石油羧酸盐与重烷基苯磺酸盐复配体系性能研究

通过石油羧酸盐与重烷基苯磺酸盐复配后的体系在弱碱（Na₂CO₃）条件下分别与大庆采油三厂和大庆采油六厂的油水发生作用,对体系的界面张力性能和模拟驱油效率进行检测,同时进行了体系界面张力稳定性试验。结果表明,该复配体系具有优良的界面张力,模拟驱油效率达20%左右,稳定性良好,并且可大幅度提高原油采收率。

Study on behaviour of petroleum carboxylate and heavy alkybenzene sulfonates mixing system

By action of the petroleum carboxylate and heavy alkylbenzene sulfonates mixing system respectively with oil-water of Daqing No.3 Oil Production Factory and No.6 Oil Production Factory in the alkalescence (Na_2CO_3) condition.The intcrfacial tension and displacement efficiency were tested,and the intcrfacial tension stability was tested simultaneously.The result showed that the mixing system had well intcrfacial tension,displacement efficiency was about 20%,the stability was favorable,and oil recovery was i...
