摘　　要：综述了近年来抗高温油井水泥降失水剂的研究现状,分为2-丙烯酰胺基-2-甲基丙磺酸(AMPS)聚合物、改性天然高分子以及聚合物与其他处理剂复配体系三大类。将国内外研究降失水剂的具体实例进行对比分析,总结了国内与国外研究存在的差距,展望了该领域的研究重点和发展方向。The recent research status of high temperature fluid loss additives for well cement are reviewed, which include 2- acrylamido- 2 -methylpropane sulfonic acid （AMPS） copolymers, modified natural polymers, and compounded polymers with other additives. The specific examples for studying fluid loss additive of well cement at home and abroad are compared, and then the differences present in the research at home and abroad are summarized. Finally, the emphasis of research and the direction of development in this field are prospected.
