摘　　要：本文对地震记录受地表因素影响产生的相位畸变问题进行了研究,提出了地表一致性常相位补偿理论和方法.该方法假设受地表因素的影响地震反射波相位在不同频率上只差一个常数相位,因此,该方法是地表一致性相位校正的一种近似方法。该方法的提出弥补了常规处理的不足,丰富了地表一致性相位校正理论和方法。人工合成记录和实际资料的处理结果表明该方法具有一定的实用价值和应用前景.This paper studies the phase distortion problem that arises from the near surface faetor affecting onseismogram. We propose the theary and method for the near surface consistant constant phase compensation.Themethod is an approximate approch of the near surface consistent phase correction assumming that seismic reflec-tion wave phase is constant difference on different frequence. This method overcomes the defeat of conventionalprocessing, and abundents the theories and methods of the near surface consistent phase corrections. Syntheticseismogram experiment and real data processing show that the method can be applicated for practical purpase.
