As the number of global gas reservoirs goes into operation, the safe operation of gas storage and the ability of injecting and withdrawing gas have gradually become the focus of the industry. According to the theory of reliability and operation of gas storage, the reliability of gas injection and production in gas storage is studied by a variety of methods such as Monte Carlo and K / N redundancy system. The research contents include the establishment of reliability evaluation index of gas storage system, the reliability calculation of gas storage system, the simplification and calculation of gas injection process of gas storage system, and the establishment of the reliability calculation model of main equipment affecting the gas injection and production capacity of gas storage . Applying the research results to calculate the related equipment, units and system reliability in the process of injection and production of a gas storage, the results can reflect the variation rules of the reliability of injection and production of gas storage equipment, units and systems with the process parameters and operating time, It is of important engineering significance to guide the gas storage tank to be reasonable and safe to operate and to improve the injection and production capacity of the gas storage.
