    • 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.

    • A bearing for a wellbore tool includes a flow device. The flow device may be a pump such as a positive displacement pump or a hydrodynamic pump. In arrangements, a pump stator connects to a wellbore wall. A pump rotor rotates with a drilling motor, and/or a drill string. Rotation of the pump rotor may generate a pressure differential to displace the fluid. The pump may be configured to flow fluid across a gap between a rotating section and a non-rotating section of the bearing. The fluid may be drawn from a wellbore annulus and also returned into the wellbore annulus. The bearing may support thrust loadings and/or a radial loadings. In embodiments, inserts in the bearing may be used to filter the fluid.
    • 用于井眼工具的轴承包括流动装置。 流动装置可以是诸如容积式泵或流体动力泵的泵。 在排列中,泵定子连接到井筒壁。 泵转子与钻孔马达和/或钻柱一起旋转。 泵转子的旋转可产生压差以移动流体。 泵可以构造成使流体流过轴承的旋转部分和非旋转部分之间的间隙。 流体可以从井眼环带抽出并且还返回到井眼环形空间中。 轴承可以支撑推力载荷和/或径向载荷。 在实施例中,轴承中的插入件可用于过滤流体。

    • A method for determining wellbore trajectory includes determining survey parameters in the wellbore; measuring force parameter(s) in the wellbore; and correcting the survey parameters using the measured force parameter(s). The downhole measured force parameters may include forces associated with an operation of a steering device such as an internal reaction force, and/or a bending moment. In variants, the method may include measuring a wellbore temperature; measuring a wellbore parameter in addition to the temperature; and correcting a survey parameter using the measured parameter and the measured temperature. These methods may include correcting survey parameters using measured wellbore diameters. Also, a processor in the wellbore may be programmed to perform the correction while in the wellbore and/or control a steering device using measurements provided by a sensor for measuring internal reaction forces.
