SKW 化学公司的polydrill,一种抗盐和高温稳定的降滤失聚合物是一种新的钻井液添加剂。其化学结构是以一种新的、能在≤204℃:盐饱和的和超高钙、镁离子浓度条件下提供水基钻井液经济有效的降滤失控制的聚合物。Polydrill 可以被单独使用,也可与其它降滤失添加剂如淀粉、CMC、PAC、HECCMHEC 和聚丙烯酰胺、乙烯基丙烯酸酯类的共聚物和褐煤/木质磺酸盐复配使用以 Polydrill from SKW Chemicals, a salt-tolerant and temperature-stable fluid loss polymer, is a new drilling fluid additive. Its chemical structure is based on a novel, cost-effective, fluid loss-controlled polymer that provides water-based drilling fluids at ≤204 ° C: salt-saturated and ultra-high calcium and magnesium ion concentrations. Polydrill can be used alone or in combination with other fluid loss additives such as starch, CMC, PAC, HECCMHEC and polyacrylamide, copolymers of vinyl acrylates and lignite / lignosulfonate
