The invention relates to an automatic testing method of a wire line coring drilling hoisting-free pressurized water test. The method effectively solves the problems of accurately measuring the pressure in a pressurized water test section and fully exerting the advantages of automatic testing of the wire line coring drilling hoisting-free and pressurized water test. The method comprises the following steps of: drilling a rock by using a drilling tool, taking out the rock core when the drilled hole reaches the test length, uplifting a hollow drill rod, hoisting a pressurized water test embolismby using an inflatable rubber tube, filling the pressurized water test embolism into the hollow drill rod, making the pressurized water test embolism extend out of a drill bit at the lower part of the hollow drill rod, communicating the inflatable rubber tube and a nitrogen cylinder, charging air to the embolism, closing the hollow drill rod and the drilled hole, connecting a pressure sensor of the test section and a flow sensor outside the drilled hole to a pressurized water test comprehensive tester through cables, sealing with an orifice sealer, pressurizing water to the drilled hole section by using a water pump through the orifice sealer and the hollow drill rod, and acquiring data. According to the automatic testing method disclosed by the invention, wire line coring, pressurized water test and automatic testing are fused together, therefore the exploration quality and the exploration efficiency of deep holes in water conservancy and water electricity are greatly improved, and the labor intensity is effectively reduced.
