原油密度测定的一个重要数据,其测定的准确性,直接影响到贸易双方的利益。文章针对原油水分密度测定时,管线动态取样与油罐内静态取样的差异、实际均样的方法、分样称量及作密度测定的试验温度等进行了分析。
Crude oil density determination of an important data, the determination of the accuracy of a direct impact on the interests of both trade. The paper analyzes the difference between the dynamic sampling of pipeline and the static sampling in oil tank, the actual and the same method, the sub-sample weighing and the test temperature for density determination when measuring the moisture density of crude oil.
