Seismic data channel interpolation is an important task before offset processing. Based on the theoretical model, this paper briefly analyzes the existing problems of two-dimensional channel interpolation in f-x domain and f-k domain. According to the two-dimensional f-k spectrum extrapolation method, The basic formula of 3D wave field interpolation. The algorithm used has been compiled corresponding serial modules and parallel programs based on HPF (High Perform ance Fortran) high-performance language, which can be implemented on a self-developed microcomputer cluster. The theoretical model and actual data processing results show that this method can achieve fine and fast interpolation of 3D wavefields.
