摘　　要：氧活化水流测井是一种测量井下水流速度的测井方法。它解决了常规测井仪器在高粘、出砂、大孔道和管外窜槽等某些特殊注入井中无法准确测量水流速度的难题。介绍了氧活化水流测井仪器结构、测井原理和特点。大港油田生产测井应用实例表明,对存在井下同位素注入剖面严重污染井、油套分注井、大孔道注水井、注聚合物井、管外窜槽检查等有良好适用性。Oxygen Activation Water Flow Logging is a method of measuring the velocity of fluid in downhole. It resolves the difficulty that conventional production logging tool cannot measure the fluid velocity accurately in some injection wells with unique environments such as high viscosity, sand production, large tunnels and channel behind casing. This paper introduces the structure, principles, and properties of Oxygen Activation Flow Tool. Field applications in production well logging in Dagang Oilfield show that Oxygen Activation Water Flow Logging is applicable in injection wells with serious isotope pollution, injection through tubing and casing, existence of large channels, polymer injection, as well as in the inspection of channel outside casing. It will play a more effective role in injection profile monitoring.
