摘要
本文从井下激励装置、无线传输信道、编码和调制以及地面接收四个方面探讨了电磁波随钻测量系统无线传输技术。指出国内的研究与实际应用存在一定的差距,并以俄罗斯ZTS电磁波随钻测量系统为例,分析了国外先进的井下无线传输技术。
This （ EM-MWD ）, paper discusses underground transmission technology of electromagnetic measurement while drilling including underground stimulation device, channel for underground transmission, coding and modulating, as well as receiver on the ground. By analyzing the technology Russia-made ZTS series of EM-MWD system used, this paper points out theoretical research in this field is far from application in China, and how to improve the development of EM-MWD system.
