摘要
介绍了高频等参数感应的基本原理。以胜利油田比较典型的 3口井为例 ,详细分析了高频感应资料在划分薄夹层、确定储层流体饱和类型、评价储层电阻率空间分布等方面的应用。研究结果表明 ,高频感应具有极高的纵向分辨率和较好的径向探测特性 ,能够准确计算地层真电阻率、侵入带电阻率及侵入半径 ,通过与常规感应及薄层测井资料的对比 。
Take the typical three wells in Shengli Oilfield for example, analyzed in detail are the applications of the high frequency induction logs in identifying the streaks, determining the types of reservoir fluid saturation and evaluating the spatial distribution of reservoir resistivity and so on.The results of research indicate that this tool has highly vertical and radial resolution. It can calculate accurately the resistivity of formation, the resistivity of the invaded zone and the invaded radius. In comparison with conventional induction and thin bed logging, it is proved that the tool has higher reliability and better advantage.
