英文摘要	An interpolation method is presented in this paper for interpolation of three-dimensional seismic data by means of Laplacian algorithm of smooth restriction. Considering the idea of discrete smooth interpolation (DSI) studied by Mallet, we use precondition conjugate gradient method to compute the grid values directly and avoid finding the function fitting interpolating equation. In order to compute the converse of Laplacian algorithm rapidly, the theory of helical spectral factorization method is applied. In the helical coordinates, the matrix of Laplacian algorithm has the Topelitz structure, and its rapid converse can be got using spectral factorization. Based on the two dimensional DSI, one flow is presented in this paper to do DSI along the time slice by use of conjugate gradient method combined with NMO. The good results were achieved after the processing of model data and real three-dimensional data using this method.
