地震资料去噪处理的振幅保真性分析

Analysis of Amplitude Fidelity in Noise-removal Process of Seismic Data

对地震资料的各种去噪处理方法进行了详细探讨,在此基础上应用各种处理模块对理论地震模型和实际地震记录完成了去噪处理.通过处理前后地震记录的对比、频谱分析、信噪比估计、目的层振幅变化和相关性分析,提出地震资料去噪处理的保真性分析方法,验证了地震资料去噪处理模块的可行性.

Several methods of noise-removal in seismic data processing have been analyzed in detail, and on the basis of analyses, the noise-removal processing for both theoretical seismic models and real seismic data have been accomplished. The fidelity analysis method of noise-removal in seismic data processing has been proposed by contrasting the processed data and non-processed data for spectrum analyzing, signalto -noise ratio estimating, amplitude variation and pertinence analyzing of the target stratum. Finally, the feasibilitv of noise-removal modulo for seismic data processing has been verified,
