摘　　要：考察三次采油过程中所用的部分水解聚丙烯酰胺(HPAM)和疏水缔合型部分水解聚丙烯酰胺(AHPAM)结构与性质的差异,通过对其结构表征以及对其增黏性、耐温性和抗盐性的测试,结合扫描电镜(SEM)对两种聚合物溶液微观结构形态的观察,讨论疏水基团的存在对聚合物溶液性质的影响。结果表明,相对于HPAM,AHPAM溶液因结构中含有的疏水基之间的相互作用使高分子间进一步形成缔合的网络结构而具有良好的增黏性、耐温性和抗盐性。The structure and properties of partial hydrolyzed polyacrylamide （HPAM） and associating partial hydrolyzed poly- acrylamide （AHPAM） used in the tertiary oil recovery process were compared. Based on their structure characterization, the increasing viscosity characteristics, temperature resistance, salinity resistance were tested. The microstructure morphologies of two kinds of polymer solutions were observed by using scanning electron microscopy. The influence of the hydrophobic groups on the polymer properties was discussed. The results show that compared with HPAM, the property of AHPAM solu- tion is superior in the increasing viscosity characteristics, temperature resistance and salinity resistance due to the structure containing the hydrophobic grouping to form association among super-molecular structures.
