从烃的角度,用C_6到C_(20)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C_6烃能得到W/O型微乳液能连续转变到O/W型,而C_(20)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。
From the point of view of hydrocarbons, the influence of C_6 to C_20 aliphatic hydrocarbons and some aromatic hydrocarbons on the formation of microemulsions in sodium dodecyl sulfate (AS), butanol and water systems was investigated. The research approach is to find out the maximum moisture content of the microemulsion in the region where the microemulsion is formed from the four component phase diagrams of AS, butanol, water and hydrocarbons; and the interfacial tension in the formation of the microemulsion by phase diagram determination Other properties. This article focuses on the influence of hydrocarbon molecular weight, structure and content, and finds out C_6 hydrocarbons can get W / O type microemulsion can continuously change to O / W type, while C_ (20) above hydrocarbon can not form microemulsion . Finally, the law of its interpretation and theoretical discussion. These laws are also instructive for tertiary recovery.
