十二烷基苯磺酸钠与非离子氟碳表面活性剂复合驱油剂的研究

Study of dodecyl benzenesulfonic acid sodium salt with non-ionic fluorocarbon surfactant sodium composite displacing agent

研究了十二烷基苯磺酸钠(SDBS)/氟碳Intechem-01表面活性剂(FC-01)复合驱油剂的性能,以驱油率、界面张力、与注入水和模拟地层水的配伍性为考察指标,正交实验结果表明,氟碳Intechem-01表面活性剂的质量分数为0.05%,十二烷基苯磺酸钠的质量分数为0.15%,碳酸钠、碳酸氢钠的质量分数都为0.25%时,复配体系的效果较好,且复配体系与定边油田采油注入水和模拟地层水有良好的配伍性。

Research on dodecyl benzenesulfonic acid sodium salt （SDBS）/fluorocarbon Intechem-01 sur- factant（ FC-01 ） composite displacing agent of performance, take the rate of metal mesh oil wash and static flooding, interfacial tension, and the injected water and formation water simulation compatibility testing as the indexes, the orthogonal experiment showed that mass fraction：fluorocarbon Intechem-01 surfactant 0.05%, sodium dodecyl sulfonate 0.15% ,sodium carbonate and sodium bicarbonate are both 0.25% ,the dynamic of the compound system with the Dingbian oilfield injection water and simulated formation water has good compatibility.
