| 摘 要： | 用胜利油田临盘采油厂的注入水配制不同含量的双子表面活性剂溶液,研究了双子表面活性剂溶液与临盘原油间的界面活性;并与传统表面活性剂十四烷基三甲基溴化铵(TTAB)进行了界面活性对比;考察了双子表面活性剂的疏水烷基长度和联结基长度、溶液中表面活性剂含量和温度对界面张力的影响,并对比了不同双子表面活性剂与不同原油间的界面活性。实验结果表明,三亚甲基-1,3-双(十四烷基二甲基溴化铵)(14-3-14)双子表面活性剂的界面活性明显优于TTAB;当14-3-14双子表面活性剂含量一定时,其溶液与临盘原油间存在最低界面张力;14-3-14双子表面活性剂可在较低含量下将其与临盘原油间的界面张力降至10~(-3)mN/m数量级;14-3-14双子表面活性剂适用于临盘原油,二亚甲基-1,2-双(十二烷基二甲基溴化铵)双子表面活性剂适用于孤岛原油,并为下一步现场应用提供了基础和依据。
