摘　　要：脉冲中子氧活化测试能探测油、套管内外的水流速度和方向,测试结果不受井内流体粘度、地层大孔道等因素影响,可以较好地解决注聚井、笼统反注井、找窜井注入剖面测试资料符合率偏低的问题。介绍了脉冲中子氧活化测试的原理、结构、主要技术指标以及在河南油田的应用情况,通过和同位素测井进行对比,探讨了脉冲中子氧活化测井的优越性和局限性。As the pulse neutron oxygen activation logging can detect the speed and direction of water both inside and outside of the tubing, the casing and the logging well result is not effected by the fired viscosity and the macropore path formed in the formation in the well, it can promote the logging data quality perfectly obtained from the polymer injection well, and bypath channel well. This article introduces the principle of the pulse neutron oxygen activation logging, the structure of the downhole tool, its specification, and the apphcation in He'nan oilfieht The advantage and disadvantage of the pulse neutron oxygen activation logging well are discussed by means of comparing with the isotope logging.
