在顺丁烯二酸酐(MA)、丙烯酸(AA)、丙烯酸甲酯(MAc)共聚时加入链转移剂(巯基醋酸)和第四单体(醋酸乙烯酯、甲基丙烯酸),共聚物的阻垢效果有所增加。讨论了 MA-AA-MAc 共聚物对 BaSO4的阻垢率与溶液温度和 Ba~(2+)浓度等的关系.研究了 MA-AA-MAc 共聚物与有机膦酸复配的协同效应。MA-AA-MAc 共聚物与乙二胺四甲叉膦酸复配使用时增效作用显著,经合成水和油田矿化水评定,阻止 BaSO_4垢生成的效果较好。
In the maleic anhydride (MA), acrylic acid (AA), methyl acrylate (MAc) was added when the chain transfer agent (mercaptoacetic acid) and the fourth monomer (vinyl acetate, methacrylic acid), the copolymer resistance Scale effect has increased. The relationship between the inhibition rate of BaSO4 by MA-AA-MAc copolymer and the solution temperature and Ba 2+ concentration was discussed.The synergistic effect of MA-AA-MAc copolymer and organic phosphonic acid was studied. MA-AA-MAc copolymer and ethylenediamine tetramethylene phosphonic acid synergistic effect when used in combination significantly, synthetic water and oil mineralized water assessment to prevent BaSO_4 scale production is better.
