Abstract：

Gas storage is an important facility for seasonal and emergency natural gas peak shaving. The reservoir geological

conditions and injection and production processes of gas storage are quite complex, which make the design of injection and

production schemes of gas storage more difficult. Considering that the decision of injection and production schemes of gas

storage is affected by many factors, in order to obtain the best injection and production scheme of gas storage, this paper presents

a fuzzy comprehensive evaluation method to evaluate and optimize the injection and production of gas storage. Firstly, a fuzzy

comprehensive evaluation index system of gas storage injection and production is established as the basis of analysis and

evaluation. This index system includes the injection and production well numbers, injection and production well layers, injection

and production capacity, injection and production efficiency and injection and production energy consumption. Then the entropy

weight method and an analytic hierarchy process are used to calculate the index weights. Based on a fuzzy membership function

method, trapezoidal and ridge membership functions are selected to score the evaluation indexes. After the weight and score

of each index are obtained, a linear weighting method is used to calculate the comprehensive evaluation result of the injection

and production scheme. The whole paper focuses on the method and process of establishing a fuzzy comprehensive evaluation

model of gas storage injection and production, which mainly includes the establishment method of the evaluation index system,

the calculation method of index weight and the determination method of the index membership function. Domestic gas storage

in a depleted gas reservoir is taken as an example to evaluate and optimize the injection and production scheme. This gas storage

has a storage capacity of 5.88 ×108m3, a working gas capacity of 2.95 ×108m3 and an injection production well number of 13.

According to the gas injection and production arrangement of the gas storage, the planned annual gas injection volume is 2.0

×108m3 and the annual gas production volume is 1.5 ×108m3. Three gas injection schemes and three gas production schemes

of the gas storage are evaluated and optimized. The results show that the comprehensive scores of the evaluated gas storage

injection and production schemes are all above 70 points, indicating that the application effects of each scheme is good. Among

them, the optimal gas injection scheme is scheme 2, and the optimal gas production scheme is scheme 3. Finally, the evaluation

method proposed in this paper can provide guidance for the planning and management of injection and production of gas storage.
