The carbonate reservoir has a sound heterogeneity and low-permeability, which brings certain difficulties to the prediction of the remoulding of the reservoir. The effective comprehensive evaluation method of reservoir plays a significant role in the modification of the layers of well. Aiming at the characteristics of the reservoir geology, the paper builds up reservoir evaluation criteria based on the principles of geological evaluation and construct the membership functions and models of analytic hierarchy process, secondly, by the means of fuzzy analytic hierarchy process, the paper obtains the proportion of well logging, well testing, geology and geophysical prospecting to the importance of reservoir modification. Last, by the means of fuzzy comprehensive evaluation method, it gains the conclusion about whether the reservoir needs to be modification or not. The rebuilding results of reservoir shows that the above method can effectively resolve the consistency problem among various appraisal parameters, improve the accuracy of evaluation and the efficiency of the modification and reduce invalid production. This method has been successfully applied to the evaluation of low-permeability reservoirs in Tarim oilfield.
