发明名称 DOWNHOLE INDUCTIVE COUPLER ASSEMBLIES
摘要 Inductive couplers for use in a downhole environment are described. An example inductive coupler for use in a downhole environment includes a body defining a cavity and magnetic material positioned in the cavity. The example inductive coupler also includes a coil adjacent the magnetic material, the coil formed with a number of turns of wire, and a first metal cover coupled to the body to enclose the cavity. The metal cover being electrically coupled to the body to form a substantially contiguous electrically conductive surface surrounding the cavity.
