Abstract Field testing data from five different wells using load cell sensors were analysed to investigate their possible application for estimating geothermal two-phase fluid enthalpy. Two different data analysis approaches - measuring the liquid phase velocity and estimating the dryness fraction - were examined. The liquid velocity was predicted successfully using the cross-correlation technique. However, liquid velocity cannot be used alone to measure the fluid enthalpy without slip ratio and void fraction. It was only possible to calculate the dryness fraction estimate from the weight of the pipeline for one data set due to measurement noise and the results were found to be of low quality. The remaining technical challenges and recommendations are discussed.

使用称重传感器实时测量两相地热流体流动的焓：现场测试结果

摘要 使用称重传感器分析了来自五口不同井的现场测试数据，以研究它们在估计地热两相流体焓方面的可能应用。检查了两种不同的数据分析方法——测量液相速度和估计干度分数。使用互相关技术成功地预测了液体速度。然而，不能单独使用液体速度来测量没有滑移率和空隙率的流体焓。由于测量噪声，只能根据管道重量计算一组数据的干燥度估计值，并且发现结果质量低。讨论了剩余的技术挑战和建议。
