摘　　要：脉冲中子氧活化测井是一种能测定井下水流速度的方法,在注入剖面的测试中测得的是分小层绝对注入量。适用于地面油套分注井、井下偏心配水器分注井、存在大孔道地层的井及注聚合物井的注入剖面测试,还可以用于油、水井的查窜找漏。因此,脉冲中子氧活化测井技术在油田注入剖面监测及油、水井查窜、找漏等工作中将发挥越来越重要的作用。Pulse neutron oxygen activation log is a way to measure the speed of water flowing downhole.In the injection profile logging,it can determine the absolute injection rate of every small layers.It is used in the tubing and casing injection water wells on surface,the side-pocket injection allocator water injection wells,the wells with high-capacity channel layers or the wells injected with polymers.And it also can be used in leak detection or channeling detection in oil or water wells.So the technology of pulse neutron oxygen activation logging play a more and more important role in the inspection of oilfield injection profile and the leak detection or channeling detection in oil or water wells.
