摘　　要：氧活化测井解释的关键是确定各测点的水流速度。氧活化测量包括连续测量和脉冲测量两种模式。连续测量的水流速度是通过不同源距探测器计数率的比值来确定。脉冲氧活化水流速度测井解释的关键是准确求解时间谱上水流信号的峰位。该研究简要讨论了氧活化测井的测量模型,初步探讨了聚合物配注井的解释模型,并运用聚合物配注井解释模型处理了某井实测资料,经初步评价,该方法取得的效果良好。The key of oxygen activation logging interpretation was water-flow velocity which determined every measuring point.Oxygen activation measurement included continuous and pulse measurement patterns.Water-flow velocity of continuous measurement was determined by the ratio of count rate value of different source spacing detectors.One of the important steps concerning data interpretation of impulse oxygen activation water-flow logging was to accurately locate the peak position in the time spectrum.Oxygen activation logging measurement models and interpretation models are illustrated,the interpretation models of polymeric compound injection allocation well are used for processing the actual logging data in a well,the preliminary evaluation shows that favorable effect is obtained.
