摘　　要：山地地震资料的特点是静校正量大,地震资料的分辨率和信噪比较低,这直接影响了地震解释方案,导致构造成果可靠性下降,不利于油气勘探开发。因此,如何有效进行静校正和去噪处理,成为人们关注的焦点。文中总结了山地低信噪比地震资料处理的主要技术思路,采用多种静校正相结合的方法,解决静校正问题,同时运用多域去噪技术,有效压制了噪音,最大程度地挖掘原始资料的潜力,提升资料的信噪比。Mountain seismic data featured by great static correction directly affects seismic interpretation with a low resolution and signal-to-noise ratio,resulting in reducing reliability of tectonic effort and unfavoring gas/oil exploration and development.Therefore,implementing static correction and removing noise availably are focused by people.The paper concludes the primary techniques of mountain seismic data processing with a low signal-to-noise ratio and introduces the methods to solve static correction problems by the combination of multiple static correction.Simultaneously,noise is controlled effectively by the application of removing noise in multi-region.As a result,the potential of primary data is developed furthest so as to upgrade a signal-to-noise ratio of data.
