中哈原油管道在计量交接过程中,由于分别使用了俄罗斯ГОСТ标准规定的原油油量计量方法和中国国家标准规定的原油油量计量方法,因此导致交接油量的计算结果不同。介绍了2种计量方法进行原油静态计量和原油动态计量的计算公式,比较了2种计量方法存在的主要差异:ГОСТ标准计算油量为原油在真空中的净质量,而中国国标计算的油量为原油在空气中的净质量;ГОСТ标准计算油量时减去了原油中水、氯盐及机械杂质的含量,而中国国标计算油量时只减去原油中的水含量。对ГОСТ标准的计算油量乘以空气浮力系数0.9987进行修正,即与中国国标的计算油量基本一致。
During the process of metrological handover, the crude oil pipelines of China and Kazakhstan, as a result of using the crude oil measurement method stipulated by the Russian ГОСТ standard and the crude oil measurement method stipulated by China’s national standard respectively, resulted in different calculation results of the delivered oil volume. Two kinds of measurement methods are introduced to calculate the static measurement of crude oil and the dynamic measurement of crude oil. The main differences between the two measurement methods are compared: ГОСТ standard calculates the net mass of crude oil in vacuum, while the calculated value of China national standard The net mass of crude oil in the air; ГОСТ standard when calculating the amount of oil minus the crude oil in water, chloride and mechanical impurities content, while China GB only calculates the amount of oil minus the water content of crude oil. The calculation of ГОСТ standard fuel multiplied by the air buoyancy coefficient of 0.9987 to be amended, that is, with the Chinese national standard calculation of oil is basically the same.
