摘要： The present disclosure addressed apparatus and methods for forming an annular isolator in a borehole after installation of production tubing. Annular seal means are carried in or on production tubing as it is run into a borehole. In conjunction with expansion of the tubing, the seal is deployed to form an annular isolator. An inflatable element carried on the tubing may be inflated with a fluid carried in the tubing and forced into the inflatable element during expansion of the tubing. Reactive chemicals may be carried in the tubing and injected into the annulus to react with each other and ambient fluids to increase in volume and harden into an annular seal. An elastomeric sleeve, ring or band carried on the tubing may be expanded into contact with a borehole wall and may have its radial dimension increased in conjunction with tubing expansion to form an annular isolator.

摘要： A hydraulic control and actuation system for downhole tools. In a described embodiment, a hydraulic control and actuation system includes an internal chamber serving as a low pressure region and a well annulus serving as an energy source. A valve assembly provides selective fluid communication between alternating opposite sides of a piston and each of the energy source and low pressure region. Displacement of the piston operates a well tool. Operation of the valve assembly is controlled via telemetry between a remote location and an electronic circuit of the system.

摘要： Disclosed herein are various embodiments of power conversion systems and methods employing synchronous multi-phase AC-to-DC conversion. In one embodiment, a power converter comprises a transistor bridge and a switching controller that operates the transistor bridge in response to AC voltage threshold crossings. The switching controller may include a period counter to measure times between threshold crossings, and a delay counter to trigger a delayed state transition for the transistor bridge. One disclosed method embodiment comprises: receiving multiple phased alternating voltages; comparing each phased alternating voltage to a threshold; determining a period associated with voltage threshold crossings; triggering state transitions at some fraction of the period after each threshold crossing; and placing a transistor bridge into a configuration associated with a current state. For each state, the transistor bridge configuration is designed to couple phased alternating voltages to two output terminals in a sequence that produces a non-alternating voltage difference.

摘要： A downhole tool (100) for wellbore operations comprises a substantially tubular member (130) that is operably positionable in the wellbore and a rotation member (110) that is rotatably disposed within the substantially tubular member (130). The rotation member (110) has a passageway (112) through which objects may pass into the wellbore. The rotation member (110) rotates about an axis of rotation (x) that is substantially perpendicular to the longitudinal axis (y) of the substantially tubular member (130) in response to fluid flow through the passageway (112). The rotation member (110) has magnetic properties such that rotation of the rotation member (110) generates a magnetic field that produces useable power.

摘要： A multi-channel downhole telemetry system for enabling communication in a wellbore. The system includes a downhole transmitter operable to optically transmit a first data stream on a first optical channel and a second data stream on a second optical channel. A downhole receiver is operable to receive the first data stream and the second data stream. An optically transmissive fluid disposed in the wellbore provides a medium for the optical transmission of the first data stream and the second data stream between the downhole transmitter and the downhole receiver. The optically transmissive fluid contains suspended solids having refraction surfaces that scatter the optically transmitted data streams in the wellbore.
