摘要
研究了大庆油田第四采油厂用清水配制的带支链的部分水解聚丙烯酰胺(HPAM)溶液,在模拟地层温度下的流变性特点.结果表明,相同质量浓度的黏度平均相对分子质量(Mr)相近的聚合物溶液中,带有较多支链的黏度较高;动态震荡剪切试验中,带有较多支链的聚合物水溶液弹性较大.
Rheological property of the aqueous solution, which was made of branched partly hydrolyzed polyacrylamide and water from Daqing Oilfield, was studied at 45 ℃ with HAAKE rheometer. The results showed that when polymers with similar molecular weights were studied, solutions of those with more branches showed higher viscosity. Viscoelasticity of the solution of branched polyacrylamide and that of commercial samples were also measured and compared.
