后综合评述了近几年新发展的去噪技术,包括时频分析方法、反偏移方法、径向道变换法和基于支持向量机、形态学、独立成分分析的方法,最后对去噪技术的发展做了展望。
Noise elimination technology plays an important role in the workflow of seismic data processing.With the development of seismic exploration,denoising technology improves quickly.Geophysical workers not only make full use of the existing denoising methods,but also try to find better denoising techniques.In this paper,beginning with the classification of noises,we reviewed the advances in denoising technology in seismic data processing.Comments were made on the newly developed denoising techniques,including time-frequency analysis,demigration,radial trace transform,and methods that are based on support vector machine,morphology,and independent component analysis,respectively.The outlook for denoising technology was presented.
