摘要： A wireline logging assembly includes a cable having primary conductors, secondary conductors, and a central conductor. A first power source excites the primary conductors using a first propagation mode. A first telemetry transceiver excites the primary conductors using a second propagation mode orthogonal to the first mode. A second power source excites the secondary conductors and a second telemetry transceiver excites the central conductor. In one embodiment, the diameter of the primary conductors is greater than a diameter of the secondary conductors. The primary conductor includes four primary conductors symmetrically positioned around the center conductor and the secondary conductors include a secondary conductor positioned in the interstice between each pair of adjacent primary conductors. The first telemetry transceiver is preferably connected to a primary winding of a first transformer while the first power source is connected to center taps of the first and second secondary windings of the first transformer.
