In a vertical pipe, actual concentration of materials under delivery is greater than the one at its outlet due to lagging effect.
颗粒滞留效应 ,将导致在垂直管流中物料的当地浓度大于输送浓度。
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.
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。
