The invention discloses a method for correcting the safety management level of a refining enterprise, and belongs to the technical field of safety management evaluation of the refining enterprise. Themethod comprises the following steps: firstly, selecting a refining enterprise to correct an evaluation result to obtain an evaluation result N; obtaining the accident times of the refinery enterprise within 5 years and the death number, the serious injury number and the direct economic loss amount of money of each accident; calculating Y' through a grading module; calculating a correction factorof the enterprise safety management level evaluation result through a correction module; and finally calculating to obtain an evaluation result correction value M. Related information is input through the grading module, corresponding correction factors are obtained through calculation of the correction module, and the correction factors are applied to correct the safety level quantitative evaluation result of the enterprise. The influence of safety accidents on quantitative evaluation of the safety level of an enterprise is fully considered, calculation operation is easy and convenient, andan effective tool is provided for improving enterprise management.
