Rapid calculation method for all-anisotropic medium response of coaxial coil instrument

The invention discloses a coaxial coil instrument all-anisotropic medium response rapid calculation method, and relates to the technical field of exploration geophysics, and the method comprises the steps: s1, building a uniform all-anisotropic model; s2, coaxial coil instrument parameters are input, forward modeling is carried out, and coaxial responses of all the models in the step s1 are calculated; s3, obtaining an equivalent homogeneous isotropic model of the homogeneous full-anisotropy model; s4, establishing an equivalent coefficient library of the uniform all-anisotropic model; and s5, inputting the correlation coefficient of the application model into the equivalent coefficient library to obtain an equivalent isotropic model of the application model. According to the method, an equivalent isotropic model coefficient library of a homogeneous medium all-anisotropic model is established through a Gaussian-Newton inversion method and a Lagrange interpolation method; the anisotropic coefficient, the hole
