摘　　要：以马来酸酐(MA)、丙烯酸(AA)、2-丙烯酰胺基-2-甲基丙磺酸(AMPS)等为单体,H2O2-NaH2PO2为引发剂,水为溶剂,在催化剂存在下合成MA/AA/AMPS三元共聚物阻垢分散剂SY-1#,并对其性能进行评价。实验表明,SY-1#阻垢分散剂具有优良性能:耐高温性强,可达100℃;在pH=10时,仍能保持其良好的性能;使用剂量低,浓度为5mg/L时阻碳酸钙垢的阻垢率达到94.0﹪,分散氧化铁能力达到35.5﹪;且其与其它油田助剂具有良好配伍性。A water-soluble MMAMAMPS scale inhibition and dispersion agent SY-I^# was prepared by radical polymerization of maleieanhydride （MAA）, acrylic acid （AA） and 2-aerylamide-2-methylpropanesulfonic acid （AMPS） in aqueous solution using H2O2- NaH2PO2 as initiator, and its performances were evaluated. The experimental results showed that SY-1^# had excellent performances： （1） good thermal stability in below 100℃; （2） good properties even in high pH value of up to 10; （3） high effieieney at low dosage, such as at SY-1^# concentration of 5mg/L, the CaCO3 scale inhibition efficiency up to 94.0 %, and the ferrie oxide dispersion efficien- cy up to 35.5 % ; （4） good compatibility with other oilfield chemicals.
