摘要：

To identify the accurate gas volume to carry liquid in horizontal gas well, this paper simulates the gas-liquid two-phase flow in a single pipe on the platform of multiphase pipe flow. Through indoor experiments on gas-liquid two-phase flow, it is confirmed that the inclined section (inclined angle: 45 degrees similar to 60 degrees) is mostly likely to suffer from liquid loading in horizontal gas well. Then, a new critical liquid-carrying model was built after fitting the liquid holdup calculation formula at different inclined angles, considering the actual liquid-carrying phenomenon. The proposed model was proved accurate enough for engineering application through verification by indoor experiments.
