This article proposes a new model for calculating the gas-well liquid loading capacity,which is critical to an accurate prediction of gas well production.Based on analysis of flow regime during the gas well production with water,which is regarded as many single particles in the model,with the shape of particles being assumed as disk-like ellipsoid instead of traditional sphere and changing according to the forces exerted on them,the influences of non-Darcy flow,compressibility,and non-sphere shape on friction factor are analyzed.The differences between the new model and other models are discussed and a new formula for calculating the critical flow rate is obtained.The calculation results and a comparison with other two models show that the new model is more consistent with the actual situation and is practical.
