分层媒质中三侧向电阻率测井响应的高效数值分析

The Laterolog-3 Tool Interpretation Using the Efficient Method in a Complex Environment

利用高效的数值模式匹配方法，求解复杂介质的位场格林函数，并结合表面积分方程法来匹配三侧向测井电极系上复杂的激励条件，圆满地解决了复杂介质中位场分析，其数值结果与文献数据相吻合。

In this poper,potential field Green's function in the complex medium is solved by using the efficient numerical mode-matching(NMM)method,which combine with surface integral equation method to match the complex excited condition on the laterolog-3 tool,so that the problem of potential field analysis is resoved satisfactorily in a complex medium.Its result is in agreement with the data in the reference.Particularly the computation speed of the NMM program is much higher than the finite-element method (FEM) program,and hence can be used for routine interpretation of field logs.
