| 摘 要： | 用标准方法《石油产品运动粘度测定法和动力粘度粘度计算法》（GB/T265—88）检测文昌油田原油运动粘度，应用测量不确定度评定理论，分析了此方法不确定度的重要来源，计算得出本方法的相对不确定度，U（P=99.7%）=3．5％。结果显示文昌油田运动粘度的主要来源于测试温度波动引起试样粘度变化而产生的不确定度，同时粘度计常数和仪器测试时间所引起的相对不确定度对总不确定度也有重要的影响。

| Abstract: | In detection of kinematic viscosity of crude oil in Wenchang oil field based on national standard Petroleum products-Determination of kinematic viscosity and calcution of dynamic viscosity(GB/T 265-88),the reference to the theory of uncertainty determination was made.The relative uncertainty of the primary causation was researched.The relative uncertainty of kinematic viscosity of the crude oil was U(P=99.7 %)was 3.5 %.The result explained that the relative uncertainty caused by temperature fluctuation was ... |
