摘要： A method, apparatus and computer-readable medium for reducing a vibration of a drill string in a borehole. A sensor of the drill string obtains one or more measurements of a parameter of the vibration. A processor determines at least one force for controlling the measured vibration from the measured parameter. At least one actuator applies the determined at least one force against the borehole wall to control the vibration of the drill string.

摘要： An apparatus for use in a wellbore is provided, which in one embodiment includes a drilling motor and a steering unit placed about a shaft between a lower section of a stator in the motor and a drill bit. The steering unit includes a substantially non-rotating member and a force application member on the non-rotating member configured to radially extend the force application member from the non-rotating member. In another embodiment, the steering unit may include, rotating member configured to rotate a drill bit, a steering member configured to orient the drill bit along a selected direction, a first steering device configured to orient the steering member in the wellbore, and a second steering device configured to maintain orientation of the steering member when drilling the wellbore.

摘要： An apparatus for drilling a wellbore may include a first section, a second section, and a third section, all of which are rotatably interconnected with pivot bearings and positioned along a drill string. The second section and the third section may be configured to form a controllable bend angle in the drill string. The first section, the second section, and the third section may be configured as sleeves that surround a portion of the drill string. One or more sections may include locking pads that selectively engage a wall of the wellbore. A hydraulic locking device for controlling a direction of rotation of the second section may include one or more brake elements and a reverse spinning sleeve. A first brake element may be used engage the reverse spinning sleeve and a second brake element may be used to engage a drive shaft.
