| 摘 要： | 粘弹性表面活性剂自转向酸液体系是最近发展起来的一种非均质地层酸化处理新技术.相比于目前常用的转向酸液体系,该体系具有配制简单、破胶容易、对地层伤害少及缓速、降滤失的优点.在合适的外界条件下,该酸液体系依靠粘弹性表面活性剂排列结构的变化实现酸液的转向、破胶.为了更好地研究粘弹性表面活性剂自转向酸液体系,调研了中外关于粘弹性表面活性剂自转向酸液体系的研究现状及最新进展,并系统地总结了粘弹性表面活性剂自转向酸液体系的转向及破胶机理、自转向酸主剂的选择原则、酸液体系的流变性分析.同时,对粘弹性表面活性剂自转向酸液体系的转向性能及反应动力学方面的研究也进行了详细说明.最后,提出了粘弹性表面活性剂自转向酸液体系下一步的工作重点和研究方向.

| Abstract: | Viscoelastic surfactant self-diverting acid system is the newly developed technique for heterogeneity formation treatment. Compared to the common diverting acid system,the system has the advantages of formulating easily,gel-breakage easily, and low damage to the formation,in addition,it has the low reaction rate and low filtration.Under the suitable external conditions, this acid system relies on the change of the structure arrangement in the viscoelastic surfactant so as to achieve the acid diverting and g... |
