| 摘 要： | 采用氧化－还原引发体系合成了２－丙烯酸胺基－２－甲基丙碳酸－丙烯酰胺－醋酸乙烯酯（ＡＭＰＳ／ＡＭ／ＶＡＣ）三元共聚物钻井液降滤失剂，室内研究表明：ＡＭＰＳ／ＡＭ／ＶＡＣ三元共聚钻井液降滤失荆，抗温、抗盐能力强，在淡水钻井液、饱和盐水钻井液和人工海水钻井液中均有较强的降滤失作用。评价了三元共聚物对钻井液性能的影响，选择了合适的配方，探讨了影响三元共聚物降滤失能力的因素和引发剂、ＡＭＰＳ的用量对三元共聚物降滤失性能的影响。

| Abstract: | In this paper, a new filtration reducer-AMPS/AM/VAC copolymer is synthesized by redox innation. The experimental results show that the AMPS/AM/VAC copolmper filtration reducer has advantages, likehigh heat resistance and salt tolerance capability, good filtration control effects in freshwater drilling fluid, saturated brine drilling fluid and synthetic sea water drilling fluid. The paper evaluates the effects of ternary copolymer on drilling fluid property, explores the factors effecting copolymer filtration control capability and initiatingagent. |
