摘　　要：为了改进特殊有缆钻具制造工艺复杂的现状,提出了一种基于HFSS软件的井下无线感应信号传输装置仿真模型。通过建立感应式和谐振式仿真模型,计算仿真信号传输特性,验证设计模型的关键参数如匝数、螺距、包裹材料等对传输特性的影响。通过分析仿真模型的结果校正设计方案,得出传输衰减小、可实际应用的仿真模型,进而指导实物模型设计,提高研发效率,降低研发成本。测试结果表明,无线感应耦合信号传输模型具有可行性,与实物具有良好的一致性,衰减误差可在-5 dB以内,为实物制作提供了重要依据。This model design of high frequency wireless induction signal transmission device is based on HFSS simulation software,in order to improve the complex manufacturing process of special wired drilling tool.By establishing induction and resonance simulation models,the simulation signal transmission characteristics are calculated and compared with the physical model to verify the influence of the parameters of the design model,such as turns,pitch,wrapping material,on the transmission characteristics.By analyzing and correcting the design scheme through the simulation results of the model,a simulation model with high consistency with multiple physical models is obtained,which can guide the design of physical models,and greatly improve the efficiency,reduce the cost and save the time of R&D.Through the model simulation method designed in this paper,the feasibility of wireless induction coupled transmission is verified.It is highly consistent with the physical model,deviation can be less than-5 dB,which provides an important basis for the physical production.
