井下脉冲中子氧活化类流量测试仪是生产测井过程中进行真实井况复现的专用测井仪器，目前国内外尚无可靠、准确、安全的校准方法。为此，采用了油气水流量综合检定装置与地下模拟实验井衔接的方法解决此类测井仪实流标定问题，同时可进行油田生产测试常规井下流量测试仪器的校准，并在应用中不断改进完善。应用此方法已对 200多套井下流量含水测试仪器及氧活化类流量测井仪器实施了校准，实验表明该方法安全、可靠、有效。

Underground pulse neutron oxygen activation flow measurement is specific logging equipment for actual well condi-tion repeatability and reproducibility during production logging procedure. There is no as yet reliable, accuracy and safety calibration methods at home and aboard at present. According to this situation, adopting oil-gas-water flow comprehensive investigate equipment combining with underground stimulation well to solve the actual flow calibration of this logging wells. Meanwhile, this method could conduct the calibration of underground flow testing equipment for conventional production measurement in oilfield, and be improved continuously during the application. At present, More than 200 sets of underground flow water-bearing test equipment and oxygen activation flow logging equipment were calibrated by this method, and the results prove that the method is safe, reliable and effective.
