description | The invention relates to the field of carbonate reservoir evaluation, in particular to a method and device for calculating the porosity of a carbonate reservoir. The method comprises the steps of carrying out a rock core calibration experiment, and determining the nonlinear characteristics of the porosity logging response of the carbonate reservoir; establishing a carbonate reservoir volume modeland a logging response equation, and establishing a nonlinear equation for the nonlinear characteristics; making the logging response equation simultaneous to form an equation set; iteratively solvingthe equation set to obtain the reservoir porosity. According to the method for calculating the porosity of the carbonate reservoir, nonlinear parameters are determined through the rock core calibration experiment, then the logging response nonlinear equation set is established, the calculation error of the porosity can be reduced, the data size of the porosity is increased, and the method is moresuitable for carbonate str |
