The invention provides a testing device for a water injection test and a testing method thereof.The device comprises a water stop sealing air bag which is movably arranged in a drill hole and can be inflated and expanded at a first set position in the drill hole and make contact with the hole wall of the drill hole so that a test section can be formed above the water stop sealing air bag; the water injection assembly is used for injecting water into the test section; the measuring assembly is arranged in the test section and is used for measuring the water level change in the test section; the testing method comprises the following steps: acquiring a change relation between water level and time in real time through the measuring assembly, and then calculating the permeability coefficient. The device is simple in structure and easy to operate, the water injection rate can be controlled, and a test result can be obtained in real time. 本发明提供一种用于注水试验的测试装置及其测试方法，该装置包括止水密封气囊，其可移动的设置于钻孔内，且可在钻孔内第一设定位置处充气膨胀并与钻孔的孔壁接触以使
