摘要
在地震数据高信噪比、高分辨率和高保真度处理中,高信噪比是高分辨率和高保真度的前提。因此,选择有效的去噪方法是提高资料品质的关键。以松南东岭地区三维地震资料处理为基础,主要采用CGGVeritas5000处理软件中的FDNAT模块分频压制高能噪音,TDNFK模块压制低频面波,RAMUR模块压制多次折射波。通过去噪处理,资料信噪比有了很大改善。
During 'Three Highs'(high SNR, high resolution and high fidelity)processing of seismic data, high SNR(signal to noise ratio)is the prerequisite. Therefore,an effective method of de-noising is the key to increase data quality. Based on 3D seismic-data processing of Dongling area, this paper adopts FDNET module of CGGVeritas5000 software to suppress high-energynoise with dividing frequency, TDNFK module for low-frequency surface wave and RAMUR module for multiple refraction wave, respectively. This de-noising processing improves SNR magnificently.
