Problems solved by technology
During the injection-production operation of the porous gas storage, affected by many factors such as injection-production speed, operating pressure range, and water intrusion, it is impossible to simulate the reciprocating high-speed injection-production operation law and its impact on the operation of the gas storage by using conventional oil and gas reservoir development experiment methods. Influence of database construction and operation efficiency
Conventional experimental devices use mass flow controllers to realize gas injection and production. The type of gas controlled by such devices is single, and the range of gas flow and pressure controlled is limited. It is difficult to meet the large pressure range and high-speed injection and production of porous gas storage. The need for operational mechanistic studies

Description
technical field [0001] The invention relates to the technical field of porous gas storage, in particular to a gas storage physical simulation gas injection and production flow control system for controlling the injection and production gas flow during the actual periodic injection and production operation of the simulated gas storage in a laboratory. Background technique [0002] Underground gas storage is mainly a pore-type gas storage rebuilt from depleted oil and gas reservoirs. Therefore, before the construction of the gas storage, it is necessary to fully understand the original physical properties of the reservoir, and study the injection-production operation mechanism of the rebuilt gas storage and its main features. Influencing factors, especially the influence of gas injection and gas production flow rates on gas storage capacity parameters during injection and production operations, to guide the optimization of gas storage injection and production operation plans. ...
