Abstract: Kinetics parameters of acid-rock reaction are basic parameters to analyze the character of acid-rock reaction, and evaluate the acid liquid system and acid pressure design, which provide the basis of analyzing reaction rate correctly and guiding acidizing/acid fracturing design. By conducting the kinetics experiments of jel acid/rock reaction at 180 ℃ in Sinian system of east Sichuan basin, the acid-rock reaction kinetics equation can be established. The results show that under the conditions of 180 ℃, 500 r/min, 7 MPa, acid/rock reaction order m=0.696 9, reaction rate constant K=1.09×10^-4(mol·L)^-m·mol/(cm²·s), reaction rate equation is J=1.09×10^-4C^{0.696 9}, its activation energy E_a=23 706 J·mol^-1, the acid rock kinetic equation is J=0.070 5e^{-23 706}/RTC^{0.696 9}. The effects of the temperature and concentration of jel acid on the reaction speed are determined.
