摘要
利用高效的数值模式匹配方法（NMM）求解二维轴对称介质的位场格林函数，并结合表面积分方程法来匹配球形聚焦电极系上复杂的激励条件，圆满地解决了复杂介质中位场的分析，其数值结果与文献数据相吻合。本文还讨论了无源等位体对球形聚焦电极系测井响应的影响。
In this paper, potential field Green's function in the complex medium is solved by using the efficient numerical mode-matching method, which combined with surface integral equationmethod to match the complex excited condition on the spherically focused log (SFL), so that theproblem of potential field is resolved satisfactorily in the complex medium. The numetical results showexcellent agreement with the reference. lt is found that NMM program is much faster than the program using the FEM, hence it is useful for routine interpretation of resistivity logs. Meanwhile, thelogging response has been discussed in different distances between SFL tool and the passive electrode.
