摘　　要：推靠式旋转导向钻井系统需要在井下把旋转态的电能传输给不旋转外套,传统接触式传电形式难以适应井下恶劣的工作环境。为此,基于ICPT技术,采用互感模型理论、Maxwell仿真计算并与试验验证相结合的方法,对非接触式旋转电磁机构的耦合性能、传输效率以及初、次级的谐振补偿措施进行了优化设计。研究了非接触电能传输装置的铁氧体形状尺寸、线圈匝数和安装位置的变化引起的该装置传输效率和功率的变化规律。研究结果表明:井下非接触电能传输装置能够满足现有静态推靠式旋转导向钻井工具的传电要求,轴向安装误差对传输效率和功率影响最大;该装置在轴向位移-3 mm位置传输效率和功率最高,并在效率最高点±3 mm范围内均满足电路传输的系统要求。研究结果对非接触式能量传输系统的研制具有一定的指导意义。The push-the-bit rotary steerable drilling system needs to transmit the rotating electrical energy to the non-rotating jacket downhole.The traditional contact power transmission form is difficult to adapt to the harsh downhole working environment.To address the problem,based on ICPT technology,combining the mutual inductance model theory,Maxwell simulation calculation and experimental verification,the coupling performance,transmission efficiency and primary and secondary resonance compensation measures of the contactless rotating electromagnetic mechanism are designed.The effects of the ferrite shape and dimension,coil turns and installation position on the transmission efficiency and power of the contactless power transmission device are studied.The research results show that the downhole contactless power transmission device can meet the power transmission requirements of the current static push-the-bit rotary steerable drilling tools.The axial installation error has the greatest impact on the transmission efficiency and power.The device at axial displacement-3 mm could provide the highest transmission efficiency and power,and meets the system requirements of circuit transmission within the range of the highest efficiency point±3 mm.
