低信噪比资料处理,特别是柴达木盆地低信噪比资料处理一直是处理工作的难点。从柴达木盆地东西部地区两种典型低信噪比野外单炮记录中的干扰波分析入手,对FOCUS系统中主要去噪模块进行分析研究,处理重点放在叠前叠后静校正和干扰压制两方面,总结出一套FOCUS系统在低信噪比资料处理中的去噪方法。 Low signal-to-noise ratio data processing, especially low signal-to-noise ratio data processing in the Qaidam basin, has always been a difficult task. Beginning with the analysis of two typical low S / N ratio single shot records in the eastern and western Qaidam basins, the main denoising modules in the FOCUS system are analyzed and studied, with the emphasis on post-stack post-stack static correction and interference Suppression of two aspects, summed up a set of FOCUS system in the low signal to noise ratio data processing denoising method.
