研究了体系中起泡剂和稳泡剂的吸附量并通过岩心流动实验，测定了起泡剂和稳泡剂在含油、不含油条件下的滞留量。研究结果表明，稳泡剂的吸附等温线呈“L”型，油砂上的饱和吸附量小于石英砂上的饱和吸附量；起泡剂的吸附等温线呈典型的“S”型，油砂表面上的吸附量总是小于在石英砂表面上的吸附量；稳泡剂和起泡剂的动态吸附量都小于在岩心砂上的静态吸附量，化学剂在含油岩心中的滞留量小于不含油岩心中的滞留量。

The adsorption of foaming agent and foam stabilizer in the system was studied. Dynamic absorption of foaming agent and foam stabilizer were measured with oil or without oil conditions. The results showed that the absorption isotherm of foam stabilizer were ‘L’ type. Saturation adsorption of foam stabilizer on oil sands was less than saturation adsorption on quartz sand. The absorption isotherm of foaming agent was‘S’ type. Saturation adsorption of foaming agent on oil sands was less than saturation adsorption on quartz sand. Static adsorption capability was higher than dynamic adsorption capability for both foam stabilizer and foaming agent. The retention of chemicals in oil cores were less than the retention of chemicals in no-oil cores.
