The invention belongs to the technical field of petroleum exploration geology, and relates to a quantitative method of reservoir microscopic components. The quantitative method comprises the followingsteps: I) acquiring shape characteristics and energy spectrum characteristics of target microscopic components; II) pretreating a reservoir rock sample; III) scanning the pretreated reservoir rock sample by a scanning electron microscope to obtain an interested area; IV) dividing the interested area into a plurality of micro areas by an image processing technology, acquiring all the microscopic components in the micro areas, and analyzing the shape characteristics and the energy spectrum characteristics of all the microscopic components in the micro areas; V) comparing the shape characteristics and the energy spectrum characteristics of all the microscopic components in the micro areas with the target microscopic components, determining the target microscopic components in the micro areas, and calculating the are
