目前,管道输送原油的交接方式有静态计量和动态计量两种。随着企业的发展,原油采购的品种和数量不断增加和变化,给计量管理带来较大难度,静态计量很难适应新的计量形势,动态计量将全面取代静态计量。在动态计量的过程中,如何提高原油采样的准确性、样品化验的准确性以及流量计运行状况对原油损耗的控制尤为关键,有助于找到影响管输损耗的 Currently, the delivery of crude oil pipelines have two kinds of static measurement and dynamic measurement. With the development of enterprises, the variety and quantity of crude oil procurement are constantly increasing and changing, which brings great difficulty to the measurement management. Static measurement is difficult to adapt to the new measurement situation. Dynamic measurement will completely replace the static measurement. In the process of dynamic measurement, how to improve the accuracy of crude oil sampling, the accuracy of sample testing and the operation of flowmeter are particularly crucial to the control of crude oil loss,
