在江汉油田现用的盐水聚合物泥浆中加入高炉水淬矿渣、激活剂ＪＨＪ１及稀释剂ＸＳＪ３，成功地将泥浆转化为固井用的水泥浆。在室内实验中该水泥浆的稠化时间可控制在２－７小时之间，２４小时抗压强度大于３．５ＭＰａ，滤失量小于２００ｍＬ，这些性能指标均能满足现场一般固井施工要求。在广云８井封固技术套管现场施工中使用这种ＭＴＣ水泥浆，施工顺利，固井质量合格。 In Jianghan Oilfield brine polymer slurry used in blast furnace water quenching slag, activator JHJ 1 and diluent XSJ 3, the successful conversion of mud slurry used for cementing. In the laboratory experiment, the thickening time of the cement slurry can be controlled within 2-7 hours, the compressive strength at 24 hours is more than 3.5MPa, and the filtration loss is less than 200mL. These performance indexes can meet the general cementing construction requirements in the field. The MTC grout was used in the construction of the sealing casing of Guangyun 8 well and the construction was smooth and the cementing quality was acceptable.
