摘　　要：以丙烯酰胺、甲醛、亚硫酸氢钠为原料,合成了阴离子单体磺甲基丙烯酰胺(SMAM)。再以丙烯酰胺(AM)、阳离子单体 HMC-1、磺甲基丙烯酰胺为原料,合成了 AM/HMC-1/SMAM三元共聚物降失水剂。研究了单体配比、引发剂加量、反应温度对产品性能的影响,确定了该降失水剂最佳合成条件:阳离子度30%,阴离子度60%,反应温度60℃,过硫酸铵引发剂加量0.3%。结果表明,加入该降失水剂后,泥浆失水量明显降低,而且泥浆具有较好的流变性。An anion monomer sulfomethyl acrylamide （SMAM） was synthesized with acrylamide, formaldehyde, and sodium bisulfite as raw materials. A terpolymer fluid loss additive AM/HMC - 1/SMAM was further synthesized using acrylamide（ AM）, cation monomer HMC - 1, and SMAM as materials. The effects of the ratio of monomers, amount of initiator, and reaction temperature on the product performances were investigated. The optimum synthetic condition was as follows： cation degree 30%, anion degree 60%, reaction temperature 60℃, and initiator ammonium persulfate 0.3%. The research result showed that water loss of mud was decreased greatly and the mud possessed good rheological property after adding the terpolymer fluid loss reducer.
