Study on Critical Liquid-Carrying Flow Rate for Gas Well

Abstract

Abstract: The proper determination of minimum critical liquids carrying flow rate for gas wells is significant for gas production engineering planning. The latest experimental research indicated that the liquid droplet is close to ellipsoidal body with depth-width ratio of 0.9. For this reason, the liquid droplet deformation should be taken into consideration in calculation of critical carrying flow rate. This paper analyzes the rationality of previous models, considers the effect of liquid droplet flow on drag coefficient on the basis of liquidcarrying flow mechanism for gas well with water production, and then develops a new critical liquid carrying flow rate model for it.

Key words: gas well, liquid droplet, ellipsoidal body, drag coefficient, critical flow rate
