地震资料“高信噪比、高分辨率、高保真度”三高要求中,信噪比是基础,提高信噪比是地震资料处理的首要任务。本文在分析埕岛东坡干扰波的基础上,综合评述了常用的几种去噪技术,包括区域F-X域相干噪音衰减面波技术、区域异常噪音衰减技术、线性噪音衰减技术、多次波压制技术等。地震资料的去噪问题需要根据噪音的具体特征,采用合理、有针对性的去噪方法和技术。
Seismic data “high signal to noise ratio, high resolution, high fidelity ” three high requirements, the signal to noise ratio is the basis, to improve the signal to noise ratio is the primary task of seismic data processing. Based on the analysis of the interference wave in the east slope of Chengdao Island, several commonly used denoising techniques are reviewed, including the regional FX domain coherent noise attenuation surface wave technology, the regional abnormal noise attenuation technology, the linear noise attenuation technology, the multiple suppression Technology and so on. The seismic data de-noising needs to be based on the specific characteristics of the noise, using reasonable and targeted denoising methods and techniques.
