The present application provides a shale oil reservoir compressibility determination method, device and compressibility determination system, the determination method includes: obtaining compressibility evaluation parameters of the shale oil reservoir, and the compressibility evaluation parameters are: The data corresponding to the influencing factors of the compressibility of the shale oil reservoir; the compressibility evaluation parameters are analyzed by the dimensionality reduction method, and the independent evaluation parameters are obtained; the compressibility index is calculated according to the independent evaluation parameters; according to the compressibility index Determining the compressibility of shale oil reservoirs. The above determination method adopts the dimension reduction method to analyze the above compressibility evaluation parameters to obtain independent evaluation parameters, so as to facilitate the calculation of the compressibility index, so as to determine the compressibility of shale oil reservoirs according to the compressibility index. The determination method of reservoir compressibility and clay mineral content and other experimental methods are determined by brittleness index, and various compressibility evaluation parameters that affect the compressibility of shale oil reservoirs are comprehensively considered. The analysis and evaluation are more comprehensive and improve the Accuracy of compressibility evaluation. |
