聚合物、表面活性剂、碱的共同作用,是多年的热门研究课题,它对混合体系性能有着重要影响。本文通过测量混合物溶液电导率和界面张力,深入研究了两种阴离子表面活性剂十二烷基硫酸钠(SDS)和MarlonARL(MARL)在含有生物聚合物(黄原胶)和碱(NaOH)的溶液中的作用。由于三元复合驱(ASP)是最有前景的提高采收率方法之一,且油水界面张力是化学驱提高采收率最重要的参数之一,针对阿尔及利亚原油的特点,优化出三元复合驱的浓度(质量分数)配方:碱0.007,MARL0.02,聚合物0.002。测量结果显示,不同组分的混合物对电导率和界面张力有重要影响;同时,SDS和MARL两种表面活性剂的协同作用,在很大程度上也会影响三元复合驱和油水体系的电导率和界面张力。
The combined effect of polymers, surfactants, and alkalis, a hot research topic for many years, has important implications for the performance of mixed systems. In this paper, the effects of two kinds of anionic surfactants sodium dodecyl sulfate (SDS) and MarlonARL (MARL) on the biocompatibility of xanthan gum and alkali (NaOH) The role of solution. As ASP is one of the most promising methods to enhance oil recovery, and oil-water interfacial tension is one of the most important parameters for chemical flooding to enhance oil recovery. According to the characteristics of Algerian crude oil, ternary complex Drive concentration (mass fraction) Formula: Alkali 0.007, MARL0.02, Polymer 0.002. The measurement results show that the mixture of different components has an important influence on the conductivity and interfacial tension. Meanwhile, the synergistic effect of the two surfactants, SDS and MARL, will also affect the conductance of the ASP flooding and oil-water system to a large extent Rate and interfacial tension.
