| 摘 要： | 针对一种阳离子聚合物型相对渗透率调节剂，研究了RPM 在不同润湿性砂子上的静态吸附以及选择性堵水
性能。实验结果表明：RPM 在油砂和石英砂上均发生单层吸附，且石英砂上的静态吸附量（1 110 μg/g）是其在油砂上
的吸附量的2 倍以上；吸附剂表面润湿性和聚合物链节的带电性是影响吸附量的两个重要因素；RPM 的吸附可以使
油湿石英表面（105°）转变为弱水湿（72°）；采用了岩芯驱替实验研究RPM 的选择性堵水能力：油、水相残余阻力系数
随着渗透率、温度以及矿化度的增加而下降，聚合物吸附层的膨胀/收缩是RPM 选择性堵水的合理解释。

| Abstract: | The static adsorption and selective water shutoff performance of a cationic polymer type relative permeability modifier（
RPM）were studied. The results show that the static adsorptions of RPM on quartz sands and oil sands are both langmuir
adsorption，and the adsorption on quartz sands is twice of that on oil sands；the static adsorption is strongly affected by electrostatic
attraction and the wettability of solid surface，and RPM can alter the oil wet surface（105°）to weakly water wet（72°）；
core flood tests are conducted to study the selective water shutoff of RPM，and it shows that the oil and water residual resistance
factors decreases with the increase of permeability，temperature and brine salinity. The swelling/shrinking of polymer
adsorption layer is a reasonable explanation for RPM selective water control. |
