【Abstract】 According to the performance characteristics of the underground gas storage, this paper obtains an integral optimum simulation model on the base of ensuring the smallest change of average stratum pressure in the reservoir by setting up a dynamic injecting-producing mathematical model for the underground storage, which makes objective function as following: the highest injecting velocity with the lowest power consumption of the compressor in summer, and the biggest production that the reservoir may obtained in winter, and makes corresponding restricted conditions. Applying the technic of system dynamic simulation and the method of multi-object optimization, and basing on the calculated results of each single-object optimization, the paper optimizes the system with multi-object and makes good use of the productive capability of the reservoir. It provides the theoretic foundation for the optimum performance management of factual underground gas storage.更多还原
