摘要
论述了现阶段国内外采用化学剂驱油产生色谱分离的研究现状,并提出了三元复合驱油体系色谱分离的研究方法.结果表明:三元复合驱油体系出现的色谱分离现象是由于驱替过程中油层和化学剂之间的竞争吸附、离子交换、液-液分配、多路径运移和滞留损失等多种因素引起的.采用无因次突破时间和无因次等浓距两个指标来描述三元复合驱油体系的色谱分离程度.
The researches of chromaticgraphic separation of chemical flooding (surfactant of alkline/polymer) are outlined. The research method of chromaticgraphic separation of surfactant/alkline/polymer flooding is given. The chromaticgraphic separation of surfactant/alk line/polymer flooding is controlled by several factors, such as competing adsorption between oil zone and chemical agents, ion exchange, liquid liquid distribution, multipath movement and detention loss. The degree of chromaticgraphic separation of surfactant/alkline/polymer flooding can be described by means of normalized breakthrough time and normalized equal concentration distance.
