摘要
阴离子非离子表面活性剂既能抗盐又能耐温,可以用于高温高盐油藏提高采收率。以OP10为原料,利用L酸等对其进行化学改性,合成了阴离子非离子两性表面活性剂。采用正交试验优化了合成条件,并评价了合成产品的界面活性。结果表明,合成的阴离子非离子两性表面活性剂具有较好的抗盐性和较高的界面活性。
Anionic-nonionic amphoteric surfactant,which is both salt resistance and temperature tolerance,can be used for enhancing the oil recovery in high temperature high salinity reservoirs. OP-10 is used as a raw material to perform a chemical modification with L acid,by which an anionic-nonionic amphoteric surfactant is synthesized,the synthesis conditions are optimized by using orthogonal tests,and the interfacial activity of the surfactant is evaluated. The result shows that the amphoteric surfactant has better salt resistance and interfacial activity.
