An overview of the methods and techniques for seismic data noise attenuation
地震资料去噪方法、技术综合评述

For both prestack seismic gathers and stacked seismic data, noise attenuation is a very important part of seismic data processing. With the advancement of exploration techniques, the accumulated and developed software for noise attenuation are becoming more and more. It is valuable in theory and instructional in practice to sort different methods of noise attenuation and state their fundamentals, physical meanings, applied conditions and development futures. In this paper, we firstly divide the noise in seismic data according to different characteristics, and then overview some popular methods of noise attenuation in practice, including frequency filtering, frequency-wavenumber filtering, frequency-space filtering, the Radon transform, beamforming, methods of noise attenuation on the basis of wavelet decomposition and reconstruction, and so on. In the end, we also talk about the development trend of techniques for noise attenuation.
