摘要
本文研究的体系组成是以玉门石油磺酸盐(3A)为表面活性剂,异丙醇和正丁醇复配为助剂,矿化水和玉门老君庙L层原油与玉门炼油厂灯用煤油混合为模拟油。文中着重研究了醇的配比、醇含量和模拟油中原油含量,对所形成微乳液的相态及共有关特性参数(最佳含盐度S~*,三相区盐宽ΔS、增溶参数、界面张力)的影响,并和以正癸烷为油相的结果进行了比较。本文所得规律对三次采油工作具有指导意义。
<ABSTRACT> The system composition studied in this article contains the
Yumen petroleum sulphonate ( 3A ) as interfacial activator, isopropanol and
n-butanol duplex componud as assistant activator, and a mixture of
mineralized water, the crude of Yumep Laojunmiao L-bed and the lamp kerosene
from Yumen Refinery as the simulatiating oil. The paper emphatically
stadics the effects of the alcohol compound ratio, the alcohol content and
the crude content in the simulating oil on the phase behavior o the formed
microemulsion and its relavent characteristic parameters ( the optimum salinity, the salinity range in 3-phese area,
parameters and the interface tension ), and compares the experimental results with
that from using n-decane as the oil phase. The rules worked out in this paper are
believed to be of guiding signitieance for tertiary recovery. the solubilized
