以丙烯酰胺（AM）、丙烯酸（AA）、N，N-二烯丙基油酰胺（DNDA）、N，N-二甲基二烯丙基氯化铵（DMDAAC）为单体，合成了水溶性丙烯酰胺共聚物（PMADD）。利用FTIR、流变等方法分析了PMADD的结构，研究了PMADD的性能，并利用岩心驱替实验考察了PMADD对模拟原油的提高采收率能力。实验结果表明，合成PMADD适宜的条件为：m（AM）∶m（AA）∶m（DMDAAC）∶m（DNDA）=5∶5∶0.3∶0.04、聚合温度45℃、NaHSO3-（NH4）S2O8引发剂用量0.3%（w）（基于反应体系质量）、反应体系pH=7。PMADD具有良好的增黏、抗剪切、耐温、抗盐和耐老化性能。当PMADD的质量浓度为2000 mg/L时，其溶液的表观黏度为590.3 mPa·s；在剪切速率为1000 s-1时，其黏度保留率为7.0%；当NaCl质量浓度为12000 mg/L时，PMADD溶液的黏度保留率为23.7%。当模拟地层水的总矿化度为5200 mg/L时，2000 mg/L的PMADD溶液可提高模拟原油采收率12.64%。

A novel water-soluble copolymer(PMADD) was synthesized from acrylamide(AM),acrylic acid(AA),N,N-diallyl oleic-amide(DNDA) and diallyl dimethyl ammonium chloride(DMDAAC), and characterized by means of FTIR and rheology. The properties of PMADD for enhanced oil recovery were studied. The results indicated that the optimum conditions for the synthesis of PMADD were:m(AM)∶m(AA)∶m(DMDAAC)∶m(DNDA) 5∶5∶0.3∶0.04,45℃,reaction system pH 7 and initiator dosage 0.3%(w)(based on the mass of the reactants). When the PMADD concentration was 2 000 mg/L,the apparent viscosity of its solution was 590.3 mPa·s. The viscosity retention rate of PMADD was 7.0% at the shear rate of 1 000 s-1. When the NaCl concentration was 12 000 mg/L,the viscosity retention rate of PMADD was 21.7%. The enhanced oil recovery(EOR) could increase by 12.46% when the concentration of PMADD was 2 000 mg/L and the salinity of simulated formation water was 5 200 mg/L.
