| 摘 要： | 针对双河油田稀油老区注水井层位多、夹层薄、层间吸水能力差异大等问题,利用粘弹性表面活性剂在酸液中表现出的粘弹性,以及破胶完全、对地层清洁无伤害的特点,通过配伍性、流变性、缓速性、转向分流性等室内评价实验找出了最优化的粘弹性酸化液体系,能够对渗透率存在差异的低渗透岩芯进行改造.

| Abstract: | The water injection wells which are in thin oil old liberated area of Shuanghe Oilfield have many formations,thin interbed,and large differences in absorbing capacity of interlayer.To solve these problems,take advantage of viscoelastic surfactant which has viscoelasticity in acidizing fluid,characteristics of gelout completely,and no harm to formation cleaning,to find the best viscoelastic acidizing fluid system through laboratory evaluation test of compatibility,rheological property and diversion flow property.This system can reform low permeable rock with different permeability. |
