摘　　要：合成了丙烯酰胺基乙基二甲基氯化铵/丙烯酰胺/丙烯酸(AEDMAC/AM/AA)共聚物钻井液降滤失剂,评价了此共聚物钻井液性能。结果表明,AEDMAC/AM/AA共聚物具有良好的降滤失、防塌、保护油气层性能,抗温、抗盐污染能力强。The acrylamidoethyldimethylammonium chloride/acrylic acid/acrylamide (AEDMAC/AM/AA) copolymer as drilling fluid filtrate reducer was synthesized. The drilling fluid performances of AEDMAC/AM/AA copolymer were evaluated in laboratory. The results showed that the AEDMAC/AM/AA copolymer has very good depressing filter loss, protection against collapse, reservoir protection, heat resistance and salt tolerance.
