摘　　要：针对郑411-P7井进行基本物性测定,通过可编程式流变仪开展流变性实验研究,探讨了含水率、温度、剪切速率对流变性的影响。结果表明,含水率是影响含水超特稠油流变性的重要因素,随含水率的变化,含水超特稠油的表观粘度呈现出比较复杂的规律。油样含水率大于30%之后,非牛顿性已不明显。在较高含水率下流变性还受温度和剪切速率的影响,不同情况下有不同的流型转化点。Through measuring the basic physical properties and model Dv-111＋programmable rheometer,the experimental research on rheological properties was done,which analysed the influence of water content ratio,temperature and shear rate.The results show that the rate of water content is a major factor that influences rheological characteristies of water-bearing super-heavy oil.With the change of water content ratio,the apparent viscosity of super heavy oil exhibits a more complex pattern.Oil water ratio greater than 30%,the non Newtonian character is not obvious when the rate of water content was over 30%.What＇s more,the temperature and shear rate have an influence on the rheological property when the rate of water content was high.Different conditions have different flow pattern transition point.
