| 摘要 | An apparatus for maneuvering a tool string within a borehole of a subterranean well includes a magnetic tractor casing with a central bore. A tractor body is located within the central bore of the magnetic tractor casing. A plurality of magnets are spaced along an outer surface of the tractor body, the plurality of magnets operable to generate a second magnetic field to interact with a first magnetic field of the magnetic tractor casing, to maintain an annular space between the tractor body and the magnetic tractor casing. A plurality of angled opening assemblies are spaced along the tractor body, each of the angled opening assemblies shaped to direct fluid away from the tractor body, to maintain an annular space between the magnetic tractor casing and the borehole of the subterranean well. | ||

| 主权项 | 1. An apparatus for maneuvering a tool string within a borehole of a subterranean well, the apparatus comprising: a magnetic tractor casing, the magnetic tractor casing being a cylindrical tubular member with a central bore, a first end and a second end opposite the first end; a tractor body located within the central bore of the magnetic tractor casing, the tractor body being an elongated member; a plurality of magnets spaced along an outer surface of the tractor body, the plurality of magnets operable to generate a second magnetic field to interact with a first magnetic field of the magnetic tractor casing, to maintain an annular space between the tractor body and the magnetic tractor casing; and a plurality of angled opening assemblies spaced along the tractor body, each of the angled opening assemblies shaped to direct a fluid away from the tractor body, to maintain an annular space between the magnetic tractor casing and the borehole of the subterranean well. | ||
