| 摘 要： | 酸岩反应动力学参数是分析酸岩反应特征、评价酸液体系及酸压设计的关键基础参数,为正确分析酸岩反应速率规律、指导酸压施工设计提供基础。通过开展用于四川盆地川东下古生界-震旦系的180℃高温胶凝酸酸岩反应动力学实验,建立了酸岩反应动力学方程,得到了180℃、500 r/min、7 MPa条件下,酸岩反应级数m=0.696 9,反应速度常数K=1.09×10~(-4)(mol·L)~(-m)·mol/(cm~2·s),反应速度方程为J=1.09×10~(-4)C~(0.696 9);其活化能Ea=23 706 J/mol,酸岩反应动力学方程为J=0.070 5e~(-23 706/RT)C~(0.696 9);并明确了胶凝酸的温度、酸液浓度对反应速度的影响程度。
