针对陆上三维地震数据普遍存在的采集不均匀、空间采样率不足及振幅非一致性，不能满足FKK滤波技术前提条件的问题，对现有的FKK滤波配套技术方法进行认真分析，指出了其存在的不足，并给出空间假频门槛分析法，最后提出了三维地震数据规则化及能量一致性处理的FKK滤波配套处理方法，实际应用表明该配套处理方法是有效的。

In three-dimensional (3D)land seismic data acquisition,there are three common problems including non-uniform spatial acquisition,low space sampling rate and amplitude nonuniformity,which can not meet precondition of FKK filtering technology.Through analyzing the existing FKK filter technology,a spatial aliasing threshold analysis method was suggested on the basis of shortcomings of the technology.Finally,the 3D seismic data normalization and the energy consistent processing for the FKK filter technology were proposed.The practical application shows that the new method is effective.
