| 英文摘要 | Electromagnetic telemetry systems have attracted considerable attention owing to their increasing applications in measurement-while-drilling. In simulations, the long, thin drill string of the telemetry system is simplified as an antenna penetrating a layered medium, and, typically, there is a source segment near the drill bit to induce excitations. In this study, a method to accurately and efficiently simulate an electromagnetic telemetry system within a transversely isotropic medium was proposed. The method of moments was utilized to discretize the current distributed along the drill string, and then we estimated the current distribution. Subsequently, the scattering field was analytically simulated through the integration of the product of the solved current distribution and Green's function. The proposed method does not require complex numerical simulations for the integration and is verified through comparisons with that from the COMSOL commercial software, which is based on the finite element method. The effects of the conductivity of the drill string, operation frequency, transversely isotropic anomaly, target anomaly layer were also estimated using different models with the transversely isotropic medium. It reveals that the high conductivity of the drill string could improve the radiation efficiency of the source. The current distribution along the drill string and the voltage signals received on the ground are more sensitive to variations of transverse components of conductivity than its vertical components. |
