摘　　要：介绍了AM／AA／MPTMA／淀粉接技共聚物泥浆降滤失剂的合成方法，探讨了合成条件对接枝共聚物降滤失能力的影响，并对其性能进行了室内初步评价。结果表明，AM／AA／MPTMA／淀粉接枝共聚物具有较好的降滤失、抗温、抗盐和抗钙、镁污染的能力。The synthesis of the AM/AA/MPTMA/Starch graft copolymer filtration reducer for mud was described. The dependence of the mud properties of the AM/AA/MPTMA/Starch graft copolymer on synthesis conditions was investigated. The mud properties of the AM/AA/MPTMA/Starch graft copolymer was evaluated in laboratory. The experimental results showed that the AM/AA/ MPTMA/Starch graft copolymer filtration reducer was a pretty good in the capacites of depressing the filter loss. Thermal stability, resistance to salt, calcium and magenesiumion.
