摘要
简要介绍了AA/MA/MMA三元共聚物钠盐(防垢剂HFG-1)的合成,报导了该防垢剂的室内性能评价结果。HFG-1无毒,不污染环境,防垢效力高,能耐温耐高pH值。
An acrylic acid/maleic anhydride/methylmethacrylate terpolymer in sodium salt form is prepared as scalc inhibitor (HFG-1) for treating produced waters in oil fields are tested in laboratory for determining its clouding pH point in high Ca^(2+) media (pH 11.2, 10.5 and 6.4 at ca^(2+) concentration 4000,5000,7000ppm,respectively), heat resistance at 70℃ and 180℃, and use level in various waters at different temperatures (from 1.2ppm for CaSO_4 precipitation control at 70℃ to several hundred ppm for controlling mixed salfs precipitation at 180℃). The composition and molecular mass of terpolymer is also discussed.
