Turbine Flowmeter Models for Measuring Oil-Gas-Water Three Phase Flow in Vertical Upward Pipes

摘要

Based on the experimental data obtained by the Annulus Three Phase Flow Tool worked in vertical oil-gas-water three phase flow, we investigated the applicability of existing turbine meter models. In model evaluations, we consider the effects of three phase flow characteristics, such as slip ratio, the gas phase distribution, the gas drift flux velocity. The results show that the momentum model of turbine meter has a good prediction accuracy of total flow rate, and gives a more reasonable physical interpretation. The corrected volumetric model of turbine meter gives a high prediction accuracy of total flow rate, but the applicability beyond the current experimental data is still unclear, and we need to perform the more model test in future within wide range flow conditions.
