Abstract：Through making an approach to the principle of DMO integration in pre-NMO stage and on the basis of using the method that uses DMO for realization of 3-D data regularization presented by Canning（1996)and the method for azimuth moveout(AMO) of 3-D pre-stack seismic data presented by Biondi(1998),starting from azimuth moveout,the paper regularized the seismic data by using the processing flow that combines DMO and inverse DMO-1,obtaining surveying data having needed spedified azimuth under new and regular geometry.The method can be used for solving the problems such as interpolating pre-stack seismic data,regularizing the irregular surveying data in land seismic exploration and the correcting cable feathering in marine seismic exploration,etc,it also can transform the original seismic data to a new pre-stack seismic data set with specified geometry suitable for some special processing methods.The method has advantages of both simple principle and wide application.
