摘要
基于有限元分析方法,对新型随钻录井电阻率探头进行数值模拟研究,结果表明:该仪器测量信号动态范围较大,探测深度浅,受井眼影响小,能够较准确测得泥浆电阻率,实时反映储集层信息。
Based on the theory of finite element method(FEM),a numerical simulation research is made on a new loggingwhile-drilling instrument used for probing mud-resistivity.Results show it has large dynamic range of the measurement signal,shallow probing depth and small borehole effects,so mud-resistivity can be measured accurately and reservoir information can be reflected timely.
