摘　　要：实验室制备了多氢酸,考察了多氢酸与地层水、交联酸添加剂等的配伍性,研究了以多氢酸为基液的多氢交联酸、以盐酸为基液的交联酸的酸岩反应动力学。实验结果表明,多氢酸交联酸与地层水、交联酸添加剂的配伍性良好,且以多氢酸为酸性基液的多氢交联酸在地层温度下无脱水、分层现象。多氢交联酸的反应速率远小于交联酸的反应速率,反应速率受酸液浓度的影响较小,多氢交联酸的氢离子传质系数更小,酸岩反应活化能更高,能够增大酸岩反应的活化能,可以有效降低酸岩反应速率,具有一定的缓速性能。The compatibilities between laboratory-made multi-hydrogen acid with formation water,cross-linked acid and its additives were studied.The acid-rock reaction kinetics of multi-hydrogen cross-linked acid and a hydrochloric cross-linked acid were investigated.The results show that multihydrogen cross-linked acid exhibited excellent compatibilities with formation water and additives,and had no dehydration and stratification at the formation temperature.The reaction rate of multi-hydrogen crosslinked acid was much lower than that of the cross-linked acid and less affected by the acid concentration.In addition,the hydrogen ion mass transfer coefficient of multi-hydrogen cross-linked acid was smaller,and the activation energy of acid-rock reaction was higher.It could increase the activation energy of the acid-rock reaction and effectively reduce the acid-rock reaction rate with a certain retarding performance.
