What is more, the slurry with GH-9 in has very short transient time in thickening test.
为解决深井及超深井固井难题,克服一般固井用缓凝剂材料(铁铬盐、酒石酸、CMHEC、木质素磺酸盐等)存在的过缓凝或过敏感、不抗高温的弊病,研制开发了GH-9油井水泥抗高温缓凝剂,该高温缓凝剂是用一种不饱和二元有机酸衣康酸(又称亚甲基丁二酸)和另外一种带有磺酸基团的乙烯单体AMPS(又称2-丙烯酰胺-2-甲基丙磺酸)在引发条件下聚合反应制成,该产品有很好的高温缓凝作用,与大多数的分散剂、降失水剂有良好的相容性,配制的水泥浆具有高温直角稠化的特点。
