| 摘 要： | 通过对新型疏水缔合聚合物和表面活性剂二元体系的流变性及其聚表体系与模拟油之间的界面张力的研究,发现新型疏水缔合聚合物NAPs与表面活性剂SDBS之间存在明显的相互作用,并在一定条件下出现协同效应,聚表体系的体相粘度在某一表面活性剂浓度下出现最大值。聚表相互作用使它与模拟油之间出现最低界面张力的表面活性剂浓度增加,且界面张力要高于单独表面活性剂溶液与模拟油之间的界面张力。

| Abstract: | The rheology of hydrophobic associating polymer/surfactant solution system and the interfacial tension between the system and simulation oil have been studied in this paper. Experimental results show that there are obvious interactions between hydrophobic associating polymer ( NAPs) and surfactant(SDBs), and synergistic effects exist in some conditions. Maximum viscosity of the NAPs/SDBS system has got at certain surfactant concentration. The interaction of NAPs/SDBS has made the surfactant concentration shifts right at which the minimum interfacial tension between polymer/surfactant and simulation oil obtained, and increases the interfacial tension. |

| Keywords: | hydrophobic associating polymer surfactant rheology interfacial tension enhanced oil recovery |
