| 摘 要： | 在特定的频段，泥质砂岩的复电阻率存在明显的频散现象，这种频散与地层含油饱和度的关系密切，这是目前复电阻率测井的基础。根据实验研究和理论研究结果，研制出了复电阻率测井仪器，该仪器基线稳定，测量准确，分辨率达到0.4 m，能够满足大庆油田薄层水淹层的测井要求。利用该测井仪器，在大庆油田进行了复电阻率测井应用，测井资料分析表明，低频电阻率与高频电阻率的比值能够较好地反映地层含油饱和度。

| Abstract: | Complex resistivity logging is based on the frequency dispersion of rock resistivity at special frequencies.The dispersion relates to water saturation in shaly sand formations.A complex resistivity well logging tool with electrode antenna was developed on the basis of theoretical and experimental study of rock physical properties.The complex resisitivity logging tool has been tested in Daqing Oilfield.It is stable and has a resolution up to 0.4m.The ratio of low frequency resistivity to high frequency resistivity calculated from the logs correlates well with oil saturation of reservoir.So the logging tool is suitable for the interpretation of water-flooded formation in Daqing Oilfield. |
