温度和压力对原油动态计量标准体积的影响

一般大型油田原油外销计量具有连续运行、动态计量、数量大、精度高的特点.在密闭压力管道中,计量温度和压力直接影响原油标准体积的计算结果,进而影响纯油量结算,事关原油交接双方的经济利益,尤其在大型原油交接点,由于交接量较大,更应引起足够的重视.

Influence of Temperature and Pressure on Dynamic Metering of Standard Volume of Crude Oil

The custody transfer metering in large-scale oilfield is generally characterized by continuous metering, huge volume and high accuracy. In tight and pressured pipeline,the metering temperature and pressure will directly impact the metering results for the standard volume of crude oil,which influences the net volume's settlement and involves in the profits of the two parties. The authors consider that the influence of temperature and pressure to the metering of standard volume of crude oil should be emphasized because of huge volume,especially in large-scale crude oil custody transfer station.
