摘　　要：究了丙烯酰胺（ＡＭ）和烯丙基磺酸钠（ＡＳＡ）二元共聚物（ＡＳ－１）的合成方法及在油井水泥浆中的降失水作用。实验结果表明，通过引入磺酸基团（－ＳＯ３Ｈ）使ＡＳ－１具有好的抗盐、抗钙性能，是一种良好的降失水剂。The synthesis and functions of a novel antisalt fluid loss additive, AS-1, are reported in this paper. Experimental results indicate that AS-1 exhibits excellent salt tolerance and fluid loss characters, and is compatible with other additives used in cementing.
