Prediction method and device for physical property parameters of low-permeability reservoir

The invention provides a method and device for predicting physical property parameters of low-permeability reservoirs, and the method comprises the steps: classifying the low-permeability reservoirs according to the characteristics of a hollow billet pressure curve of a cored well; defining a physical property quality index according to the micro-pore structure characteristics of the reservoir; establishing a physical property quality index reservoir classification standard according to the classification and the physical property quality index of the low-permeability reservoir; according to a physical property quality index reservoir classification standard, the porosity and the permeability are subjected to regression, and a reservoir porosity and permeability interpretation model is established in a classified mode; performing correlation analysis on the physical property quality index and the logging curve, then performing fitting, and establishing a physical property quality index interpretation model; a
