摘要
本文研究了１１３５型聚丙烯酰胺在大庆油田解集砂岩、岩心的吸附性质。并应用化学驱数值模型对实测参数进行拟合研究，获得吸附参数ａ＿（ｉ１）、和ａ（ｉ２）、ｂ结果表明，这三个参数对聚合物浓度及含盐量有明显的依赖关系。并为聚合物数值模拟研究和油田现场实验提供了重要的依据。
We studied the disaggregating sandrock and rock core prope- rties of 1135 polyacrylamide at Daqing Oil Field,made the fit test on experimental parameters by applying chemical driving numerical model, obtained theadsorption parameters a<sub>i1</sub>,a（i2） and b. The results provided that the adsorptionparameters are dependent on the concentration of polymer and the salt conte-nt,and some bases are important to numerical simulation study and practicalapplication of polymer in oil field.
