中文摘要 | Infinite element method (IEM) is introduced to the 3D numerical mode-matching (NMM) method to solve the 3D electric logging problem. This method divides the infinite field domain of each layer into inner and outer field domains, the matrices are formed by standard finite element method (FEM) in both inner and outer domain, the Kelvin transformation is introduced and the matrices are formed by a new infinite element format. Matrices of two different parts are coupled in the domains ' common interface to form the final matrices of the original problem. This method generates smaller size of generalized matrices than the original 3D NMM method. Results show that the new method spends only 1/7 CPU time and uses only 1/3 memory of the original method. This new method can be widely applied to calculate electromagnetic logging responses. |
