摘要:
利用反相乳液聚合方法合成了AM/AMPS/疏水单体M（氯化甲基丙烯酸二甲基十六烷基氨基乙醇酯）/刚性单体S（4-丙烯酰基氨基苯磺酸钠）的四元疏水缔合聚合物AAMS-1，并用红外光谱对聚合物进行了结构表征。热重分析表明，聚合物在250℃下化学结构稳定。合成的聚合物乳液平均粒径在2 500 nm左右，其临界缔合浓度为0.15%。利用扫描电镜清楚观察到了AAMS-1压裂液的网状结构。AAMS-1压裂液具有良好的黏弹特性、携砂性能和岩心伤害特性。耐温耐剪切测试表明，体系具有优良的耐温能力，0.6%的水溶液在150℃、170 s-1条件下剪切2 h，表观黏度保持在50 mPa·s以上。
Abstract:A hydrophobically associating quadripolymer, AAMS-1, was synthesized through reverse emulsion polymerization, using AM, AMPS, hydrophobic monomer M (2-Dimethyl hexadecaneaminomethacrylate chloride)/rigid monomer S (4-acrolylamino sodium benzenesulfonate). The synthesized AAMS-1 was characterized with IR spectrum. Thermogravimetric analysis showed that AAMS-1 was chemically stable at 250℃. The synthesized AAMS-1 emulsion had particle sizes around 2,500 nm, with critical associating concentration of 0.15%. The network structure of AAMS-1 in fracturing fluids can be clearly seen using with an SEM. Fracturing fluids formulated with AAMS-1 have good viscoelasticity, sand carrying capacity, and permeability protection performance. Water solution of 0.6% AAMS-1 sheared at 150℃ and 170 s-1 for 2 h had residue viscosity not less than 50 mPa·s, indicating that AAMS-1 had satisfactory shearing stability and high temperature stability.
