| 摘 要： | 探索和研究表面活性剂在砂岩表面的吸附特性,对于正确选择表面活性剂及其使用浓度,开发新型、高效、功能型表面活性剂具有重要意义.采用Materials Studio(MS)软件,以二氧化硅作为理想岩层,以十二烷基苯磺酸钠和硬脂酸钠两种油田常用表面活性剂为研究对象,建立了一个含水的多晶胞模型.通过动态模拟表明:十二烷基苯磺酸钠比硬脂酸钠更易发生聚集,使临界胶束浓度降低;温度稳定快,最终温度高;能量稳定慢,最终能量低.为今后油田用表面活性剂的选择和新型高效表面活性剂的开发提供了一种可借鉴的方法. |

| Abstract: | Two surfactants widely used in oilfield-SDBS(sodium dodecyl benzene sulfonate) and sodium stearate being taken as research objectives,and silica as rock,the multi-crystal cell models of two surfactants are established using Materials Studio(MS)software.The dynamic molecular simulation results show that,the molecules of SDBS more easily gather than those of sodium stearate,which makes its CMC(critical micelle concentration) lower;SDBS more quickly reaches to stable temperature,its final temperature is higher;SDBS more slowly reaches to stable energy,and its final energy is lower.The results can provide reference for the selection of oilfield surfactants and the development of new high-performance surfactants. |
