摘要 采用自由基水溶液聚合法,以纳米二氧化硅(nano-SiO2)、丙烯酸(AA)、丙烯酰胺(AM)和2-丙烯酰胺基-2-甲基丙磺酸(AMPS)等单体为主要原料,合成了四元共聚物降滤失剂P(AA-AMPS-AM)/nano-SiO2;采用FTIR法表征了该降滤失剂的组成,并评价了它的降滤失性效果、抗盐、抗钙和抑制性等性能,同时考察了该降滤失剂与其他处理剂的配伍性。实验结果表明,该降滤失剂具有良好的耐温抗盐降滤失性能,同时具有良好的抑制性能;与常用处理剂配伍性好,可在水基钻井液体系中显著降低其高温高压滤失量,所形成的饱和盐水钻井液体系在密度2.37 g/cm3下的高温高压滤失量仅为20.0 mL,满足高温下控制钻井液性能的需求。 Quadripolymer P(AA-AMPS-AM)/nano-SiO2 used as a filtrate reducer was synthesized by free radical aqueous solution polymerization from acrylic acid(AA), acrylamide(AM), 2-acrylamido-2-methyl propane sulfonic acid(AMPS) and nano-silicon dioxide(nano-SiO2), and characterized by means of FTIR. Its performances, such as filtrate reduction, heat resistance, calcium ion tolerance, inhibitive ability and compatibility with other agents, were investigated. The results showed that the synthesized product exhibited the good performances. Its performance of reducing the high temperature and high pressure filtrate volume can be significant in brine-based drilling fluid system. The saturated saltwater drilling fluid showed that the high temperature and high pressure filtrate volume was only 20 mL with the drilling fluid density of 2.37 g/cm3. In conclusion, the synthesized product can meet the demand of controllin~ drilling fluid ProPerties at high temneratnre
