Summary:The invention provides an in-situ combustion rock core parameter correction method and device, and the method comprises the steps: comparing a rock core natural gamma curve and a logging natural gamma curve of a rock core sample, and determining the buried depth of the rock core sample; analyzing to obtain reservoir microscopic characteristics and reservoir macroscopic characteristics of the rock core sample; judging a combustion zone where the rock core sample is located; drawing a porosity correction plate and a permeability correction plate of the rock core sample under the overburden pressure based on the parameter data after the abnormal values are removed, and obtaining corrected porosity data and corrected permeability data; drawing a first oil saturation correction chart based on the corrected porosity data and oil saturation data to obtain first corrected oil saturation data; and drawing a second oil saturation correction chart based on the nuclear magnetic resonance oil saturation data and the first
