摘要
以丙烯酰胺(AM)、2-丙烯酰胺-2-甲基丙磺酸(AMPS)和甲基丙烯酸十八酯为单体,过硫酸钾(K2S2O8)-亚硫酸氢钠(NaHSO3)为氧化还原引发体系,Span60为乳化剂、煤油为分散相进行反相微乳液聚合,合成了驱油用耐温抗盐聚合物。研究了单体的加量、单体的浓度、引发剂的浓度、反应温度、pH值等因素对聚合物粘度的影响,并对产品的耐温抗盐性进行评价。结果表明:在AMPS加量为20%、甲基丙烯酸十八酯加量为1%、单体的浓度为25%、反应温度为53℃、引发剂浓度为0.4%、pH值为10、反应7～8h时,聚合物的粘度最大,并表现出良好的耐温抗盐性能。
A temperature and salt resistance of polymer flooding was prepared from the materials of AM （acrylamide）,AMPS（2-acrylamide-2-methylpropane sulfonic acid）,methyl octadecyl acrylate as monomers,the redox system was K2S2Os（potassium persulfate）- NaHSO3 sodium bisulfit~,Span60 as emulsifier by Reverse microemulsion synthesis~ in kerosene and water. To studied increase the volume of monomer monomer concentration, initiator con- centration, reaction temperature,pH of such factors on the impact of the Polymer viscosity,and evaluation its tem- perature and salt resistance. The results showed that： AMPS amount as 20%,methyl octadecyl acrylate amount as 1%,the concentration of monomer was 25%, reaction temperature was 53 ~C,initiator concentration of 0.4%, pH = 10, reaction time was 7 - 8h. It has the largest viscosity of the polymer and demonstrate good of the temperature and salt resistance.
