摘要
目前,钻井中井下检测信号的传输主要运用泥浆脉冲、电磁波等方式。随着井深的增加、复杂结构井和欠平衡井的增多以及对传输速度要求的提高,电缆信号传输必然是今后智能钻井的发展方向。通过对半个多世纪来各类电缆信号传输的设计进行归类,详细介绍了其设计原理,提出了电缆信号传输设计的基本要求与难点。
Presently, the transmission of downhole signal mainly uses mud pulse and electromagnetic wave. However,with the increase of well depth, complex architectual well and transmittable speed, the wired signal transmission is the inevitable development trends of intelligent drilling. The paper classifies almost all of the designs on current wired signal transmission,and expatiates on their design principle. In the end, the paper puts forward the basic requirements and the exiting difficulty of the design.
