It is very important to calculate the critical liquid-carrying flow for gas well.In this paper, an ellipsoid droplet model is established. By analyzing the droplet force in the inclined well and comprehensively considering the droplet drag force, gravity force, friction force, buoyancy force and supporting force, the general formula for calculating the critical liquid carrying flow is obtained. By using the reasonable formula of gas-liquid interfacial tension and The Formula of Weber number, the critical liquid carrying flow of gas well is verified.
