| Abstract: | The retarding property of acids is the key factor that determines the effective distance of acid, and is an important basis for selecting acid fracturing fluid. Experiments about acid-rock reaction between hydrochloric acid, gelled acid, emulsified acid and limestone cores of the Sarvak reservoir in Yadavaran oilfield of Iran were conducted respectively by a rotating rock disk, then reaction kinetic equations and variable temperature kinetic equations were constructed. The results indicate that the reaction rate of hydrochloric acid is significantly faster than that of gelled acid and emulsified acid, and temperature have a significant effect on acid-rock reaction rate, the higher temperature, the faster reaction rate is. At 95 °C, the reaction rate constants of hydrochloric acid, gelled acid and emulsified acid are 6.1745×10-5 (mol/L)-0.8543/(cm2.s), 7.8397×10-6 (mol/L)-0.6260/(cm2.s) and 7.6348×10- |
