阳离子表面活性剂吸附规律的研究

A Study of Absorption of a Cationic Surfactant on the Mazhai Oil Sand in the Zhongyun Oilfield

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 8802%.
