WTBased 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 model data are clear and accurate. This demonstrates the reliability of the migration system. The isotropic migration of the data of anisotropic models shows that there are considerable errors on traditional migration sections where the positions of geological bodies are inconsistent with those in the real models.
