Multi-round injection and production gas phase state experimental device for gas storage

The utility model provides a gas storage multi-round injection and production gas phase state experiment device. The gas storage multi-round injection and production gas phase state experiment device comprises a high-temperature and high-pressure PVT chamber used for carrying out multi-round injection and production gas phase state experiments; the high-temperature and high-pressure PVT chamber and the gas injection mechanism used for providing injection gas for the high-temperature and high-pressure PVT chamber are arranged, a stable experimental device capable of being simulated is provided for the multi-round gas injection and production experimental process of the gas storage, meanwhile, the high-temperature and high-pressure PVT chamber and the gas injection mechanism are arranged, the influence of the experimental environment on indoor simulation is greatly reduced, and the experimental device is easy to operate and low in cost. A reliable experiment process is provided for simulating multi-turn gas inj
