摘要
阐述了灰岩与HC l之间的反应原理及各动力学参数的表达式,用旋转岩盘腐蚀测定仪,系统地测定了中1井20%胶凝酸的酸岩反应动力学方程,求取了反应活化能、酸岩反应速度常数、H+有效传质系数等酸岩反应动力学参数,可以为酸压优化设计提供可靠的依据。
The reaction between CaCO_3 and hydrochloric acid and the expressions of dynamical parameters are presented.Acid/rock reaction dynamics equation of 20% gelled acid in Zhong-1 well are determined using the Rotating Disc Apparatus.The reaction activation energy,the reaction rate constant and the effective H^+ mass transfer coefficient are obtained.Thus a reliable basis for optimum design of acid-fracturing is provided.
