摘　　要：针对中原油田的实际情况,通过动态界面张力、正交试验设计,研究了天然羧酸盐/复碱/DSB(十二烷基羟丙基磺化甜菜碱)驱油体系的性能,得到ASP复合驱油体系配方(w/%):0 4SDC-M(天然羧酸盐-M)/0 08DSB(十二烷基羟丙基磺化甜菜碱)/0 5复碱(m(Na2CO3)∶m(NaHCO3)=1∶1)。研究结果表明,所提出的复合驱油体系与中原原油的界面张力能达到10-3mN/m,是一种优良的驱油体系。In accordance with the actual situation of Zhongyuan Oilfield,the performance of carboxylate/blend alkaline/DSB flooding system was studied.Through the determination of dynamic interfacial tension and by the orthogonal experimental design,a formulation of ASP blended flooding system was derived as(w/%):0.4 SDC(carboxylate-M)/0.08 DSB(dodecyl-hydroxyl-propyl-sulfo-betaine)/0.5 blend alkaline(m(Na_2CO_3)∶m(NaHCO_3)=1∶1).Test result shows that the interfacial tension between the flooding system and the Zhonyuan crude oil can achieve 10^(-3) mN/m,and the performance of the flooding system is excellent.
