摘要
本文对微球聚焦测井仪小极板进行研究。利用有限元法计算了小极板的均质及非均质人值, 并与实验结果进行了比较, 结果表明理论值与实验值吻合较好, 说明了理论计算的正确性。给出了对应于小极板的泥饼校正图版及屏流比曲线, 对小极板的推广应用有实用价值。
Abstract
This paper makes research on the mini-electrode pad of microspherically focused logging tool.The calculation of its uniform and nonuniform K values is carried out via finitc-elemcnt mcthod.The comparison between thc calculated values and experimental ones shows that the theoretical values are well coincident with the experimental ones, which demonstrates the correctness of the theoretical calculation. The mud cake correction chart and shielded current ratio curve corresponding to the pad are also presented, which are of practical benifit to populize the pad.
