| 摘 要： | 地震数据道内插是偏移处理前的重要工作。本文在理论模型研究的基础上 ,简要分析了在 f- x域和 f- k域二维道内插存在的问题 ,根据二维 f- k谱外推方法 ,给出了在 f- k域实现三维波场道内插的基本公式。所用算法已编制了相应的串行模块和基于 HPF(High Perform ance Fortran)高性能语言的并行程序 ,可在自行开发的微机群上得以实现。理论模型和实际资料处理结果表明 ,本文方法可以实现三维波场的精细、快速内插。

| Abstract: | Seismic trace interpolation is an important work before migration.On the basis of theoretical study of models,the paper briefly analyzed the problems existed in 2-D interpolation in f-x and f-k domain and gave basic formula of 3-D seismic trace interpolation in f-k domain based on extrapolation of 2-D f-k spectrum.The used algorithm has been programmed by using corresponding serial modular and parallel routine based on high-performance language HPF.The program has been succeeded in realizing on PC group.The processing results of synthetic model and real data showed that the method can do 3-D wave-field interpolation finely and rapidly. |
