摘要: 从烃的角度,用C6到C20的脂肪烃和一些芳烃,在十二烷基磺酸钠(AS),丁醇和水体系中,对其形成微乳状液的影响。研究手段是从AS、丁醇、水和烃的四组分相图中,找出形成微乳液的区域,微乳液所具有的最大含水量;以及通过相图测定形成微乳液过程中的界面张力等性质。本文着重考虑烃类分子量,结构和其含量的影响,从中找出C6烃能得到W/O型微乳液能连续转变到O/W型,而C20以上烃就不能形成微乳液等规律。最后对其规律进行解释和理论上探讨。这些规律对三次采油也具有指导意义。

Abstract: The mechanism of microemulsion is studied with particular emphasis on the effect of molecular weight, structure and concentration of hydrocarbons are inclusive of the fatty hydrocarbons from C6 to C23 and some aromatic hydrocarbons. The areas of microemulsion formation as well as the maximun water content of O/W microemulsion are found. Some rules are worked out as theoretical discussions have been attempted, which are belived to be of practical importance to tertiary oil recovery.
