从井筒积液形成的机理出发，分析井筒积液的来源，比较几种常用的井简积液预判方法。在对气井井筒压力分布与井筒积液关系分析的基础上，分别给出高、低气液比气井的积液预判数学模型以及在油套连通、不连通两种情况下的井筒积液高度计算方法，并据此进行实例计算。实际运用表明，该方法的计算结果可靠，具有很强的实用性。

In the paper, the formation mechanism of liquid loading and the source of the liquid loading in bore hole are analyzed. Several common methods to judge the liquid loading were summed and compared; the mathematical model to judge the liquid loading related to high gas/liquid ratio and low gas/liquid ratio was respectively proposed; the formula for calculating the height of liquid loading in gas well was given. The case study indicates that the calculated result by this method is reliable and practicable.
