The physical simulation study on the gas-drive multiphase flow mechanism of aquifer gas storage is different from that of routine gas-oil reservoir,it mainly solves the simulation of gas-drive flow mechanism of gas storage in the condiuion of repetitious injection-production,so from experiment design and flow,it has its particularity and complexity,and at present,it has few reports on the domestic and foreign papers.From independent design and study on the physical simulation experiment flow of aquifer gas.
