摘要： Electrical energy is produced by harvesting mechanical energy in the form of vibrations which are generally present in tools during the process of drilling oil wells. Electrical energy production is based on the Faraday induction principle whereby changes, i.e., movement, in magnetic flux through a coil induce an electric current through the coil. The changes in magnetic flux are produced by relative motion between at least one set of magnets and at least one coil. In particular, as the flux lines change due to the movement of the magnets, they remain perpendicular to both the direction of motion of the magnets as well as a planar or cylindrical surface defined by the coils. As a result, output for a given size of device is enhanced. Further, flexibility in adapting device form factor to particular shapes is enhanced. For example, a relatively flat device may be implemented using flexural bearing support of the magnets and coils on a printed circuit. The flexural bearings may also function as spring members that define the resonant frequency of the device. Alternative embodiments may be characterized by cylindrical or annular form factors.
摘要翻译：通过在钻井过程中通常存在于工具中的振动的形式收获机械能来产生电能。电能产生基于法拉第感应原理，其中通过线圈的磁通中的变化，即运动引起通过线圈的电流。磁通量的变化通过至少一组磁体与至少一个线圈之间的相对运动产生。特别地，随着磁通线由于磁体的移动而变化，它们保持垂直于磁体的运动方向以及由线圈限定的平面或圆柱形表面。结果，增强了给定尺寸的装置的输出。此外，增强了将设备形状因子适应于特定形状的灵活性。例如，可以使用在印刷电路上的磁体和线圈的弯曲轴承支撑来实现相对平坦的装置。弯曲轴承还可以用作限定装置的谐振频率的弹簧构件。替代实施例可以由圆柱形或环形形状因子表征。

摘要： Apparatus and methods are described for highly attenuating vibrations of a drillstring assembly while drilling. In one embodiment, vibrations are attenuated by introducing one or more vibration attenuation modules at appropriate assembly locations. For example, vibration attenuation modules may be inserted at locations where vibration energy is expected to be maximal. In one embodiment the vibration attenuation modules include cavities loosely packed with particles of solid material such as sand or metallic powder. In one embodiment, the cavity walls are rough and/or include geometric features that enhance vibration energy transfer to the loosely packed particles in the cavity(ies). The vibration energy is dissipated via friction and inelastic particle-particle and particle-wall collisions that occur as a result of drillstring motion.

摘要： A method facilitates transmission of electric signals across well components which move relative to each other in a wellbore environment. The method utilizes well components which are movably, e.g. rotatably, coupled to each other via one or more conductive bearings. Each conductive bearing has a conductive rolling element which enables relative movement, e.g. rotation, between the well components while simultaneously facilitating transmission of electric signals through the bearing. The method also involves coupling portions of the bearing to each of the well components, and those bearing portions may be connected with electric leads to enable flow of electric signals through the bearing during operation of the system downhole.

摘要： Steerable drilling systems for facilitating drilling according to a prescribed, three-dimensional trajectory are described. Steering may be achieved using passive actuators which require little or no power. For example, damping elements which couple a drill bit to a drill collar can be used to tilt the drill bit with respect to the drill collar. Alternatively, rotary cutting elements disposed on the drill bit may be used to control the force between the drill bit and the formation at different axial locations. The passive elements used to control the tilt or rotation of the rotary cutting elements are actuated in a certain pattern, e.g., geostationary, in order to achieve a desired deviation of the well bore while drilling ahead. One way to achieve this is through the use of field-sensitive materials, e.g. magnetorheological (MR) fluids, that change viscosity in response to an applied magnetic field.
