摘要： A method and an arrangement for magnetically determining a position using a permanent magnet is described, wherein the vector and local gradient of the magnetic flux density of the permanent magnet is measured using a position sensor, and the position and orientation of the magnetic dipole of the the permanent magnet relative to the position sensor is calculated from the measured values. A spherical permanent magnet having homogenous magnetization is used in the method and the arrangement, preventing previously present cross-sensitivity between the position and orientation determination, and allowing measurement without prior calibration.

摘要： An exemplary device carried on a rotating drill string includes an actuator that moves force application members and an associated controller. The force application members are actuated by an eccentricity between a force application members housing and the actuator. The controller synchronizes the extension of the force application members with the rotation of the drill string such that a steering force applied by the force application members is applied in the same azimuthal direction. The controller may also control magnitude of the steering force by adjusting the eccentricity. Another exemplary device maintains a wellbore device, such as a sensor, in a substantially non-rotating condition relative to a reference frame. The device includes a sensor conveyed by a rotating wellbore tubular, a drive configured to rotate the sensor; and a processor that controls the drive to maintain the sensor in a substantially non-rotating condition relative to the reference frame.

摘要： A system for drilling a borehole into the earth's subsurface includes a drill bit configured to rotate and penetrate through the earth's subsurface, and a vibration isolation device configured to isolate vibration that is caused at the drill bit, the vibration having an amplitude. The amplitude of the vibration downhole of the vibration isolation device is at least 20% higher than the amplitude of the vibration uphole of the vibration isolation device.

摘要： A device for generating pressure pulses includes a valve member disposed in a fluid passageway, the fluid passageway including a restriction, the valve member movable by an actuator relative to the restriction to generate a pressure pulse in a fluid in the fluid passageway based on varying a relative position between the valve member and the restriction and creating a differential pressure across the fluid passageway, the differential pressure applying a first force on the valve member. The device also includes a piston member in hydraulic communication with the differential pressure, the differential pressure applying a second force on the piston member, the piston member having a locomotive mechanical connection to the valve member.

摘要： An apparatus for drilling directional wellbores is disclosed that in one non-limiting embodiment includes a drive for rotating a drill bit, a deflection device that enables a lower section of a drilling assembly to tilt about a member of the deflection device within a selected plane when the drilling assembly is substantially rotationally stationary to allow drilling of a curved section of the wellbore when the drill bit is rotated by the drive and wherein the tilt is reduced when the drilling assembly is rotated to allow drilling of a straighter section of the wellbore, and at least one seal that isolates at least a surface of the member from outside environment. The at least one seal is lubricated by a sealed hydraulic unit

摘要： A drilling system and method of drilling a wellbore. The drilling system includes a tubing, an orientation device affixed to the tubing, a drilling sub having a housing having a first section and a second section, wherein the first section is coupled to a movable element of the orientation device, a shaft disposed in the housing, the shaft coupled to the drive and to the drill bit, and a pivot member coupled to the first section and second section of the housing. The second section of the housing tilts relative to the first section of the housing about the pivot member when the orientation device is rotationally stationary to allow drilling of a curved section of the wellbore. Rotation of the housing via the orientation device reduces the tilt between the first section and the second section to allow for drilling of a straight section of the wellbore.
