| 摘 要： | 利用分光光度法和容量法分别考察了重芳烃石油磺酸盐（简称ＨＡＰＳ）与Ｃａ２＋、Ｍｇ２＋的沉积规律及在地层砂上的吸附规律．实验表明：当固定Ｃａ２＋、Ｍｇ２＋混合液浓度改变ＨＡＰＳ浓度时，ＨＡＰＳ与Ｃａ２＋、Ｍｇ２＋的作用呈现出沉淀——溶解——再沉淀的普遍规律，且沉淀量随着ＨＡＰＳ和Ｃａ２＋、Ｍｇ２＋混合液浓度的增加而增加；ＨＡＰＳ在地层砂上的吸附等温线呈“Ｓ”型，表现出多层吸附的特征．

| Abstract: | Heavy aromatics petroleum sulfonates (HAPS) are anionic surface active agent.
They can be made by sulfonating heavy aromatics, and have higher surface activities. In this
paper, the precipitating laws of Ca 2 , Mg 2 and HAPS and their absorbing laws on
stratigraphic oil bearing sand are investigated by spectrophotometric method and volumetric
method respectively. Laboratory research results show that, when the concentration of Ca 2
, Mg 2 is constant, but the concentration of HAPS is increased, the universal law of
precipitating dissolving reprecipitating occurs. The precipitation increases with the
concentration of Ca 2 , Mg 2 and HAPS. The absorption isotherm of HAPS on
stratigraphic oil bearing sand is sigmoid. |
