Abstract: Quantitative evaluation for carbonate reservoir can improve the accuracy and correction of reservoir evaluation. The factors that are used in quantitatively evaluating carbonate reservoir are too more, so it is quite important to know how to use these factors and their relationships. Research finds the factors have some typical hierarchic properties, and therefore hierarchic analysis method can be used as important quantitative indexes. Combined with fuzzy comprehensive evaluation, it can be used to evaluate reservoir quantitatively. A quantitative evaluation example for every members of the Jia-2 member in the Jialing River formation in Moxi area which is situated in central Sichuan suggests that the calculating result is accordance with the actual result, in another word, hierarchic analysis method is effective.

Key words: hierarchic analysis, carbonate reservoir, quantitative evaluation, fuzzy evaluation, Jia-2 member of Moxi area
