Abstract A reservoir wellbore model that couples pressure drop and flow rate is developed based on a homogeneous model for a gas–liquid two‐phase flow in a perforated vertical well. The perforation pressure drop, liquid holdup, and inflow along the depth of the perforated vertical well are studied. The total pressure drop in a perforated vertical wellbore is made up of acceleration, wall friction, and gravity pressure drop. The model is applied to a high‐pressure, high‐temperature infinite and finite conductivity gas well, and an iterative scheme is employed to solve the coupling mode.
