聚合物类型对油水界面性质影响研究

采用平面张力仪和表面粘弹性仪研究了部分水解聚丙烯酰胺（HPAM）和疏水缔合聚合物（HAP）对油水界面性质的影响研究结果表明，疏水缔合聚合物HAP可以显著降低煤油／模拟水体系界面张力，但对模拟油／模拟水体系界面张力影响较小；部分水解聚丙烯酰胺类聚合物CA对煤油／模拟水和模拟油／模拟水体系界面张力无明显影响。无论是煤油／模拟水体系还是模拟油／模拟水体系．随聚合物溶液浓度的增加，部分水解聚丙烯酰胺类聚合物CA均使体系界面剪切粘度逐渐增大。而疏水缔合聚合物HAP均使体系的界面剪切粘度先增加，后降低，而后再增加。部分水解聚丙烯酰胺（HPAM）相对分子质量较大时，HPAM溶液／模拟油体系的界面剪切粘度较大。

Research on effects of polymer types on oil/water interfacial property

Interfacial properties of the polymer including partially hydrolyzed polyacrylamide(HPAM) and hydrophobically associating polymer(HAP) solution/model oil are studied respectively by dataphysics interfacial tension meter and SVR-S interfacial viscoelastic meter.Results show that,HAP can decrease interfacial tension of kerosene/formation water obviously,but impact little on that of model oil/formation water.The effects of polymer CA on interfacial tension of kerosene/formation water and model oil/ formation water are neither obvious.Polymer CA can increase interfacial shear viscosity of both kerosene/formation water and model oil/formation water as concentration of which was increased.When concentration of HAP is increased,interfacial shear viscosity of systems experiences a process of increasing at first,then decreasing,and then increasing.Interfacial shear viscosity of HPAM solution/model oil is higher when relative molecular weight of HPAM is bigger.
