Zusammenfassung:The invention relates to a shale oil productivity evaluation method based on sensitive parameter superposition. The method comprises the following steps of logging a shale finished well to obtain a plurality of logging curves, and calculating the shale porosity, the total organic carbon content and the brittleness index; carrying out shale oil comprehensive quality evaluation to obtain a comprehensive evaluation index curve; and obtaining a productivity evaluation parameter curve by utilizing the superposition area after the brittleness index curve and the porosity curve are calculated and thebrittleness index curve and the total organic carbon content curve are reversely scaled, and evaluating the shale oil productivity through the productivity evaluation parameter curve in combination with oil testing data. According to the method, the reliability and practicability of comprehensive productivity evaluation can be improved, the perforation fracturing cost is reduced, and the single-well yield is improved. 本发
