摘　　要：针对宜阳盆地山地地表变化大、地震资料信噪比低的特点,主要就静校正问题、叠前净化处理、目标速度分析、DMO技术、优化迭代叠加技术和F-X域信号增强处理进行试验分析,建立了一套适合山地地震资料处理特点的处理流程。实际资料证明,处理的地震剖面信噪比明显提高、波组层次清楚,特征明显。In viewing of the strong topographic irregularity and the low signal-to -noise ratio of seismic data in mountain area in Yiyang basin,ex periments were carried out on static correction,prestack noise elimination,DMO,iteration and stacking and F-X domain signal enhancement.A set of processing flow diagrams suitable for mountain seismic processing was established.Real data verified that the signal-to -noise ratio of the pro-cessed seismic section increased by a big margin and the wave sets had clear hierarch and distinct features.
