摘要： This disclosure relates to the technical field of exploration geophysics, in particular to a method, a device, and a computer device for decoupling anisotropic elastic wave. The method includes: determining a set of Thomsen parameters included in an anisotropic model based on a received to-be-decomposed wave field decomposition request; transforming the set of Thomsen parameters to obtain a set of initial elastic parameters; performing S-wave and P-wave velocities separation processing for the set of initial elastic parameters to obtain a set of target P-wave elastic parameters and a set of target S-wave elastic parameters; and substituting those into the anisotropic model to process the to-be-decomposed wave field and obtain a target P-wave matrix and a target S-wave matrix. The process of decomposing S-wave and P-wave fields is simplified and the calculation cost is reduced according to the embodiments of this disclosure.
