Systems and Methods for Downhole Electrical Switching

摘要

Systems and methods for alternately coupling equipment at the surface of a well to different ones of a set of downhole tools installed in the well. In one embodiment, a system includes surface equipment positioned at the surface of a well and a plurality of downhole tools that are installed downhole in the well. A switcher is positioned in the well between the surface equipment and the downhole tools. An upper line is electrically connected between the surface equipment and the switcher, and a set of lower lines are electrically connected between the switcher and a corresponding set of of downhole tools. The switcher alternately couples different ones of the lower electrical lines electrically to the upper electrical line. At any time, the upper electrical line is electrically coupled to only one of the lower electrical lines.
