摘　　要：目前涩北气田在生产过程中常常伴随着产层出水、井底积液等特点,从而导致产层生产压差的降低,最终使产能的提高受到了严重的影响。因此,迫切需要一套了解各产层出水的动态监测手段。脉冲氧活化测井由于具有测量范围宽、精度高且能够直观测量水流方向与速度等优势,在注水井中已广泛应用。根据脉冲氧活化的测井原理,结合气井产气剖面资料,提出了气井中脉冲氧活化水流时间谱对比分析方法来确定出水层位。通过对涩北气田1口井实测资料处理结果与理论分析对比来看,该方法能够准确找出出水层位。Currently water production was often accompanied in producing layers,fluid was accumulated on bottom hole in Sebei Gas Field,which resulted in lower pressure differential in production and severely influenced ultimate productivity.Therefore a set of monitoring tools were urgently needed to understand dynamic states of water production in each producing zone.Pulse oxygen activated logging had advantages of wide measurement range,high accuracy and could measure the flow direction and speed,it has been widely used in water injection wells.According to its principle and in combination with production data of gas wells.It is proposed that time spectral analysis of pulse oxygen activated water flow is used to determine water producing layers,the result from 3 wells in Sebei Gas Field is compared with that of theoretical analysis,it indicates that the method can be used for accurately finding out water layers.
