| 摘 要： | 以2-丙烯酰胺基-2-甲基丙磺酸（AMPS）和丙烯酰胺（AM）为原料，合成了油井水泥浆降失水剂AM／AMPS共聚物。确定了AM／AMPS共聚物降失水剂的最佳合成条件：单体加量8％，AMPS与AM质量比1：7，引发剂加量0．5％，反应体系pH值7，反应温度50℃。该共聚物降失水剂能有效控制水泥浆的失水量，且保证水泥浆的其他性能在一定范围内可调。

| Abstract: | An AM/AMPS copolymer as oil - well cement slurry fluid loss additive was synthesized using 2 - acry- lamido- 2- methylpropanesulfonic acid （AMPS） and acrylamide （AM） as materials. The optimal synthetic condition was determined as follows ： monomer 8 %, mass ratio of AMPS/AM 1 ： 7, initiator 0.5 %, pH 7, and reaction temperature 50 ℃. The copolymer fluid loss additive could control cement slurry filtrate effectively and had no effect on other properties of cement slurry. |
