A New Model of Critical Liquid Carrying in Gas Wells

Abstract:

Based on the Turner’s liquid-loading model for gas wells, combined with Liquid Membrane Breaking Theory and Law of energy Conservation, a new liquid-loading model for mist flow in wave shaped crushing mode for gas-liquid wells was put forward, and a new equation for critical liquid-loading gas flow rate estimation was derived. The results show that the lowest conditions for liquid loading is that most of liquid drops can continuously move upward in gas flow, and when radii of liquid drops are smaller than 1600μm, liquid drops in the wellbore are basically in spherical shape. The critical liquid-carrying gas flow rate, in gas wells, calculated with this new model, is more reasonable and accurate.
