An experiment system for a water reciprocating movement law of a water drive oil and gas reservoir type gas storage comprises a water container, a displacement metering pump, a gas booster pump, a gas storage core model, a fluid flowmeter and a control analysis device, wherein the water container comprises a cavity and a piston; the piston divides the cavity into a first cavity body and a second cavity body; pressure between the first cavity body and the second cavity body keeps balanced; the displacement metering pump is connected with the first cavity body and used for quantitatively adding water into the water container; the gas booster pump is connected with the second cavity body and used for quantitatively inflating the water container with gas; the gas storage core model is connected with the first cavity body and used for simulating operation conditions of the gas storage in the reciprocating injection-recovery process; the fluid flowmeter is connected with the first cavity body and the gas storage core model and used for collecting the movement amount of water which flows into or is drained into the first cavity body; the control analysis device is used for controlling the experiment system to simulate the actual injection-recovery process of the gas storage and recording various experiment data. By collecting the experiment data in the injection-recovery operating process, a research basis is provided for analyzing the water movement law in the actual gas storage building and injection-recovery operating process.
