Abstract: Based on the fuzzy matter-element analysis and approach degree concept, cluster analysis method of approach degree of fuzzy matter-element was presented to have established evaluation and classification standard of reservoirrs.The result of the case study agrees well with that of other methods and corresponded to the practice.This method may be referred.
