| 摘 要： | 介绍了一种三元聚合阻垢剂的合成方法，并对其使用条件以及油田使用情况进行了评价。最佳反应条件为：合成反应时间6 h，丙烯酰胺（AM）、丙烯酸（AA）和自制单体PMA的质量比例为75∶10∶15、反应温度70 ℃，引发剂质量分数1.2%。随着环境温度的上升，阻垢率逐渐下降，在环境温度低于65 ℃的时候，阻垢率可以维持在70%以上。当pH值在6～10时，阻垢率可以维持在65%以上。聚合阻垢剂在WC15-1A海管应用中获得了较好的使用效果。

| Abstract: | Synthesis and running performance of a ternary polymer scale inhibitor is introduced. With duration of 6 h，temperature of 70 ℃ and initiator dose of 1.2%，the scale inhibitor was produced with mass ratio of acryl amide (AM)∶acroleic acid (AA)∶monomer PMA of 75∶10∶15. Inhibition rate decreased with increasing environment temperature. Inhibition rate stayed at least 70%，when environment temperature was below 65 ℃. Inhibition rate stayed above 65%，when pH was from 6 to 10. Application in WEN15-1A seal line showed satisfying performance. |
