摘　　要：利用数值模式匹配理论，对具有轴对称的任意二维非均匀介质中位场的格林函数给出数值解。应用这一数值解，对复杂介质环境中双侧向测井响应进行了高效的数值分析。由于采用了半解析-半数值的混合方法，较之二维有限元分析具有很高的效率，节省大量计算时间。In this paper the numerical solution of Green's function of potential in 2-D arbitrary inhomogeneous media with axial symmetry has been given by using the numerical mode matching(NMM) theory.Then efficient numerical analysis has been made for response of Dual Lateral Logging tool in complex media in term of above Green's function.This analysis has much higher efficience than 2-D finite element method and save much computer cost due to using me half-analytic, half numerical hybrid method.
