Through the correlationanalysis of Yan qi 2-Yan 128 wellsand the comparison of turner model, Coleman model, Li Min model and Wang Yizhong model, combining the above analysis results, the wellbore with liquid effusion was chose to carry on liquid flux model analysis,and finally the model of Yan qi 2-Yan 128 well was predicted and theaccuracy of the fitting was over 94%. At the same time, the influence of temperature and pipe diameter on the liquid carrying capacity was found out, in the external factors, tubing size had greater impact, carrying liquid volume was proportional to the diameter.%通过对延气2-延128井区气井相关分析，以及对Turner模型、 Colemαn模型、李闽模型和王毅忠模型进行对比，综合以上分析结果，选择有积液现象的井筒进行携液流量模型分析，最终拟合出合适延气2-延128井区气井的模型并进行预测，拟合结果的准确率达到94%以上，同时找出温度和管径对携液量的影响关系，外界因素中主要以油管尺寸影响较大，携液量与管径成正比。
