CableLink? Solution for Wireline Systems

摘要

Most if not all of the longer horizontal directional drilling (HDD) crossings require a wireline guidance systemrnto track the drill tool. These systems use a wire inside the drill string to deliver power to the transmitter andrnto transmit locating data back to the drill crew. Every time a new drill pipe is added or removed, a wirernconnection is necessary, which typically consists of a butt splice with heat shrink. The connection procedurernintroduces labor, time, and safety issues—not to mention the potential for a faulty connection. This paperrndescribes a new product, the CableLink?u0003connection system. This system is permanently installed in therndrill pipe prior to drilling, and the electrical connection is made when the pipe ends are threaded together.rnThe paper discusses the development of this novel product and the results of laboratory and field tests,rnincluding a brief description of HDD projects undertaken using the system. The CableLink system not onlyrnprovides a reliable electrical connection, it also delivers direct cost savings and increases in productivity.
