The invention provides a carbonate rock bursting pressure calculation method, system and equipment and a medium. The carbonate rock bursting pressure calculation method comprises the steps that the variable quantity of each physical property parameter and mechanical parameter of a rock core compared with the non-soaked rock core is obtained, and a relational expression that the variable quantity of each parameter changes along with the soaking duration is obtained through index fitting; drawing a cross plot according to the static Poisson's ratio and the static Young's modulus and the dynamic Poisson's ratio and the dynamic Young's modulus, and performing linear fitting to obtain a relational expression of dynamic and static conversion; for the target well, dynamic parameters obtained through logging calculation are converted into static parameters, and then physical property parameters and mechanical parameters are corrected to be in the non-soaked state according to the soaked time; and constructing a fracture pressure calculation model, introducing the corrected physical property parameters and mechanical parameters, and calculating the fracture pressure of the carbonate rock. According to the method, drilling fluid invasion dynamic conditions are considered, and the bursting pressure calculation is more accurate.
