摘要
从分子设计的角度研究了适于胜利油田三次采油用表面活性剂系列改性木质素磺酸盐,考察了它对胜利原油的界面张力情况,结果表明改性木质索磺酸盐对胜利原油适应性非常好,在较宽的表面活性剂质量分数、碱质量分数和电解质质量分数范围内都可形成超低界面张力。
Modified lignosulfonates by polyamine for enhanced oil recovery applied to theShengli oil field was studied in terms of the molecular design. The interracial tension investigationshowed that the modified lignosulfonates had good adaptability to the Shengli crude oil, which could pro-duce ultra-low interfacial tension in a wide range of surfactant, alkali, and electrolyte concentrations.
