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.

摘要： L'objet de l'invention est un appareil de forage pétrolier, gazier ou géothermique comportant un outil central et un trépan coaxiaux dans lequel l'outil central est entraîné par le rotor d'un moteur de fond alimenté par la boue de forage et dans lequel le trépan est entraîné, depuis la surface, par les tiges d'un train de forage appartenant à un système rotary, ces mêmes tiges soumettant l'appareil à un effort axial. Il est caractérisé en ce que, entre le stator (4) du moteur de fond et l'embase (5) du trépan, existe une liaison prismatique qui permet le déplacement axial relatif des deux outils et en ce qu'un ressort (6) est interposé entre le stator (4) et l'embase (5) de manière à être contraint par le stator quand l'outil central tend à prendre du retard par rapport au trépan dans leurs mouvements d'avance respectifs, afin de contrôler le déplacement axial relatif des deux outils et de répartir entre eux, en fonction de ce déplacement, l'effort axial auquel l'appareil est soumis. Application à l'industrie du matériel de forage notamment pétrolier, gazier ou géothermique.

摘要： A CV joint for a downhole drilling motor includes a center shaft including a top shaft section and a bottom shaft section. The top shaft section is at least partially housed within a cavity of a first insert, which is housed within a cavity of a rotor adapter. The bottom shaft section is at least partially housed within a cavity of a second insert, which is housed within a cavity of a drive shaft adapter. An outer surface of the top and bottom shaft sections may include multiple top shaft pockets and multiple bottom shaft pockets, respectively. The first and second inserts may each include a series of recesses. Top shear members may be partially housed within the top shaft pockets and the recesses of the first insert. Bottom shear members may be partially housed within the bottom shaft pockets and the recesses of the second insert.

摘要： A magnetic drive device may comprise a stator comprising a plurality of windings for generating a first number of magnetic pole pairs and a rotor comprising a plurality of permanent magnets for generating a second number of magnetic pole pairs that differs from the first number of magnetic pole pairs. The magnetic drive device may further comprise a plurality of free-spinning interpole elements disposed within an air gap between the stator and the rotor. The interpole elements may produce a magnetomotive force and harmonically couple the magnetic pole pairs of the stator with the magnet pole pairs of the rotor.
