摘　　要：针对渤海油田氧活化水流测井面临的困难及难点提出了仪器组合选择方法、测量点选取的优化原则等测井工艺;研究了管内外水流活化峰相叠加时的解释方法,改善了氧活化水流测井的测量效果。针对油管内高流速超出原有仪器测量范围的问题,采用在原有仪器串中增加短采集短节的方法,实现了高注入井注水剖面的测量,最高流速能测到230 m/min;采用改进的双峰重叠测量工艺及解释方法解决了复杂管柱多股水流同时测井问题。海上应用表明,小直径(Φ38 mm)氧活化水流测井仪能应用到高注入量井,能验证封隔器密封性、探测管外漏点、高产水稠油井找出水层位,能够解决渤海油田防砂井的分层注水剖面的测量。To solve some tough problems in injection wells of Bohai oilfield now, a reasonable selective method is proposed for logging toolstring combinations, and optimization principle is given to choose measuring points. Interpretation method when two peaks overlap on the same probe is improved so as to make the measuring effect much better. Offshore log examples show that small diameter Oxygen-activation logging tool（Ф38 mm） can be used in high injection well to get injecting profile, vertify the packer tightness, detect the cross-flow outside oil pipe and find the source of water in production well which produces heavy oil and a plenty of water. A waterflow rate of 230 m/min is measured. The improved two-peak overlap/stacking weasuring ,ethnology and corresponding interpretation method have successfully solved such problem as simultaneous multiwaterflows loggings in the tubings.
