摘　　要：为了解决现有氧活化水流测井仪源距固定、仪器可靠性差、故障率高等问题,设计了新型氧活化水流测井仪。新型氧活化水流测井仪通过能力强、适应性好。仪器最多支持13个探头,探头可自由组合,拓展了流速测量范围。通过增大近源距探头晶体尺寸,增加了探头灵敏度,增强了仪器对低速水流的响应。采集时间谱中水流峰清晰,提高了测井资料质量,降低解释难度。同时结合现场作业需求,设计生产测井仪器转换短节可将氧活化水流测井仪与生产测井仪器组合测井,在测量产出剖面的同时实现找水。In order to solve the problems of fixed source distance which caused poor reliability and high failure rate of the existing oxygen activation tool,the flow inspection tool is designed.The new oxygen activation flow inspection tool has strong carrying capacity and good adaptability.The tool supports up to 13 probes,which can be combined freely to expand the flow measurement range.Increasing the crystal size of the near source probe increases the sensitivity of the probe and enhances the response of the tool to low-speed water flow.The water flow peak in the acquisition time spectrum is clear,which improves the quality of logging data and reduces the difficulty of interpretation.At the same time,combined with the field operation requirements,the production logging tool(PLT)data conversion sub is designed to combine the flow inspection tool and PLT tools for logging,so as to realize the measurement of production profile and water prospecting at the same time.
