Downhole inductive coupler with ingot

Abstract

An inductive coupler and method for a downhole tool such as a drill pipe comprising an electrically conductive ingot cast into a magnetically conducting electrically insulating (MCEI) annular mold. The MCEI mold may comprise an annular channel comprising a first perforation and one or more second perforations. The ingot may comprise first and seconds with sockets proximate the respective ends. The first perforation may comprise an electrical connection to a ground pin in the downhole tool. The one or more second perforations may comprise electrical connections to a similarly configured ingot within the downhole tool and to electrical equipment within the drill pipe. The ingot may further comprise cleats and flutes. The ingot may comprise an annular passageway around the interior of the ingot. The ingot may be sealed within the channel and each of the perforation may comprise a seal insolating the electrical connections from the downhole environment.
