The present disclosure relates to a boundary offset noise suppression method and device based on offset statistical sorting, including: performing offset data scanning on the acquired CMP gather, statistically obtaining each CMP number and its corresponding offset information, and forming a CMP gather offset information library; performing pre-stack migration processing on the CMP gather to obtain a migrated CRP gather; performing offset data scanning on the CRP gather, statistically obtaining each CRP number and its corresponding offset information, and forming a CRP gather offset information library; using the CRP gather offset information library to sort the CMP gather offset information library to obtain a CRP gather within the offset distribution range of the CMP gather.

In the past, the spatial interpolation method used for "arc drawing" during migration was not conducive to amplitude preservation processing and was prone to data distortion.
