| 摘 要： | 基于不同分子结构，探讨了表面活性剂分子与聚合物分子、高价金属离子的相互作用机理，认为与钙离子结合能力排序为：十二烷基硫酸钠> 部分水解聚丙烯酰胺> 十二烷基苯磺酸钠，从而导致聚–表二元复配体系黏度的差异。同时，驱油体系驱油实验的结果表明，驱油效率主要受到体系黏度、油水界面张力的影响，但驱油体系性能相近的情况下，具有更大分子截面积的表面活性剂，在驱替过程中，会表现出较好的界面张力保持能力，得到相对较高的驱油效率。

| Abstract: | Based on the different molecular structures，interaction mechanisms of surfactant interaction with polymer andhigh-valent metal ions were discussed. The bonding ability of calcium ions ranks as SDS > HPAM >SDBS，which results inthe different viscosities of surfactant/polymer binary systems. Experiments show that oil displacement efficiency was mainlyinfluenced by their viscosity and interfacial tension. However，for similar property systems，the surfactant with bigger molecularsurface cross-sectional area is more helpful to enhance oil displacement efficiency. To some extent，such surfactant wouldmaintain original interfacial tension while flooding. |
