摘　　要：多功能氧活化水流测井由于采用"双发多收"的测量模式,一次下井可以同时获取油、套管内外的水流速度和方向,因此,被大量用于注入剖面测井。其不但适合于同位素沾污严重、高伽玛本底异常、存在大孔道地层的注入剖面测试,还可以用于查窜、找漏。在此基础上,通过改变测井工艺以及改进解释方法,还可以较好地识别出注入剖面测井中的"反吐"现象和提高在非对称谱中渡越时间的求解精度。Multifunetional Oxygen Activation Water Flow Logging is widely used in injection profile logging due to its logging mode which enable access to oil and the velocity and direction of water flows in and out of the casing. It＇s not only applied to the injection profile logging heavily contaminated by isotope with abnormal high gamma background and macro pore path formation but also can be used to check for leaks and channeling. What＇s more, by revising log- ging techniques and interpretations, workers can spot bursts during injection profile logging more easily and improve the accuracy of transition time on asymmetric chart.
