聚/表二元复合驱油体系性能研究

Study on the Performance of Hydrophobical Associating Water-soluble Polymer and surfactant system

疏水缔合水溶性聚合物和表面活性剂之间存在着协同效应 ,这种效应有利于改善聚 /表二元复合驱油体系的驱油效果。研究了疏水缔合水溶性聚合物 (NAPs)与阴离子表面活性剂 (SDBS)体系的配方 ,及其流变性、界面特性以及驱油性能。结果表明 ,该二元体系表现出良好的流变性和低的界面张力 ,获得了较好的驱油效果。

There exists synergistic effect between hydrophobical associating polymer and surfactant,which can improve the sweeping efficiency of polymer and surfactant system.In this paper,formula,rheological properties,interfacial properties and sweeping efficiency of NAPs and SDBS system were studide and the results indicated that the dual-compound system showed excellent rheological performance and low interfacial tension,as well as satisfied sweeping efficiency.
