摘　　要：由溴代烷、二溴代烷、3-氨基-1-丙磺酸等合成了N,N′-乙基-N,N′-丁磺基-N,N′-烷基-烷基二胺钠盐,采用表界面张力仪测试其在三次采油中应用的能力。结果表明,该系列两性双子表面活性剂具有超低油水界面张力,其油水界面张力可达10^(-2)～10^(-3)mN/m,并具有优秀的耐盐及抗温性能,能作为三次采油用表面活性剂。An amphiprotic gemini surface active agent was synthesized by bromoalkane,dibromo generation of alkanes,3-amidogen-1-propanesulfonic acid.The surface interface tensionmeter was used to test its ability in enhanced oil recovery.The results show that the amphiprotic gemini surface active agent has ultra low water interfacial tension as 10 -2 ~10 -3 mN/m and can be used as surfactant for enhanced oil recovery because it’s excellent salt tolerance and high-temperature resistance.
