Abstract

AbstractBased on the finite element method and the interface point method of shortest path ray tracing, reverse‐time migration for anisotropic elastic waves is carried out. The migrated sections of synthetic data are clear and accurate. This demonstrates the reliability of the migration system. Furthermore, we migrate anisotropic wave field data with isotropic migration method to find out the effect of ignoring anisotropy. The results show that there are considerable errors on isotropically migrated sections where the positions of geological bodies are inconsistent with those in the real models.
