Surfactant flooding, a chemical enhanced oil recovery (EOR) technique, mainly aims at mobilizing the trapped residual oil by lowering the oil-water interfacial tension. The success of a surfactant flooding operation is strongly affected by surfactant loss through its adsorption on reservoir minerals. Therefore, the adsorption behavior of surfactants is of great importance and needs to be carefully investigated. The present study provides an insight into the adsorption behavior of a recently proposed surfactant, namely Aerosol-OT, on a number of minerals — including quartz-sand, kaolinite, illite, and montmorillonite — under different salinities and temperatures. The examination was carried out in the form of batch experiments, and the surface tension technique was implemented to determine the adsorption rate. The adsorption equilibrium data were examined through two adsorption isotherm models known as Langmuir and Freundlich. It was found that the adsorption rate increased with the increasing salinity, where the highest value was observed for kaolinite (21 g/kg). However, an opposite trend occurred for temperature with the lowest adsorption rate (1.68 g/kg) was obtained for quartz-sand at 85 °C. The adsorption rate of Aerosol-OT was found to be higher than the conventional surfactants. A good correlation was seen between the equilibrium adsorption data and Langmuir isotherm model as their correlation coefficient ($R^2$) exceeded 0.999. The results provide a useful tool to screen surfactants for the chemical EOR operation in clay-rich reservoirs.

表面活性剂驱油是一种化学增强油采收率（EOR）技术，其主要目的是通过降低油水界面张力来移动被捕集的残余油。表面活性剂驱油作业的成功很大程度上受表面活性剂通过吸附在储层矿物上的损失所影响。因此，表面活性剂的吸附行为非常重要，需要仔细研究。本研究提供了一种新近提出的表面活性剂，即Aerosol-OT，在不同盐度和温度下对多种矿物（包括石英砂，高岭石，伊利石和蒙脱石）的吸附行为的见解。以分批实验的形式进行检查，并采用表面张力技术确定吸附速率。通过两个称为Langmuir和Freundlich的吸附等温线模型检查了吸附平衡数据。发现吸附速率随盐度的增加而增加，其中高岭石的吸附值最高（21 g / kg）。但是，在85°C的石英砂中，最低的吸附速率（1.68 g / kg）出现了相反的趋势。发现Aerosol-OT的吸附速率高于常规表面活性剂。平衡吸附数据和Langmuir等温线模型之间具有良好的相关性，因为它们的相关系数为（在85°C下，石英砂的最低吸附速率（1.68 g / kg）出现了相反的趋势。发现Aerosol-OT的吸附速率高于常规表面活性剂。平衡吸附数据和Langmuir等温线模型之间具有良好的相关性，因为它们的相关系数为（在85°C下，石英砂的最低吸附速率（1.68 g / kg）出现了相反的趋势。发现Aerosol-OT的吸附速率高于常规表面活性剂。平衡吸附数据和Langmuir等温线模型之间具有良好的相关性，因为它们的相关系数为（${\mathrm{[R}}^{\mathrm{2个}}$）超过0.999。该结果提供了一种有用的工具，可筛选用于富粘土储层中化学EOR操作的表面活性剂。
