摘要
介绍了油井三相分离计量装置的结构、工作原理、技术参数以及所使用的计量仪表,并根据误差理论,计算了该装置的计量准确度。计算结果表明,纯油的计量准确度为±4.7％,水的计量准确度为±3.7％,气的计量准确度为±10.4％,完全达到了中国石油天然气总公司对油井计量准确度的要求。
This article introduces the structure, working principle, tcchnical paramters, metering instrument used and base on error theory calculats its metering accuracy. Calculation result indicats that the accuracy for pure oil is ±4.7％, for water±3.7％, for gas±10.4％. they all attains the requirement of oil well metering of CNPC.
