Reinforced MCEI transducer for downhole communication

Abstract

A reinforced MCEI transducer for drill pipe telemetry comprising an annular ferrite trough. The ferrite trough may be a single piece trough or it may be made up of ferrite trough segments arranged intimately end for end. The single piece trough may comprise one or more annular mechanical reinforcements such as a rod, a tube, or a mesh. Trough segments may comprise mechanical reinforcements that when the segments are arranged end for end, they thereby act like continuous annular reinforcements. The annular reinforcements may be embedded radially within the annular ferrite trough. The mechanical reinforcements may be nonelectrically conductive, or they may be electrically conductive. The reinforcements may comprise a metal or a nonmetal, or a polymer. An annular electrically conductive wire coil may be disposed within the ferrite trough. The ferrite trough may comprise one or more perforations. The ferrite trough may be housed within an annular polymeric block.
