Abstract：As an inversion method,full waveform inversion can theoretically provide higher imaging accuracy, full waveform inversion has become a hot topic in the field of seismic exploration. However, one of the major problems it faces is the huge amount of computational load, especially for full waveform inversion of 3D elastic media. In view of this problem, a parallel implementing strategy for full waveform inversion of 3D elastic waves based on the domain decomposition technique is developed in this paper. Firstly, the theory of full waveform inversion is briefly introduced, and then the main problems in the parallel implementation of domain decomposition are analyzed in detail, followed by corresponding solutions. Finally, the correctness and effectiveness of the algorithm are illustrated by a simple transmission model.
