取样方法对测定管输原油含水率的影响

The Influence of Sampling Methods on the Determination of Water Content in Pipeline Oil Crude

从理论上建立和分析管输原油实际含水率与采样获取的含水率的数学模型,通过不同的采样方式对数学模型进行验证。从理论和实践两个方面对流量比例样和时间比例样进行了对比,指出流量比例样的含水率更接近实际含水率。

The mathematical model about practical water content of pipeline oil crude and water cut obtained by sampling is estab- fished and analyzed from theory, and then it is verified by different sampling methods, At the same time, the contrast between the proportional samples of flow rate and time has been conducted from two aspects of theory and practice, showing that water cut in the proportional sample of flow rate is close to the practical water content.
