摘　　要：文章介绍了38mm双向水流氧活化测井仪的结构、工作方式和特点,可一次下井测量不同方向水流的速度。在结构设计中采用一个中子发生器、两组伽马探测器,通过稳定的采集与控制系统完成时序控制过程。现场试验和测井评价表明,该仪器稳定性好,测井效率高,有利于在分层配注井和注聚合物井中使用。This paper introduces the structure, work mode and features of 38 mm two-way flow oxygen activation logging instrument. This instrument can measure the speed by different direction flow in once time. In the structural design one neutron generator,two groups of gamma probe are adopted,timing control process accomplishes by the stable acquisition and control system. Field test and logging evaluation show that the instrument has good stability, high logging efficiency, and will benefit separate layer injection allocation well and note polymer well.
