发明名称 Inductive coupler for well tools
摘要 An inductive coupling device for coaxially arranged tubular members where the members can be telescopically arranged and the liner member has a magnetic core assembly constructed from magnetic iron with cylinder sloped ends and the outer member has an annular magnetic assembly aligned with the core assembly. The tubular members are non-magnetic enclosures and together with a gap spacing define an effective air gap.
