Abstract:Aiming at the issue of correcting coefficient in gas well critical liquid-carrying rate calculation equation for gas liquid ration greater than 1400m3,on the basis of the liquid drop being flat-shaped in gas well bore and the relationship of drag coefficient and Reynolds number (between 1×103~2.2×105 and 2.2×105~1.0×106),the new critical rate equation for high gas liquid ration gas-carrying in gas well is established by combining classic mechanics.Theoretically,the disagreement on whether or not the theory equation for critical liquid-carrying rate model being increased by 20% is explained.The model is made more perfect and more compatible with field practice.

Key words: gas well, critical liquid-carrying rate, oil pipeline optimization, application, prediction
