摘　　要：通过塔中沙漠地震资料特征的分析 ,提出了分偏移距地表一致性剩余静校正、叠前多域去噪等技术 ,总结出一套适合于沙漠地区低信噪比资料的处理方法 ,经实际地震资料处理后 。Based on an analysis of the seismic data of Tazhong desert, the authors put forward such techniques as residual static correction of separate migration consistency from the surface and multirange denoisization before stack. The practical seismic data processing has remarkably improved the signal-to-noise ratios of medium and deep layers. This paper has summed up a set of processing techniques of low signal-to-noise ratio suitable for desert areas.
