Abstract:Acid rock reaction kinetics experiment is to study the acid rock reaction mechanism and necessary means of acidizing design, the accuracy of the acid rock reaction kinetics parameters of its value, acid fracturing construction directly affects the design calculation and acid fracturing effect the accuracy of analysis. According to jingbian south carbonate reservoir, choose different acid formula, the acid rock reaction and kinetic parameters are also different,needs to through laboratory test method to determine. In this paper, using the tester, rock plate rotating at 100 ℃, 120 ℃, 7 mpa, different speed conditions, the time limit for 5 min, respectively, of gelled acid, crosslinking acid and steering acid three acid system acid rock reaction kinetics parameters were determined, and the system of different acid rock reaction kinetics equation, analysis the influence of various factors on the reaction rate, quantitative comparison of different acid system and rock reaction characteristics, designed for acidification, acidification simulation provide technical parameters.
