inductive coupler assembly for use in a downhole environment, and method of colluding energy and communications in a downhole environment

摘要

inductive coupler assembly for use in a downhole environment, and method of conducting power and communications in a downhole environment. An inductive coupler assembly for use in a downhole environment and related methods is described. An exemplary inductive coupler assembly includes a first inductive coupler having first and second magnetically coupled coils and a second inductive coupler having third and fourth magnetically coupled coils. the first and third coils are coupled to a first pair of signal lines and the second and fourth coils are coupled to a second pair of signal lines. the first inductive coupler is for magnetically conducting a differential communication signal between the first and second pairs of signal lines, and the second inductive coupler is for magnetically conducting a common mode power signal between the first and second line pairs.
