The invention discloses an automatically controlled acid-rock reaction kinetic parameter experimental apparatus, which belongs to the technical field of petroleum engineering. The objective of the invention is to overcome the technical problems of inaccurate measured kinetic parameters and discontinuous experiment operation caused by easy fluctuation of temperature and pressure in a reaction vessel in the prior art. The apparatus comprises a high pressure reaction vessel with a self-heating function; the high pressure reaction vessel is respectively connected with a pressure stabilizing system, a preheating system and a sampling system; the top of the high pressure reaction vessel is provided with a mixer shaft, the lower end of the mixer shaft extends into the high pressure reaction vessel and is provided with a thermoplastic pipe, and the upper end of the mixer shaft is in transmission connection with the output shaft of an agitator motor. The apparatus provided by the invention enables experimental conditions of an acid-rock reaction to be automatically controlled in the states of constant temperature and constant pressure, improves accuracy of determination of each kinetic parameter and continuity of experiment operation, is applicable to experimental determination of acid-rock reaction kinetic parameters in petroleum engineering and has high determination precision and a high automation degree.
