摘　　要：羊三木油田经过长期注水开发,目前已进入高含水期,水淹层综合评价成为储集层评价所面临的主要难题。通过分析羊三木油田油层水淹前、后储集层物理性质变化特征,优选出能够反映储集层水淹特征的测井系列,并在此基础上分析了不同类型水淹层在测井曲线上的响应特征,提出了自然电位与不同径向探测深度电阻率曲线相结合的水淹层定性识别方法和基于核磁共振测井的水淹层识别及水淹级别划分方法。应用实例表明,上述方法在实际应用中的应用效果良好。After a long episode of water-flooded development,Yangsanmu oilfield has entered into high water cut stage.The comprehensive evaluation of watered-out zones has become the main difficult problem in reservoir evaluation.Through analyzing physical property variation features of watered-out reservoirs,from beginning to end,well logging series was sorted out,which can reflect the features of watered-out reservoir.On this basis,response characteristics of different watered-out zones in logs was analyzed,and a qualitative method of distinguishing the watered-out zones was put forward,which combines spontaneous potential with resistivity curves of different radial depths of investigation,and the methods of identifying watered-out zones and classifying watered-out status based on nuclear magnetic resonance logging,the examples indicated the effects of the above methods are good.
