Rock thermophysical parameter prediction method based on stratum factors

The invention discloses a rock thermophysical parameter prediction method based on stratum factors. The rock thermophysical parameter prediction method comprises the following steps that collecting rocks with different lithology in a research area and preparing a sample; measuring the density, porosity, longitudinal wave velocity, transverse wave velocity and resistivity of the sample; under the conditions of normal temperature, normal pressure, temperature T and pressure P, respectively testing heat conductivity, and calculating a thermal diffusion coefficient and specific heat capacity; inputting the density, the porosity, the longitudinal wave speed, the transverse wave speed, the resistivity, the thermal conductivity, the thermal diffusion coefficient and the specific heat capacity obtained at the normal temperature and the normal pressure into a BP neural network model for training; correcting rock thermophysical parameters under the conditions of the temperature T and the pressure P by utilizing normal
