摘　　要：为解决深井和超深井固井难题,克服一般缓凝剂材料不耐高温或过敏感等问题,将2-丙烯酰胺基-2-甲基丙磺酸(AMPS)和2种不饱和羧酸单体在加入引发剂条件下进行聚合反应制得高温缓凝剂PC—H42L。研究结果表明,PC-H42L适应温度范围广,抗高温能力强;PC—H42L对水泥浆的沉降稳定性、失水性能和抗压强度无不良影响;加入PC-H42L的水泥浆稠度稳定,且具有良好的防窜性能。To solve the problem of deep and ultra deep well cementing,and overcome the problems of bad thermostability or sensibility of common retarder,the polymers of 2-acrylamide-2-methyl propanesulfonic acid(AMPS) and two kinds of unsaturated carboxylic acids are synthesized with initiator,which obtaines the high temperature retarder PC-H42L.It can be used in a wide temperature range,and has a high thermostability.The cement slurry with PC-H42L has short thickening transition time and good regularity.
