摘要
按照原油产量进站方式不同,以及计量工作的先后顺序,指出在联合站内原油交接计量时产生误差的环节有:管输进站原油表计量误差;拉油车进站时原油称重误差;原油取样不当误差;化验原油水值过程中产生的误差;盘库产量核实进站产量时产生的误差。误差主要为两大类,一类为仪器自身误差,一类为人为操作误差。
According to the different modes in which crude oil enters the unitised station and the operating procedure for measurement, the errors that occur in the process of custody transfer metering include error in metering pipeline oil, error in weighing crude oil carried by tank cars, error caused by improper sampling, error in testing water content, and error in verifying oil inventory. These errors fall into two types: one caused by instruments and the other caused by human operation.
