| 摘 要： | 油气两相流流量测试技术一直是油田两相流研究的重要领域,对油井产能评估和油田的现场管理意义重大.但由于缺乏高精度的测量装置以及气液间滑速比的存在,一直很难获得高精度的两相流的相流量.今利用文丘里管和空泡份额传感器对油气两相流流量测试方法进行了理论和实验研究,首先采用辐射式的空泡份额传感器对流动管道的截面含气率进行了测量,进而计算得到混合物的密度;然后利用喉径比为0.45的经典文丘里管测量得到了两相流总质量流量.在此基础上,考虑了油、气两相界面滑速比对气相流量计算产生的影响,改进了传统的均相流模型,得到了气液两相流气相流量新的计算方法.实验结果表明,利用该方法计算得到的油气两相流总流量、液相流量以及气相流量都具有较高的精度,能够满足现场测试要求,从而为现场测量提供了一种新的计算方法.

| Abstract: | In petroleum industry, how to measure the flowrate of oil-gas two-phase flow accurately is important for the evaluation of the well production and the management of the oilfield. Because of the complicatedness of the slip between the gas phase and the liquid phase and the lack of high-accuracy two-phase measuring appliance, it is difficult to obtain the accurate two-phase flowrate. Theoretical and experimental investigations of the two-phase flowrate measurement were carried out in an oil-gas two-phase expe... |
