Anisotropic rock physical modeling method and device

The invention provides an anisotropic rock physical modeling method and device. The method comprises the steps that the volume fraction of each mineral in a target mineral layer and the pore content of a target pore type are obtained, and the target mineral layer at least comprises one of the following components: a clastic mineral layer and a carbonate mineral layer; according to the volume fraction and the pore content of each mineral, respectively determining elastic stiffness matrixes of the detritus mineral layer and the carbonate mineral layer; determining a target elastic stiffness matrix according to the elastic stiffness matrix of the debris mineral layer and the elastic stiffness matrix of the carbonate mineral layer; determining anisotropic parameters of the core sample according to the target elastic stiffness matrix; and determining the target mineral content and the target pore content, and determining the elastic anisotropy of the rock core sample according to the anisotropy parameter, the targ
