摘　　要：Sondex噪声频谱测井仪(NTO)通过测量井下流体流动产生的噪声频率和幅度大小,判断井下流体类型和流动特征,分析NTO测井资料在产液剖面评价以及漏失检测方面的应用情况,可有效识别井筒内流动、漏失、窜槽以及储层内的流体流动特征,可与Sondex的其他电缆测井仪器组合以存储或直读的模式进行测井作业,同时1支仪器串上可以挂接多个NTO仪器,更高效、精确地确定特定噪声位置。该测井技术在评价储层流动特征,检测管柱漏失、窜槽等方面准确可靠,为监测井下流体流动特征提供了可靠方法。Sondex’s Spectrum Noise Logging Tool(NTO)judges the fluid type and characteris-tics of downhole fluid by measuring the frequency and amplitude of noise.The log data evaluated can effectively identify the flow characteristics in wellbore fluid,leakage,channels or characteristics in reservoir.NTO can be combined with other wireline tools of Sondex to perform logging operations in a storage or direct reading mode,and connect multiple NTO tools to one tool string,make it possible to pinpoint the location of specific noise more efficiently and accurately.This technology is accurate and reliable in evaluating reservoir flow characteris-tics,detecting leakage and channels,which provide a reliable method for monitoring downhole fluid flow characteristics.
