Abstract
A downhole tool configured for inclusion in a drill string, typically as part of a bottom hole assembly. The downhole tool configured to improve passage of the drill string through a borehole. Additionally, the downhole tool is suitable for use in a method for improving passage of a drill string through a borehole.
Claims18
A downhole tool comprising:
- a tool housing having first and second ends and configured for attachment within a drill string;
- a fluid passageway providing fluid communication through the downhole tool, the fluid passageway extending from the first end to the second end of the downhole tool;
- a motor;
- a fluid flow control valve positioned within the fluid passageway, the fluid control valve movable between an open and a closed position, the fluid flow control valve configured to permit unmodulated flow of a fluid through the fluid passageway when in the open position;
- a pilot valve disposed in the housing and movable between an open position in which fluid flow is permitted therethrough and a closed position in which no fluid flow is permitted therethrough;
- a flow detection module programmed to provide an operating mode signal in response to sensed fluid flow characteristics of the fluid passing through the fluid passageway;
- and
- a motor control module in electronic communication with the flow detection module and the motor, the motor control module programmed to receive the operating mode signal and programmed to manage operation of the motor to control movement of the pilot valve between the open and closed positions based upon the operating mode signal, wherein the pilot valve is operable to move the flow control valve between the open and closed positions thereof.

A downhole tool comprising:
- a tool housing having first and second ends and configured for attachment within a drill string;
- a fluid passageway extending from the first end to the second end of the tool housing;
- a fluid flow control valve positioned within the fluid passageway and movable between an open and a closed position, the fluid flow control valve configured to permit unmodulated flow of a fluid through the fluid passageway when in the open position;
- a pilot valve operably associated with the fluid flow control valve and movable between an open position in which flow through the pilot valve is permitted to a closed position in which no flow is permitted through the pilot valve;
- a motor connected to the pilot valve;
- and
- a motor control module programmed to manage operation of the motor and thereby move the pilot valve between the open and closed positions thereof, wherein movement of the pilot valve between the open and closed positions thereof moves the fluid flow control valve between the open and closed positions thereof.

A downhole tool comprising:
- a tool housing having first and second ends and configured for attachment within a drill string;
- a fluid passageway extending from the first end to the second end of the downhole tool;
- a poppet valve positioned within the fluid passageway and movable between an open and a closed position in response to operation of the motor, the poppet valve configured to permit unmodulated flow of a fluid through the fluid passageway when in the open position;
- a pilot valve disposed in the tool housing and movable between an open position in which fluid flow is permitted therethrough and a closed position in which no fluid flow is permitted therethrough;
- a motor operable to move the pilot valve between open and closed positions;
- and
- a motor control programmed to manage operation of the motor to control movement of the pilot valve between the open and closed positions, wherein the pilot valve is operable to move the poppet valve between the open and closed positions thereof.
