Abstract:The alias, frequency dispersion and lateral resolution of migrated seismic section are analysed in detail in this paper. The detailed analysis leads to the conclusion: the alias on migrated section has nothing to do with migration methods, but mainly relates to the samplings of record and operator, and their resamples; frequency dispersion is concerned with the accuracies of migration equation and difference; and the lateral resolution is related to equation accuracy and sampling rate. The application of more accurate equation and more precise sampling to migration processing is not only conducive to correct positioning of seismic data, but also necessary for improving the lateral resolution.
