Reservoir management element is a process of decision-making，which involves with complex relationship and many factors.The rationality of management evaluation method directly determines the management level and affects the development and promotion of management level.In the past，management evaluation was mainly based on the premise that management elements were independent，and the evaluation conclusion could not reflect the relationship between element sets and elements.Based on the principle of fuzzy evaluation，this paper describes the internal relationship of management elements， uses the fuzzy network analysis method， uses the triangular fuzzy number to construct the network super matrix，and calculates the weight of each element.Taking two reservoirs as examples，the results show that the management level of Reservoir 1 is level 3，and the management level of Reservoir 2 is level 2.The evaluation results are consistent with the actual management level of the reservoir.The reliability of the evaluation method is demonstrated，which provides a technical basis for improving the evaluation system of reservoir management and improving the management level in the future.
