摘要
分别了研究了疏水缔合聚合物AP-P4不同相对分子质量时的油水界面张力、界面膜扩张模量、油水分配系数等界面性质,并利用双偏振光干涉技术研究了低相对分子质量AP-P4在不同原油组分油水界面的吸附行为,同时与HPAM进行了对比。实验发现:和HPAM不同,AP-P4能够降低油水界面张力,具有较强的乳化能力,同时能吸附在油水界面活性物质(沥青质和胶质)的表面,增强油水界面的扩张模量,从而增强聚驱采出液的稳定性。
The interface tension,interfacial dilatational modulus,oil-water partition coefficient of hydrophobic associating polymer(AP-P4)were investigated,especially,the adsorption of AP-P4 on the surfaces of different oil components was studied by dual polarization interferometry(DPI)for first time.In addition,the adsorption behavior of partially hydrolyzed polyacrylamide(HPAM)was also studied to be compared.The results showed that AP-P4 can reduce the interface tension and has good emulsifying capacity.It can adsorb on the surface of interfacial active substance of crude oil(including resin and asphaltene)and the viscoelasticity of interface could be increased.
