Rock damage test device under flow coupling action of high temperature and acid solution

The invention discloses a rock damage test device under high temperature and acidic solution flow coupling effect, and relates to the technical field of rock damage test equipment, the rock damage test device comprises a water tank and a rock test piece, and also comprises: a solution inlet pipe; a furnace body shell; a controller; an acid solution flow simulation test mechanism; and a real-time variable high-temperature test mechanism is simulated. According to the invention, the acidic solution flowing rock damage test can be carried out on the rock test piece under the action of different PH values, different types of solutions and different flow rates through the arranged simulated acidic solution flowing test mechanism, and the simulated real-time variable high-temperature test mechanism can be used for carrying out high-temperature damage test on the rock test piece at different temperatures; the high-temperature damage test and the acid solution flow damage test can be carried out independently or simu
