ISO 10426-4:2004标准是针对井下水泥浆和发泡水泥浆的制备和测试的标准。该标准适用于在大气压下制备和测试发泡水泥浆,以及在井下使用的水泥浆。该标准规定了制备和测试发泡水泥浆的方法和要求,以确保其在井下使用时的质量和性能。
该标准要求使用符合要求的原材料制备发泡水泥浆。在制备发泡水泥浆时,应根据所需的密度和其他要求,选择适当的水泥、发泡剂和其他添加剂。制备发泡水泥浆时,应按照标准规定的方法进行,以确保其质量和性能符合要求。
该标准还规定了测试发泡水泥浆的方法和要求。测试应在大气压下进行,以模拟井下环境。测试应包括密度、流动性、稳定性、泡沫性能等指标。测试结果应符合标准规定的要求。
该标准的实施可以确保井下水泥浆和发泡水泥浆的质量和性能符合要求,从而保证井下作业的安全和顺利进行。
