The invention discloses a reservoir classification method and device. The reservoir classification method comprises the following steps: acquiring a feature parameter set of different depth points of a plurality of reservoir sections of a to-be-classified well section; the characteristic parameter set comprises a logging characteristic parameter set and a core characteristic parameter set; analyzing the feature parameter set of the plurality of depth points through a principal component analysis method so as to extract at least one principal component parameter of each depth point; performing clustering analysis on the principal component parameters of the plurality of depth points, and dividing the plurality of depth points into a plurality of types; and classifying the reservoir types of the to-be-classified well sections according to the various types of logging parameters. According to the method, fine classification of the complex unconventional reservoir can be realized, and reference is provided for co
