The Synthesis and Application of Temperature Sensitivity Resistance Retarder Suitable for Big Temperature Difference Environment

  • 摘要: 规律的水泥浆稠化时间是保证固井作业安全进行的前提,稠化时间异常会对固井施工带来严重的影响。波特兰水泥在100~120℃范围内,水泥水化会产生变化,水泥浆的稠化时间通常规律性较差,存在稠化反转或缓凝剂失效现象,给现场固井作业带来一定的安全隐患。研究了一种新型聚合物缓凝剂CCH120,并在室内对使用CCH120的抗温敏大温差水泥浆体系和现有的水泥浆体系进行对比。研究结果表明,100~120℃中温水泥浆敏感段,CCH120聚合物水泥浆随温度升高稠化时间逐渐缩短,不存在稠化反转现象,并从机理上进行了解释。该水泥浆体系具有抗温敏性、稠化时间规律性强,失水量低、养护强度高,顶部起强度快的特点。
