摘要： An apparatus for use in a borehole may include a rotor having at least one set of magnetic elements and a cylindrical stator having a winding flowing current in a direction transverse to a long axis of the stator. The polarity of each magnetic element of the rotor may be arranged to alternate along a long axis of the rotor. The stator may be in sliding engagement with the rotor and have a core formed at least partially of laminations aligned along a plane co-planar with the long axis of the stator. Energizing the winding principally causes relative sliding between the rotor and the stator. A method for performing an operation in a borehole includes forming a well tool having at least one linear motor as described above, conveying the linear motor into the borehole, and operating a well tool by activating the linear motor.

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.

摘要： A rotatable downhole cutting tool configured for enhanced drive consistency in low power circumstances. The tool is equipped with a hydraulic axial drive actuator suitable for use in wireline deployment. The actuator itself includes a reciprocating piston with a ball screw that threadably interfaces a ball nut for dampening the axial drive imparted by the piston. As such, even though hydraulically driven at generally well under about 10 horsepower, bounce in the axial drive is substantially eliminated. This is particularly advantageous where cutting is to be applied to downhole metal based obstructions.
