摘　　要：目前,国内天然气田气井出水问题突出,严重影响了气田的稳产和提高采收率。排水采气是保证出水气田稳产和提高采收率的主体技术,其中,泡沫排水采气由于其设备简单、操作简便和成本低,成为排水采气的主体工艺。泡沫排水采气效果的好坏主要取决于所用起泡剂的种类和性能。从耐高温高矿化度、抗甲醇、抗凝析油和缓蚀等功能出发,介绍了近年来国内排水采气用起泡剂的室内研究及现场应用进展,并对今后排水采气用起泡剂的研究提出建议。At present, the problem of water production from gas wells in domestic natural gas fields was prominent, which seriously affected the stable production and enhanced gas recovery of gas fields.Drainage gas production was the main technology to ensure stable production and enhance gas recovery in water-producing gas field in which foam drainage gas production had become the main technology of drainage gas production because of its simple equipment, simple operation and low cost.The effect of foam drainage gas production mainly depended on the types and properties of foaming agents used.Based on the functions of temperature and salinity tolerance, methanol resistance, condensate resistance and corrosion inhibition, the progress of research and field application of foaming agents for drainage gas production was introduced in China in recent years, and some suggestions for future research of foaming agents were put forward.
