某些学者已经介绍了几种数学方程式来计算临界流动速度 ,这个参量对于维持气井正常生产是必不可少的。应用最广泛的是Turner等人所使用的方程式。然而 ,Turner方程式需要用不同范围内的数据进行经验修正 ,因此 ,它的应用就存在相当大的问题。本文提出一种新方法 ,应用它来计算对于保持气井正常生产非常重要的参数———临界流动速度。这种方法依然采用Turner等人的基本原理 ,但是考虑了不同流动状态下的流动条件。它解释了为何以前Turner方程 (液滴模型 )对于不同范围的数据存在一些偏差 ,并且提出了一组新的方程 ,新方程不必进行经验修正 ,并且能与实际数据记录更好地匹配 Some scholars have introduced several mathematical equations to calculate the critical flow rate, which is necessary to maintain the normal production of gas well. The most widely used is the equation used by Turner et al. However, the Turner equation needs to be empirically corrected with different ranges of data and, therefore, its application poses considerable problems. This paper presents a new method that can be used to calculate the critical flow rate that is important for maintaining normal gas production. This method still adopts the basic principle of Turner et al., But considers the flow conditions under different flow conditions. It explains why the Turner equation (droplet model) has some deviations from different ranges of data in the past and proposes a new set of equations that do not have to be empirically corrected and better matched to actual data records
