高分子表面活性剂与原油形成超低界面张力的研究
Study on Ultra-low Interfacial Tension of Polymer Surfactants Crude Oil
【摘要】 对AM-AOPn和CMC-AR12EOn两类高分子表面活性剂与原油形成超低界面张力的研究结果表明,加碱复配后,AM- AOPn和 CMC- AR12EOn与大庆原油的界面张力分别可达 2.6 ×10-3mN/m和 3.2x 10-3mN/m。显微观察表明,碱使胶束解缔是界面张力降低的主要因素。
【Abstract】 The ultra-low interfacial tensions (IFT) between aqueous solutions of AM - AOPn. and CMC - AR12 EOn. polymeric surfactants and Daqing crude oil were studied.The results show that the IFT decreased to 2. 6 x 10-3 and 3 .2 x 10-3mN/m for AM -- AOPn. and CMC -- AR12 EOn. respectively with the addition of alkali. The microscopic observation showed that the disaggregation of micelles by alkali is the main reason for IFT decrease.
