用 AMPS、AM、DMDAAC、S 型单体(含磺酸基长链烷基两亲表面活性单体)合成了耐温抗盐聚合物驱油剂 ZYS,借助红外光谱研究了单体及共聚物的结构,系统评价了产物ZYS 的驱油性能。结果表明,合成共聚物在总矿化度1.6×10~5mg/L(其中 Ca~(2+)、Mg~(2+)总量为3000mg/L)的人工盐水中具有良好化学稳定性,经90℃、180d 老化后仍能保持较高粘度。
The temperature-resistant and salt-resistant polymer flooding agent ZYS was synthesized by AMPS, AM, DMDAAC and S monomers (containing sulfonic acid long-chain alkyl amphiphilic surfactant). The effects of monomer and copolymer The structure of ZYS was systematically evaluated. The results showed that the synthesized copolymer had good chemical stability in artificial brine with a total salinity of 1.6 × 10 ~ 5 mg / L (Ca 2+ and Mg 2+ were 3000 mg / L) After 90 ℃, 180d aging can still maintain a high viscosity.
