油井生产动态数据要求客观、准确。但受矿场计量条件和油、气、水三相混合的影响,计量误差长期难以降低。产生计量误差的主要原因是对油井产液计量过程中伴生气影响原油密度缺少合理处理方法。本文结合油田矿场计量站内两相卧式分离器配套使用板式液位计量油和流量计量油两种计量方式,分析资料问题的原因及误差程度,尝试提出降低计量误差的一些思路。 The dynamic data requirements of oil well production are objective and accurate. However, due to the measurement conditions of mines and the mixture of oil, gas and water, the measurement error can not be reduced for a long time. The main reason for the measurement error is due to the lack of reasonable treatment of the density of the crude oil accompanying the gas during oil well liquid production measurement. In this paper, two measuring methods of plate level measuring oil and flow measuring oil are used in combination with the two-phase horizontal separator in oil field mine metering station to analyze the reason and error degree of data problems and try to put forward some ideas to reduce measuring error.
