摘要
采用静态吸附法研究了在高矿化度，高钙、镁离子浓度水中的阳离子表面活性剂（Ｊ７６８）的吸附特性，研究用岩心为中原油田马寨油砂。通过吸附实验探讨了温度、ｐＨ值等因素对其吸附的影响。结果表明，阳离子表面活性剂在岩心上的吸附主要是靠静电作用。根据这一吸附机理，合成了３种能有效地抑制阳离子表面活性剂吸附的配合物，使其在岩心上的吸附量降低了８８．０２％。
The charateristics of cationic surfactant in alkaline solution of high salinity and hardness, absorbed by the Mazhai oil sand in the Zhongyuan oilfield is studied by static absorption method The effect of temperature,pH value,and so on,on its absoption is discussed. The result shows that the absorption loss is caused mainly by electrostatic action Several complexs are synthesized and used to inhibite the absorption of the cationic surfactant,with a declining rate of 8802%.
