Abstract: The lithologic property and pore space of buried carbonate reservoir are very complicated, the classification of reservoirs is strongly fuzzy, and the logging data are often fuzzy and multisoluble. Based on a comprehensive analysis of well logging, core observation and well testing data of a buried carbonate reservoir, a fuzzy clustering method used to classify reservoir and es-
tablish evaluation norm of burial reservoir is put forward, and a fuzzy pattern recognition method is used to evaluate a buried carbonate reservoir comprehensively. The successful applications of fuzzy evaluation method to the Block Su103 in western Liaohe depression and the structural belt Hexiwu in Langgu depression Huabei shows that the method is effect.

Key words: fuzzy mathematics, reservoir evaluation, buried hill
