Light hydrocarbon compensation correction method for shale oil content parameter S1

The invention relates to the field of oil-gas exploration, and discloses a shale oil content parameter S1 light hydrocarbon compensation correction method, which comprises the following steps: respectively carrying out online pyrolysis on a simulated shale sample and an underground shale sample with corresponding maturity in a natural evolution profile; performing quantitative analysis of hydrocarbon components on pyrolysis products of the simulated mud shale sample and the underground mud shale sample; respectively acquiring the proportions of light hydrocarbons in total hydrocarbons of the simulated shale sample and the underground shale sample from quantitative analysis results; and performing light hydrocarbon compensation correction on the oil content parameter S1 of the underground mud shale sample according to a comparison result of the proportions of light hydrocarbons in the total hydrocarbons of the simulated mud shale sample and the underground mud shale sample. Therefore, the accuracy of recoverin
