摘　　要：固井用水泥外加剂是指在固井作业中,为保证施工顺利进行和固井质量,在水泥中所添加的化学药剂,笔者主要介绍了国内外固井外加剂的研究现状,包括促凝剂、缓凝剂、消泡剂、减阻剂、降滤失剂、减轻剂、防漏剂、加重剂,对各种方法进行了评价和比较,并对今后固井用水泥外加剂的研究提出了建议。Cementing admixture is a chemical added in cement in order to ensure the smooth progress of construction and cementing quality. In this paper, several additives at home and abroad were introduced, including coagulants, retarders, defoamers, DRA, fluid loss additives, reducing agents, caulks, weighting agents. And some suggestions about the future research on the additives were presented.
