inductive coupler for use in a downhole environment

摘要

inductive coupler for use in a downhole environment. Inductive couplers for use in a downhole environment are described. An exemplary inductive coupler for use in a downhole environment includes a body defining a cavity and magnetic material positioned in the cavity. The exemplary inductive coupler also includes a coil adjacent to the magnetic material, the coil formed with a number of wire loops, and a first metal cap coupled to the body to enclose the cavity. the metal cap being electrically coupled to the body to form a substantially contiguous electrically conductive surface around the cavity.
