摘要： Extendable elements of downhole tools are provided having an extension direction component perpendicular to a tool axis, wherein a force is applied to the extendable element when in operation. The extendable elements comprise a first cross-section that includes the extension direction component, a first surface configured to receive a first force component of the force, the first force component substantially perpendicular to the first surface and a second surface configured to transfer at least a portion of the first force component of the force to a body of the downhole tool. The second surface and the extension direction component perpendicular to the tool axis draw a first angle that is between 0° and 90°.

摘要： An apparatus for use in a wellbore is disclosed that in one non-limiting embodiment includes a flow restriction device that that contains a channeling element having a fluid flow passage, a restriction element spaced from the channeling element defining a gap between the restriction element and the channeling element, wherein relative movement between the restriction element and the channeling element obstructs flow of a fluid flowing through the flow passage to increase pressure in the fluid across the device. In one embodiment an activation device displaces one of the channeling element and the restriction element to adjusts or alter gap in response to certain changes in the pressure across the restriction device.

摘要： An oscillating shear valve system for generating pressure fluctuations in a flowing drilling fluid comprising a stationary stator and an oscillating rotor, both with axial flow passages. The rotor oscillates in close proximity to the stator, at least partially blocking the flow through the stator and generating oscillating pressure pulses. The rotor passes through two zero speed positions during each cycle, facilitating rapid changes in signal phase, frequency, and/or amplitude facilitating enhanced, multivalent data encoding. The rotor is driven by a motorized gear drive. In one embodiment, a torsional spring is attached to the motor and the resulting spring mass system is designed to be near resonance at the desired pulse frequency. The system enables the use of multivalent encoding schemes for increasing data rates.

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
