| 摘 要： | 准确计算携液临界流量对采气工程方案编制有很重要意义。根据最新的研究成果,液滴在气流的作用下呈高宽比接近0.9的椭球体。在这种情况下,计算气井携液临界流量需要考虑液滴形变的影响。在分析了前人携液模型和产水气井携液流动机理的基础上,考虑了液滴内部流动对曳力系数的影响,建立了新的气井携液临界流量计算模型。

| 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 coeffic... |
