摘　　要：介绍了AMPS/AM/淀粉接枝共聚物的合成方法及其作为降滤失剂在泥浆中的应用性能。该接枝共聚物在泥浆中具有明显的降滤失作用和较强的抗温、抗盐能力。In this paper, the synthesis of 2-aerylamido-2-methylpropancsulfonate/acrylamidc/starch graft copolymcrs is briefly described and the effect of mass ratio of monomers to starch on the filtration controlling ability of the copolymer obtained is invcstigated, the optimum ratio being 3:1—2:1. The preliminary laboratory evaluation shows that the copolymer synthesized as fluid loss controller is effective in fresh water, salt water, saturatcd salt water and highly mineralized water muds, resistant to high temperarures (150℃, 16h) and tolerent to salt and bivalent ions.
