Method and system for evaluating compressibility of carbonate reservoir

The invention discloses a method for evaluating the compressibility of a carbonate reservoir, and the method comprises the steps: collecting a plurality of groups of compressibility evaluation data related to a current reservoir according to the geological data and logging data related to a to-be-evaluated reservoir, the compressibility evaluation data comprises reservoir burial depth, slurry leakage amount, minimum horizontal principal stress, porosity, permeability, natural fracture inclination angle and high-angle fracture number, and the inclination angle of the high-angle fracture is greater than or equal to a preset angle; the change condition of the multiple groups of compressibility evaluation data is observed, and the influence degree of each type of single-factor parameters in the compressibility evaluation data on the compressibility of the reservoir to be evaluated is analyzed, so that a corresponding compressibility score is calculated; and according to the compressibility score, calculating the
