|
摘要
为了解决200℃以上超高温固井降失水问题,以2-丙烯酰胺基-2-甲基丙磺酸(AMPS)、丙烯酰胺(AM)、丙烯酸(AA)和腐殖酸钠为原料,合成了一种超高温固井用降失水剂。通过水泥浆性能评价,发现其在超高温条件下有较强的控制失水能力,添加有该产品的水泥浆稠化时间可调、抗压强度发展迅速,与不同的水泥浆体系配伍性好,是一种综合性能优良的产品。
In order to solve cementing fluid loss problem with ultra-high temperature above200 ℃, an ultra-high temperature fluid loss additive was synthesized with 2-acrylamide-2-methyl propane sulfonic acid(AMPS), acrylamide(AM), acrylic acid(AA) and sodium humic acid as raw material. By cement slurry performance evaluation, it has shown comprehensively excellent performance in respect of strong ability of fluid loss controlling in the ultrahigh temperature, with adjustable thickening time, rapid development of compressive strength,and good compatibility with different cement slurry system.
