摘　　要：脉冲中子氧活化测井技术目前广泛应用于油田注入剖面的监测。传统解释方法是根据源距和渡越时间来估算相应的水流速度,这种方法会因为计算渡越时间带来的误差而影响流量计算的精确性,为此,基于脉冲中子氧活化测井的物理测量原理,提出了一种定量解释注入剖面的最优化解释方法。在实例分析部分,采用最优化解释方法对多个注水井进行解释,结果表明采用最优化解释方法能直接测量出测点水流速度,并且计算出的层位流量值具有较高的准确性,提高了注入剖面解释精度。Pulsed neutron oxygen activation logging technology is widely used in oil field injection profile monitoring.Traditional interpretation method is based on the source distance and transit time to estimate the corresponding flow speed,this method for computing the error and the effects of transit time flow calculation accuracy,therefore,based on the physical measurement principle of pulsed neutron oxygen activation logging,this paper proposes a quantitative interpretation method of injection profile optimization.In the example analysis part,the optimization interpretation method is used to explain several injection wells.The results show that the optimization interpretation method can directly measure the water velocity at the measuring point,and the calculated zone flow value has high accuracy,which improves the interpretation accuracy of injection profile.
