摘要
在丙烯酰胺、丙烯酸的基础上引入抗盐、耐温性能的N-芳基丙烯酰胺(N-AAM)和增粘、增溶性能的甲基丙烯酰氧乙基二甲基烷基溴化铵(MADA),从而实现聚合物耐高温高盐性能与其溶解性、增粘性的有机统一,其结构经红外光谱(FTIR)表征证实。评价了耐温抗盐聚合物(ATSP)的增粘、耐温、高温高盐长期稳定性、驱油等性能,并通过ESEM得到了其在高矿化度下的微观形貌。结果表明,耐温抗盐聚合物增粘、耐温性能优良,在高温高盐条件下稳定性好,聚合物驱及后续水驱的采收率为9.9%。
Introduced N-aryl acrylamide（ N-AAM ）and methyl acryloyl oxygen ethyl dimethyl alkyl am-monium bromide（ MADA）on the basis of acrylamide,acrylic acid,the polymer can realize the organic u-nity of thermal-salt resistance and its solubility and viscosity. Its structure was confirmed by FTIR. The properties of viscosity,thermal tolerance,long-term stability in high temperature and salinity,oil displace-ment of ATSP were evaluated. Its microstructure was observed under the condition of high salinity by ES-EM. The results showed that ATSP had a excellent viscosity and good stability of high temperature and high salinity. In addition,the recovery of polymer and subsequent water flooding was 9. 9%.
