摘要
合成了ＡＭＰＳ／ＡＡ／ＭＡ三元共聚物，研究了合成反应中ＭＡ用量对淡水泥浆、含盐和含钙泥浆及强碱性泥浆性能的影响。研究结果表明，ＭＡ用量为６０％（摩尔）的ＡＭＰＳ／ＡＡ／ＭＡ三元共聚物的抗钙性能明显优于ＡＭＰＳ／ＡＡ二元共聚物；ＭＡ用量为３０％（摩尔）的三元共聚物的抗温抗盐性能与ＡＭＰＳ／ＡＡ二元共聚物相当。
Tow terpolymers of 2 acrylamido 2 methylpropylsulfonic acid (AMPS),acrylic acid (AA) and maleic anhydride (MA) and two coplymers are prepared and their properties in fresh water,salt water and high pH drilling muds are studied experimentally.It is shown that the heat resistance and tolerencies to NaCl and alkali of the terpolymer with molar ratio monomers AMPS/AA/MA=5/65/30 are similar to that of the 5/95 AMPS/AA copolymer and the 5/35/60 terpolymer has a notable advantage over the AMPS/AA copolymers,5/95 and with higher AMPS contents, in the calcium tolerence of the muds.
