Calculation of Electromagnetic Wave Logging Response by Using the Numerical Mode Matching Method
The Numerical Mode Matching (NMM) method as an efficient half-numerical and half-analytical algorithm has been successfully applied in the simulation of electromagnetic fields with multi-layer structure domains for both high and low frequency applications. In this paper, the response of the Logging While Drilling (LWD) problem with multiple-layer structure soil is simulated by using the NMM method. The simulated drill collar consists of one or two transmit-ting coils and two receivers. This device can be applied to detect physical property parameters of the soil or medium surrounding the borehole. According to the simulation results, the phase difference of signals received by the two receivers, but not the difference of the signal amplitude, is reflected by the parameters observably. In the numerical simulation, a model of LWD problem including drill collar is adopted. The drill collar is considered as specific layers of the earth to simplify the simulation.
