SDBS/DTAB复配微乳液驱与三元复合驱驱油效果研究
Study on crude oil flooding effect of SDBS/DATB blend microemulsion flooding agent and conventional three component flooding agent
摘要
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%.关键词
