摘要： An apparatus for drilling a directional wellbore 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 the 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 a tilt sensor that provides measurements relating to tilt of the lower section. A controller determines a parameter of interest relating to the tilt for controlling drilling of the directional wellbore.

摘要： A system for acquiring directional information about a geologic formation includes at least one directionally sensitive nuclear magnetic resonance (NMR) assembly disposed at a borehole string including the downhole component. The at least one NMR assembly includes at least one magnet configured to generate a static magnetic field and at least one coil configured to generate an oscillating magnetic field, the at least one NMR assembly configured to perform an NMR measurement of at least one sector of a formation region. The system also includes a processing device configured to receive NMR measurement data from the at least one NMR assembly. The processing device is configured to analyze the NMR measurement data to estimate a parameter of the sector, determine a direction of the downhole component based on the estimated parameter; and steer the downhole component according to the determined direction.

摘要： An apparatus for controlling flow of a fluid includes a closure member, a biasing member applying a biasing force to the closure member, and a sealing member receiving the closure member. A dampener is operatively connected to the closure member and may resist a force applied to the closure member. A fluid seal may be formed when the biasing member presses the closure member against the sealing member. The apparatus may include a wellbore tubular in which the fluid conduit is formed and the closure member and sealing member may cooperate to control fluid flow along the fluid conduit. The apparatus may include an actuator configured to control the force applied to the closure member. The actuator may adjust the biasing force, and/or the dampening force. Also, a controller may control the actuator and may be responsive to a signal generated at a surface location, a signal generated at a downhole location, and/or a signal generated by a sensor.
