摘　　要：能谱水流测井是近年来发展的监测井下流体动态的一种测井方法,由于它不使用放射性物质,对井筒沾污、地层污染的影响较小,同时也为油田注入剖面的动态监测提供了准确的依据。详细介绍了9探头氧活化能谱水流测井的测量原理与仪器介绍及渡越时间的求取方法,并针对塔里木油田能谱水流测井存在的高伽马本底问题、深度归位问题、找水找窜问题进行了详细分析,提出解决方法,应用效果良好。Spectral water flow logging was a logging method that has been developed in recent years for monitoring the dynamic of downhole fluid,in which radioactive material was not used,so it had a little affect and less damage to the wellbore and formation;and at the same time it also provided accurate basis for dynamic monitoring of injection profile in the oilfields.The principles of measurement of nine probes spectral water flow logging and the method of calculating transit time of the instrument are introduced in detail,the existed problems of the spectral water logging in Tarim Oilfield,such as high gamma background,depth homing problem,water and its channeling detection are also analyzed in detail,solutions are proposed and the good result is obtained.
