摘要： A downhole percussive tool is disclosed comprising an interior chamber and a piston element slidably sitting within the interior chamber forming two pressure chambers on either side. The piston element may slide back and forth within the interior chamber as drilling fluid is channeled into either pressure chamber. Input channels supply drilling fluid into the pressure chambers and exit orifices release that fluid from the same. An exhaust orifice allows additional drilling fluid to release from the interior chamber. The amount of pressure maintained in either pressure chamber may be controlled by the size of the exiting orifices and exhaust orifices. In various embodiments, the percussive tool may form a downhole jack hammer or vibrator tool.

摘要： In one aspect of the invention, a swivel for use in a drilling operation comprises a body with a central bore adapted for threaded connection to a tool string component. At least one electrically conductive medium is rotationally supported within the bore and adapted to rotate with respect to an electrically conductive receiver that is rotationally fixed to and disposed within the body. The electrically conductive medium and the receiver are in electrical communication through an electrically conductive arm that is rotationally fixed to the electrically conductive medium and at least partially disposed within an electrically conductive fluid disposed within a reservoir. The reservoir comprises a rigid shape that is partially filled by the conductive fluid. A least one rotary seal is disposed intermediate the reservoir and the electrically conductive medium. The rigid shape of the reservoir is adapted to prevent the conductive fluid from accumulating around the rotary seal.

摘要： In one aspect, a downhole assembly has a downhole tool string component with a bore adapted to accommodate drilling mud. A fluid barrier is disposed within the bore and has a cylindrical portion substantially aligned with the bore. A drive shaft is sealed within and substantially coaxial with the cylindrical portion and has a first magnet disposed on its outer surface. A turbine assembly is disposed around the cylindrical portion of the fluid barrier and has an inner diameter and outer surface. The outer surface of the turbine assembly has a plurality of turbine blades. The inner diameter of the turbine assembly has a second magnet disposed within a region defined by the turbine blades and is in magnetic communication with the first magnet of the drive shaft, wherein when the drilling mud engages the turbine blades the first and second magnets rotate the drive shaft with the turbine assembly.

摘要： A downhole electrical transmission system having first and second tubular bodies coupled together by mating threads, each tubular body having a bore. An electrical conductor assembly is disposed within the bore of each tubular body. At least one end of each assembly has an electrical contact surrounded by a dielectric material, the electrical contact and dielectric material forming a polished, planar mating surface. The mating surfaces span an entire cross section of the end and are perpendicular to a central axis of the tubular bodies. The mating surfaces of each electrical conductor assembly are substantially engaged at a compressive load when the tubular bodies are fully mated.

摘要： A drill bit assembly comprises a bit body intermediate a shank and a working face. The shank is adapted for connection to a drill string. The drill string comprising a fluid passage at least partially disposed within the body. A hammer assembly is movably disposed within the fluid passage along it central axis, the hammer assembly comprises a proximal end stabilized by a centralized upper bearing and a distal end stabilized by centralized a lower bearing. The distal end protrudes out of the working face and the hammer assembly comprises a carrier between the upper and lower bearings. Wherein, under normal drilling operations the carrier is adapted to resist a fluid pressure within the fluid passageway such that the fluid pressure will further extend the distal end of the hammer assembly from the working face by pushing on the carrier.
