摘　　要：以AM、AMPS为主要单体合成二元共聚物,对共聚物进行水解得到不同水解度的共聚物,测试不同水解度的共聚物增黏能力、抗剪切、抗温抗盐等性能。实验结果表明:AM/AMPS共聚物适合高温高矿化度油藏条件下的聚合物驱。在淡水条件下,不同水解度的共聚物随着水解度的增加,增黏能力、抗剪切能力、抗温能力先增加然后再降低,在水解度25%时增黏能力、抗剪切能力、抗温能力最好。在盐水条件下,随着水解度的升高,抗盐能力逐渐变差。Binary copolymers were synthesized with AM and AMPS as main monomers,the copolymers were hydrolyzed to get copolymers with different degree of hydrolysis,and the copolymers with different degrees of hydrolysis were tested for their viscosities,shear resistance,temperature and salt resistance.The results indicated that the AM/AMPS copolymer was suitable for polymer flooding under high temperature and high salinity reservoir conditions.Under fresh water conditions,the viscosity increasing ability,shear resistance and temperature resistance of copolymers with different degree of hydrolysis increased first and then decreased with the degree of hydrolysis increasing.When the degree of hydrolysis was 25%,the viscosity increasing ability,shear resistance and temperature resistance were the best.Under the condition of salt water,as the degree of hydrolysis increasing,the ability of salt resistance become worse.
