摘　　要：以对苯乙烯磺酸钠(SSS)、丙烯酸(AA)和顺丁烯二酸酐(MA)为主要反应单体,采用水溶液聚合法合成一种三元聚合物,质量分数约为30%,再向其加入5%的羟基乙叉二磷酸(HEDP),混合后得到一种固井用缓凝剂XCT600。通过在水泥浆中评价发现,该产品抗温能力强,在160℃条件下对水泥缓凝作用较强,加量与水泥稠化时间呈线性关系,为高温深井固井作业安全提供了保障。With sodium styrenesulfonate(SSS),acrylic acid(AA)and maleic anhydride(MA)as the main reaction monomers,a ternary polymer with mass fraction of about 30%was synthesized by aqueous solution polymerization,and 5%hydroxyethylidenediphosphoric acid(HEDP)was added to it,after mixing,a set retarder XCT600 for well cementing was obtained.Through evaluation in cement slurry,it was found that the product had strong temperature resistance,strong retarding effect on cement at 160,and ha℃d a linear relationship between dosage and cement thickening time,guaranteeing the safety of high temperature deep well cementing operation.
