【摘要】 将下脚料聚丙烯腈水解,用三甲胺、甲醛进行阳离子化,再用过氧化氢氧化,制得了阳离子度为10 5%的降滤失剂PKC 3。在PKC 3加量为0 5%的情况下可使膨润土基浆的API滤失量较大幅度地降低,抗盐抗污染性能良好,页岩回收率明显高于所评价的其它处理剂,探讨了其作用机理,现场应用表明,效果明显。更多还原

【Abstract】 The fluid loss additive PKC 3 of 10.5% cationic degree was synthesized from the tailings polyacry lonitrile, which was hydrolyzed, changed to a action by trimethylamine and formaldehyde, and oxidated by H 2O 2. When 0.5% PKC 3 was added into the bentouite base mud, the API filtration was decreased greatly. Its salt resistancy and resistance to fouling was better. Shale rate of recovery was apparently higher than other treating agent appraised, and its role mechanism was discussed. The application of the scene indicates its obvious effect.更多还原
