主　　题：Shale oil Storage mechanisms Storage characterization Hydrocarbon vapor adsorption 

摘      要：A new method is proposed to analyze the pore-scale mechanisms and characterization of light oil storage in shale nanopores,which is based on the Hydrocarbon Vapor Adsorption(HVA)and Pore Calculation Model(PCM).First,the basic principle of the HVA-PCM method is introduced,and the experimental/mathematical analysis processes are ***,the HVA-PCM method is applied to shale samples to analyze the mechanisms and characterization of light oil storage in shale *** results provide insights into the pore-scale oil storage mechanisms,oil storage structure,oil film thickness,oil distribution within different sized pores,and the oil storage ***,the advantages and limitations of the HVA-PCM method are discussed,and suggestions for further improvement are ***,the HVA-PCM method is a powerful tool for extracting quantitative information on the light oil storage in shale nanopores.
