摘要
利用正交实验设计研究了聚合物A、石油磺酸盐B、表面活性剂C三种因素共存时对原油模拟油/水界面剪切粘度的影响。单因素实验表明,表面活性剂C使原油模拟油/水界面粘度降低,而聚合物A的存在则使油/水界面剪切粘度上升。而三种因素共存时,在实验条件下,表面活性剂C对油/水界面剪切粘度有一定的影响,聚合物A和石油磺酸盐B看不出有较大影响。因此,在聚合物-表面活性剂复合驱体系中,界面剪切粘度的变化主要取决于体系中表面活性剂的变化。
The L16 （4^5） orthogonal experiment was selected to investigate the effects of polymer A ,petroleum sulfonate B, and surfactant C on the interfacial viscosity of model crude oil, when three factors were coexisted in o/w emulsion. The results indicate that the interfacial viscosity between model oil and aqueous phase gradually decreases with the increase of surfactant C concentration but increases with the increase of polymer A concentration. When three factors were coexisted in o/w emulsion,the surfactant C has the effect on interfacial viscosity between model oil and aqueous phase in the complex system. And the effect of polymer A and petroleum sulfonate B on the interfacial viscosity is the weakest among the three factors under the experimental conditions. The interfacial viscosity of polymer-surfactant complex system is due to the surfaetant of the system.
