摘要： 基于酸与白云岩在温度控制下的反应动力 学模式,结合开发的新型交联酸体系展开了相关室内研究。介绍了酸与白云岩反应动力学行为测试原理及方法,测试了交联酸与现场白云岩反应动力学行为,得到了不同条件下的交联酸反应动力学参数及反应动力学方程,并在相同试验条件下对比了现场普通酸和稠化酸与白云岩的反应动力学特征。交联酸低反应速率、低有效传质系数的反应动力学行为将有利于降低酸液滤失,达到深部酸压改造的目的。

Abstract: Based on the reaction kinetics models between acid and dolomite under the control of temperature, integrated with newly developed cross-linked acid system, the experimental research is conducted. The testing principle and method for reaction kinetics behaviors between acid and dolomite are presented and tested. The related parameters and equations on them in different conditions are obtained. The correlation of field common acid and gelled acid with dolomite is made in the same testing condition. It is concluded that such reaction kinetics behaviors as low reaction rate and low effective mass transfer coefficient of the cross-linked acid will be favorable for reducing the acid filtration loss for the purpose of deep acid fracturing treatment.

Key words: acidizing, dolomite, cross linking, test, reaction rate, kinetics
