摘要 以对氨基苯磺酸(C6H7NO3S)、对甲基苯磺酸(C7H8O3S)、苯酚(C6H6O)及甲醛(CH2O)为原料,四元共聚合成了降滤失剂AMPF。通过单因素实验法得到最佳合成条件为:pH=9、n(C6H7NO3S)∶n(C7H8O3S)∶n(C6H6O)∶n(CH2O)=1∶4∶6∶13.2,反应温度为75℃。红外光谱图及核磁共振波谱图确证了该降滤失剂的结构;热重分析表征,该四元聚合物具有较好的热稳定性。性能评价表明,合成的四元聚合物具有较好的抗温能力(170℃)和抗盐能力,与其他钻井液常用的处理剂配伍性良好。 Quadripolymer AMPF was benzenesulfonic acid ( C7 H803 S ) , phenol synthesized from sulfanilic acid (C6H7N03S), p-methyl (C6H60) and formaldehyde (CH20). The optimal reaction conditions were determined by adopting the single factor analysis method:the optimal pH synthesis condition of product is 9 ;molar ratio of monomer n( C6HTN03S) :rt( C7H803S) :n( C6H60) :rt( CH20) is 1:4:6:13.2;and the reaction temperature is 75 ℃. Meanwhile, the structure of this reducer is confirmed through infra-red spectrum and I HNMR spectrum, and the results show that the molecular structure of the artificial synthesis product is in accord with the ideal one. The thermogravimetric experiment indicates good thermal stability of this reducer. Moreover, this polymer has demonstrated good temperature resistance, salt tolerance and excellent compatibility.
