摘　　要：针对聚合物基稠化酸体系对地层存在潜在伤害的问题,研制出一种表观粘度随pH值升高而增大的甜菜碱类变粘分流酸,而且具有较好的缓速效果。介绍了变粘分流酸的pH值特性;通过旋转岩盘酸岩反应速率测试仪,研究了变粘分流酸的酸岩反应动力学方程、反应活化能、频率因子和H+传质系数,分析了变粘分流酸的缓速机理。In allusion to the potential problem of formation damage caused by dense acid of polymer,a new viscosity-variable-diverting-acid was developed based on the a new amphoteric surfactant whose viscosity increases with the ascension of pH,that was called the oleic amide proyl betaine,and it had better inhibition.The pH characteristics of the viscosity-variable-diverting-acid was introduced.By the experimental study on acid/rock reaction dynamics for carbonate reservoirs' cores and the viscosity-variable-diverting-acid,the kinetics equation,reaction activating energy,frequency restoration factors and hydrogen conduction coefficient of acid-rock reaction are studied,the delay reacting mechanism is analyzed.
