The invention provides a test method and a test system for simulating mining of shale oil. The test method for simulating exploitation of shale oil comprises the following steps: step S100, measuring the mass of a reservoir core sample, and sealing and fixing the reservoir core sample; s200, carrying out sound wave vibration on the reservoir rock core sample for a preset time length, and obtaining sound wave attribute parameters of the reservoir rock core sample; s300, carrying out microwave radiation heating on the reservoir core sample to a preset temperature in a constant-temperature environment, and keeping the preset temperature for a first preset duration; step S400, injecting supercritical carbon dioxide into the reservoir core sample, and soaking for a second preset time length so as to exploit oil and gas; and step S500, collecting decomposition products of the reservoir core sample, and recording the cumulative yield of the decomposition products. The method solves the problems that in the prior art
