摘要
介绍了近年来pH响应型蠕虫状胶束的研究进展,包括pH响应型阳离子表面活性剂体系、pH响应型阴离子表面活性剂体系、CO_2响应型表面活性剂体系以及pH响应型两性表面活性剂体系,并对其发展前景进行了展望。pH响应型蠕虫状胶束具有易于控制、过程可逆、实现方便等一系列优点。新型耐温抗盐pH响应型蠕虫状胶束能满足驱油剂的黏度要求,具有很好的降低界面张力的能力,而且还可以减少在地层的吸附损失,在提高采收率领域更具有研究价值。
The progress on the research on pH -responsive wormlike micelles including pH -responsive cationic surfactant system, pH- responsive anionic surfactant system, CO2 -responsive surfactant system and pH- responsive ampholytic surfactant system in recent years is introduced, and the future development of pH -responsive wormlike micelles is discussed in this paper, pH -responsive wormlike micelles have several advantages like being easy to control, being reversible in process, and convenient application, etc. New heat resistant and salt tolerant pH - responsive wormlike micelles can satisfy the requirement for the viscosity of oil displacing agent, are capable of reducing the interfacial tension well enough, and can reduce formation adsorption. They have the value for studying how to enhance oil recovery.
