中文摘要：

以丙烯酰胺（AM）、丙烯酸（AA）、N–烯丙基咪唑（AI）及N，N–二烯丙基油酰亚胺（DXA）为原料，合成了一种水溶性四元聚合物AM/AA/AI/DXA，考察了反应条件对聚合反应的影响，确立了最佳合成工艺。通过红外光谱（IR）、核磁共振氢谱（1 H NMR）、扫描电镜（SEM）分析了目标聚合物的结构及溶液微观特征。结果表明：该聚合物具有良好的耐温抗剪切、抗盐性能。在60？C下驱替实验证明：与水驱相比，2000 mg/L的聚合物溶液可提高采收率达13.5%，驱油效果明显。钠蒙脱土在2000 mg/L聚合物溶液中水化后，晶层间距与清水相比由18.9532？降至16.6657？。

英文摘要：

A novel copolymer was synthesized using acrylamide,acrylic acid,N–allylimidazole and N,N–diallyl oleamide. The optimal conditions for synthesis such as temperature,pH,initiator and monomer loadings were studied. The viscosity measurements,and rheological measurement of the obtained copolymer were characterized by Infrared（IR）spectroscopy,H nuclear magnetic resonance spectrometer（1 H NMR）,scanning electron microscope（SEM）. X-ray diffractometer（XRD）were also conducted to investigate the clay stabilization property of the obtained copolymer. The results indicated that the copolymer was of good temperature tolerance,and anti-shear abilities and salt resistance. Core flooding result revealed that the enhanced oil recovery could be up to 13.8%. The result of X-ray diffractometer revealed a good clay stablility of sodium montmorillonite.
