摘要： 为探究阴-阳离子表面活性剂复配微乳液体系驱油效果,研究了SDBS与DTAB的最佳摩尔比以及复配表面活性剂的总质量分数确定最佳微乳液配方,并将复配的微乳液体系与三元复合驱进行驱油效果对比,说明微乳液驱的驱油能力。实验结果表明,复配微乳液驱油体系最佳配方为:正辛烷5 mL,水5 mL,总质量分数为1.5%的SDBS与DTAB的摩尔比为1∶4,正丁醇的质量分数为4%,NaCl的质量分数为5.2%。与水驱相比,微乳液驱采收率增幅为6.48%~7.56%;与三元复合驱相比,微乳液驱采收率增幅为0.06%~0.35%。

Abstract: In order to explore the effect of crude oil flooding of the anionic and cationic surfactant blend microemulsion system,the optimized mole ratio between sodium dodecyl bezene sulfonate (SDBS) and dodecyl trimethyl ammonium bromide (DTAB) and the mass fraction of total surfactants were studied.Through comparing the crude oil flooding effect of the blend microemulsion system and that of the conventional three component oil flooding agent (ASP),the improvement for the crude oil flooding capacilty of the microemulsion flooding is indicated.Results show that the optimum formula of the blend microemulsion flooding system is suggested as:n-octane,5 mL;water,5 mL;1.5% mass fraction of SDBS and DTAB with molar ratio of 1∶4;mass fraction 4% of n-butanol;mass fraction 5.2% of NaCl.As comparing with water flooding,the recovery rate of microemulsion flooding increases from 6.48% to 7.56%.As comparing with ASP,the recovery rate of microemulsion flooding increases from 0.06% to 0.35%.

Key words: anionic and cationic blend surfactant, oil flooding efficiency, oil flooding mechanism
