摘　　要：柴达木盆地的涩北气田出水机理复杂、水源多样,开发过程中气井出水问题对生产影响严重,准确判断出水水源和出水层位对气井出水的防治工作至关重要。生产指标曲线是地下气水流动的直观反映,按照气井日产水量及水气比曲线的变化趋势将气藏出水类型划分为持续较低、由低升高、持续较高和先升后降4种类型,并分析各种产水类型对应的水源。Located in Gaidam Basin,with a complex water production mechanism and diversiform water sources,Sebei gas field encountered a big water breakthrough problem which seriously impacts well productivity,so accurately judging the type of water and the formation is essential to prevention and control work in the gas well. Production index curve is the intuitively reflection of the flowing of underground gas and water. According to the trend of the water production date from well production index curve and water gas ratio curve,four forms of water production curve types are summarized： persistent low,rise form from low to high,persistent high,decline after rise;then an analysis work of all four kinds of curves＇ corresponding types of water source was done.
