The invention provides a quantitative evaluation method for determining a longitudinal dessert section of carbonate-rich shale oil, which comprises the following steps of: 1, carding shale oil dessert control elements, and establishing a shale oil comprehensive evaluation parameter system; 2, preferably selecting parameters capable of being quantitatively evaluated from four shale oil property parameters including oiliness, storage property, mobility and compressibility; 3, determining a parameter grading evaluation standard and a weight capable of being quantitatively evaluated; and step 4, performing small-layer fine division and comparison on the research area, calculating a comprehensive evaluation index SI of each small-layer shale oil dessert section according to the set optimal parameter weight and grading standard, and determining the shale oil longitudinal dominant dessert section. According to the quantitative evaluation method for determining the longitudinal dessert section of the carbonate-rich s
