| 摘 要： | 本文研究了烷基苯磺酸钠组成油层岩石主要矿物及天然岩样体系的吸附等温线,等温线通过一个最大吸附值,不符合Langmuir吸附模型。在表面活性剂溶液中,加入不同模数的硅酸钠,部分水解聚丙稀酰胺,SP型聚无机电解质或其他各种比例的混合物,都能不同程度地抑制表面活性剂的损失。表面活性剂溶液通过人造和天然岩心的渗流试验得到的结果同上述一致。

| Abstract: | The adsorption isotherms of alkylbenzene sulfonate on natural core and main minerals that are normally present in reservoir rocks have been investigated. A maximum is observed in the adsorption isotherms, which is not in line with the Langmuir adsorption model. The surfactant loss can be prevented to different degrees by adding sodium silicate in different SiO2/Na2O ratio, partially hydrolyzed polyacrylamide. SP type polyelectrolyte or their mixtures of various proportions in the surfactant solution.The results obtained from flow test in which the surfactant solution passed through the artificial and the natural cores are in accord with those above descibed. |
