  • Toroidal coupled telemetry apparatus
    Patent number: 4525715
    Abstract: A logging telemetering system comprising a toroidal coupled telemetry apparatus including a primary winding carrying bore hole data, wrapped around at last one torroid core mounted within a drill collar. The toroid core is further wrapped with at least one secondary turn which is connected to the drill collar for enhancing the efficiency of inducing a current carrying the borehole data in the drill string for transmission to the surface. One half turn of the secondary winding is provided by an insulated portion of the drill collar, and the balance of the secondary winding is composed of an electrically conductive strap wound around the toroid core.

  • Point gap assembly for a toroidal coupled telemetry system
    Patent number: 4387372
    Abstract: An insulated point gap assembly for a toroidal coupled telemetry system wherein a drill collar (38), operable to be connected to a lower portion of a drill string (32), carries a toroidal core having primary windings (88) and secondary windings (130). An aperture (154) is laterally fashioned through the drill collar. A conductor (150) is connected to one end of the secondary and extends through the aperture and the other end of the secondary is connected to the drill collar. The conductor is surrounded by an electrical insulation member (152). In a preferred embodiment, an axially extending sleeve of insulating material (156) is applied about the drill collar at the location of the conductor (150) to further isolate the conductor 15 from the drill collar.
