Two typical theoretical geological models with four horizontal interfaces and rugged topography are calculated and analysed in this paper.The results further demonstrate that the application of conventional static and NMOcorrection of level datum plane to reflection multiple stacking under the condition of complex topography fails to achieve the aim of ideal multiple stacking and,what is more, gives rise to the problem of producing distortion of phase axis and character of false events. It is proved that the method of static and NMOcorrection and stacking at slip reference plane using reflection multiple stacking technique in areas with complex topography is effective, practical and operable.
