摘　　要：评价了以丙烯酰胺为主剂、甲醛为交联剂、过硫酸铵为引发剂,辅以热稳定剂、增强剂等制得的抗盐性预交联凝胶调剖剂RY的性能。结果表明,该抗盐性凝胶调剖剂在自来水中膨胀度可达200倍左右,在1 000-10 000 mg／L盐水中膨胀度仍可达到40-60倍;在95℃环境中放置3个月后性能良好;在原油中收缩率可达90％,起堵水不堵油作用。另外,其柔顺性好,变形能力强,注入性能优良,调剖效果显著,达到提高采收率的目的。Precrosslinked gel profile control agent RY was synthesized from acrylamide as main raw material with ammonium persulfate as initator,formaldehyde as crosslinking agent with heat stabilizer added as aids.The product prepared was evaluated. The result showed this gel profile control agent RY could swell 200 times in fresh water and 40-60 times in salt brine with salt concentration of 1 000-10 000 mg/L.It could keep its swellability at 95 ℃ for 3 months and greatly shrink in crude oil, thus met the requirements of plugging water not oil. In addition, RY behaved well in pliability, deformability as well as in injection. It was effective in controlling profile and could increase the efficiency of recovery.
