摘　　要：为了实现旋转导向钻井系统中近钻头传感器测量数据的传输,提出了一种基于松耦合的无线电磁短传系统设计方案,分析了无线电磁短传信道并建立其模型,介绍了系统关键部件的设计,并对其数据传输性能进行了测试试验。试验结果表明,设计可以满足实际工程应用的要求,并为后续研究提供了试验依据。In order to satisfy transmission of data measured by sensor near to hit in rotary steering drilling system,the design of the short distance wireless electromagnetic transmission system based on loosely coupled inductive is designed in this paper. The short distance wireless electromagnetic transmission channel is analyzed and the model is established, the key parts of which is designed at the same time,and the test of data transfer performance is accomplished.The result of test show that the design can satisfy the requirements of practical engineering applications and provide an experimental basis for further study.
