Abstract The current study offers a practical guide for dealing with water influx and liquid loading problems particular to gas wells. Methods and discussions on remedying these problems are supported by real field cases (eight gas wells from Thrace Basin, Turkey) and are extended to wells targeting unconventional resources (coalbed methane, methane hydrates, shale gas). Indications of liquid loading are discussed, critical gas velocity concept is reviewed and deliquification techniques are presented with advantages, drawbacks, limitations, and optimum application conditions. Specific production strategy suggestions are provided and an improved decision tree is suggested for screening the deliquification methods.

常规和非常规气井脱液技术：回顾、现场案例和减轻液体负荷的经验教训

摘要 当前的研究为处理气井特有的水涌和液体加载问题提供了实用指南。解决这些问题的方法和讨论得到了实际现场案例（土耳其色雷斯盆地的八口气井）的支持，并扩展到针对非常规资源（煤层气、甲烷水合物、页岩气）的井。讨论了液体加载的迹象，回顾了临界气体速度概念，并介绍了脱液化技术的优点、缺点、局限性和最佳应用条件。提供了具体的生产策略建议，并提出了改进的决策树来筛选脱液化方法。
