摘要： An apparatus for flowing a tool string along a wellbore tubular may include a flow restrictor having a diametrically expanded position and a diametrically retracted position. The flow restrictor may include at least one sealing element that sealingly engages the wellbore tubular when in the diametrically expanded position. The apparatus also includes an actuator configured to move the at least one sealing element to at least a position intermediate of the open and the closed position. The actuator may be responsive to a control signal that is generated locally or transmitted from a remote location.

摘要： An apparatus for flowing a tool string along a wellbore tubular includes a flow restrictor having a diametrically expanded position and a diametrically retracted position. The flow restrictor sealingly engages the wellbore tubular when in the diametrically expanded position. The apparatus also includes a joint connected to the flow restrictor. The joint actuates the flow restrictor between the expanded position to the retracted position while moving between an open and a closed position.

摘要： An apparatus for use downhole is disclosed that, in one configuration includes a downhole tool configured to operate in an active position and an inactive position and an actuation device, which may include a control unit. The apparatus includes a telemetry unit that sends a first pattern recognition signal to the control unit to move the tool into the active position and a second pattern recognition signal to move the tool into the inactive position. The apparatus may be used for drilling a subterranean formation and include a tubular body and one or more extendable features, each positionally coupled to a track of the tubular body, and a drilling fluid flow path extending through a bore of the tubular body for conducting drilling fluid therethrough. A push sleeve is disposed within the tubular body and coupled to the one or more features. A valve assembly is disposed within the tubular body and configured to control the flow of the drilling fluid into an annular chamber in communication with the push sleeve; the valve assembly comprising a mechanically operated valve and/or an electronically operated valve. Other embodiments, including methods of operation, are provided.
