The working principle of the array lateral logging tool is introduced.Based on analyzing the classification of the formation model,the progress in the research and application of the three-dimensional numerical mode matching method (3D NMM) for solving three-dimensional models is described from the following three aspects,that is,the recursion method,numerical calculation and the processing method of excitation source.The application of 3D NMM in horizontal well and deviated well is discussed,and the disadvantage existing in solving deviated well is also discussed,and the three main directions in the future research of 3D NMM are pointed out:the new recursive method,the fast algorithm for numerical solution and the application of 3D NMM in slope problem.%以阵列侧向电极系为例,阐述其工作原理.在分析地层模型分类的基础上,针对求解三维模型的三维数值模型匹配法(3D Numerical Mode-matching Method,3D NMM),从解析式的递推方法、数值解的计算和激励源的处理方法3个方面,论述3D NMM的研究与应用进展,讨论3D NMM在水平井和斜井中的应用及其求解斜井问题时存在的不足,并指出3D NMM未来研究的3个主要方向:解析式的递推新方法、数值解的快速算法和斜井问题中的应用.
