The invention discloses a test device for testing the permeability of a gas-liquid mixed medium. The test device comprises a liquid storage device, a gas storage device, an evaporator module, a loading system, a confining-pressure-free core holding device, a data acquisition instrument and a computation system, wherein the liquid storage device and the gas storage device are connected with two inlets of the evaporator module respectively; the loading system comprises a gas-liquid mixing pump and a high-pressure tube, the gas-liquid mixing pump is used for pressurizing a mixed gas output by the evaporator module, and the mixed gas is fed into a gas inlet of the confining-pressure-free core holding device through the high-pressure tube; an outlet of the confining-pressure-free core holding device is connected to a liquid flowmeter and a gas flowmeter through outlet pipelines; the data acquisition instrument acquires data of the evaporator module, the liquid flowmeter and the gas flowmeter; and the computation s
