The invention belongs to the technical field of energy-consumption calculation methods, and specifically relates to an energy-consumption calculation method of a ground injection-production system ofgas storage of a depleted gas reservoir. According to the method, the injection-production system is divided into four key units, energy-efficiency evaluation models are respectively established, energy consumption in a period from entering of natural gas to a gas injection system to entering of the natural gas to an external-transmission system can be conveniently and accurately evaluated, and anenergy-consumption amount of the natural gas in the injection-production system can be intuitively characterized. The method can comprehensively evaluate an energy-efficiency level of the injection-production technology system of the gas storage of the depleted gas reservoir, and is a scientific and systematic method provided for realizing efficiency evaluation of the injection-production systemof the gas storage of the depleted gas reservoir and energy-efficiency comparison of same-type ground systems of gas storage.
