摘　　要：靖边气田部分气井在投产初期或者投产不久后便会产水,如果气井不能够及时排液,则会影响气井的正常生产,严重情况下甚至会导致气井"淹死";而泡沫排水采气是开发产水气井一项重要的增产措施,主要运用动态分析方法,利用气井泡排前后动态综合对比的手段,对不同水气比类型的产水气井进行泡排评价;经研究认为不同水气比类型的产水气井对应的生产特征也不相同,且两者之间能够相互验证;对气井的继续生产有重要指导意义。In Jingbian gas field a part of gas wells have produce water go into operation early, if the liquid loading can not drainage immediately it will affect the normal production of gas well, even it will ＂killed the gas well＂, foam drainage is a good technical for this type of gas well. This article use the method of dynamic analysis, compare the performance of gas well before and after foam drainage. The writer to evaluate the different water/gas ratio （WGR） types of gas wells. It found that different WGR correspondence different production perfor- mance and mutual authentication. This conclusion for continuing production have important significance.
