摘要
本文从聚合物在吸附层中的基本构象出发,建立了饱和吸附量与含盐量、HPAM 分子量之间关系的数学模式,通过与 Langmuir 吸附等温式联立,进一步在吸附量与含盐量、HPAM 浓度、HPAM 分子量之间建立起数学关系,并应用实验数据对吸附量与含盐度之间的数学关系进行了验证。
A new mathematical relation is established between the adsorption of HPAM by min- erals from solution,the salinity,and the molecular weight and concentration of the polymer, starting from a Arrhenius equation of adsorption and based on the suggestion of random coil conformation of polymer molecules in adsorbed monolayers.The relation deduced is verified by the experimental data obtained on quartz sand,gaolinite,illite,feldspar,Anqiu clay,and a ground oil reservoir core,Daqing Oil Field.
