Abstract: In conglomerate reservoir,the lithology is complex and its heterogeneity is strong,which results in great differences of the utilization of reserves during water-flooding and so on. To solve these problems,based on the geological and development features of the conglomerate reservoir,the water-flooding development potential evaluation indicators system was set up considering heterogeneity,remaining reserve and flowing capacity of fluid. Then,on account of the characteristics of development performance in the actual oilfield,by taking the areal unit as the study object,development potential of different units can be classified in an unsupervised way through fuzzy C mean clustering method,which helps set up a subjective and reasonable evaluation method. This method was used to evaluate the development potential of BH oilfield in Xinjiang,and the results are consistent with the characteristics of the geological and development condition distributed regionally in BH oilfield,it is useful for implementing different adjustments in different regions. Furthermore,combined with different features of different potential regions,the corresponding development adjustment advice can be proposed.

Key words: conglomerate reservoir, water-flooding development, development potential, multi-factor evaluation, fuzzy clustering method
