| Abstract: | Current models for critical sulfur carrying velocity in wellbores often neglect the impact of collision forces, concentration, and the volume fraction of sulfur particles, the model error becomes significant. This paper investigates the migration behavior and critical sulfur carrying velocity under the influence of various factors, including wellbore inclination angle (30°–90°), particle size (74–240 μm), and gas flow rate (30–160 m³/hr), using multiphase pipe flow experimental apparatus with inner diameter of 50 mm and length of 4 m. Based on the force balance principle for single particle, a new model for the critical sulfur carrying velocity in high-sulfur gas wells is established by considering the gravitational force, buoyancy, and drag force acting on the particles. The model incorporates the effects of particle collisions, particle concentration, the volume of particles, and wellbore inclination angle. Sensitivity analysis reveals that the critical sulfur carrying velocity decreases with an increase in sulfur particle mass flow rate, increases with particle diameter, and initially increases and then decreases as the wellbore inclination angle increases. The model was used to predict sulfur deposition locations in gas wells, with results showing yielding a 6.34% error, verifying the high accuracy and reliability of the model. [ABSTRACT FROM AUTHOR] |
