摘　　要：利用2-丙烯酰胺-2-甲基丙磺酸(AMPS)与含不饱和键的多元羧酸进行共聚反应,研制了一种新型抗高温缓凝剂HTR-200C.采用FT-IR、DSC和TG等研究方法考察了共聚物的结构和耐温性能,还同时考察了HTR-200C的高温缓凝性能、对水泥石抗压强度发展的影响以及其配伍性能,并探讨了HTR-200C的缓凝机理.研究结果表明,新型缓凝剂HTR-200C可抗180,℃高温,稠化时间具有良好的线性可调性,过渡时间短,与其他油井外加剂也有很好的配伍性,稠化曲线能够满足要求.A new retarder is synthesized with 2-acrylamido-2-methylpropane sulfonic acid （AMPS） and organic poly-carboxylic acid. The structure and thermal stability of the copolymer was characterized with FT-IR, DSC and TG. And the high temperature retardation, compatibility with other cement additives and the effects of those properties on compressive strength of cement were evaluated. In addition, HTR-200C retarded mechanism was analyzed. The re- suits demonstrate that HTR-200C can be used at 180℃ with excellent retardation, controllable thickening time, ideal thickening curve and short transient time on thickening curve. There is no effect on compressive strength, and good compatibility with other additives is possible.
