Salt cavern gas storage twin-well building visual physical simulation system and method

The invention discloses a salt cavern gas storage twin-well building visual physical simulation system and method, and belongs to the technical field of salt cavern underground storage building. The system comprises a twin-well cavity building physical simulation subsystem and a twin-well gas injection and brine discharge physical simulation subsystem; the twin-well cavity-building physical simulation subsystem is composed of a water injection system, an oil injection system, a brine measuring system, a cavity-building form monitoring system and a simulation tubular column system. The double-well gas injection and brine discharge physical simulation subsystem is composed of a gas injection system, a brine discharge system, a flow field test system and a simulation tubular column system. The invention further provides a salt-cavern gas storage twin-well building visual physical simulation method. According to the technical scheme provided by the invention, large-size type salt is adopted to perform different s
