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.
Claims14
A method for reducing friction in a drill string as the drill string moves through a borehole, the method comprising:
- running the drill string into a borehole, the drill string including a friction reduction tool comprising:
- a first end configured for attachment within the drill string;
- a second end configured for attachment within the drill string;
- a fluid passageway providing fluid communication through the friction reduction tool, the fluid passageway extending from the first end to the second end of the friction reducing 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;
- a flow detection module programmed to provide a plurality of operating mode signals;
- 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 signals;
- flowing a fluid through the friction reduction tool;
- sensing vibrations generated by the fluid flowing through friction reduction tool with the flow detection module;
- selecting one of the plurality of operating mode signals in response to the sensed vibrations;
- transmitting the selected operating mode signal to the motor control module;
- and
- operating the fluid control valve in accordance with the selected operating mode to control fluid flow through the friction reduction tool.

A downhole tool comprising:
- a tool housing defining a fluid passageway therethrough extending from a first to a second end of the tool housing;
- a fluid flow control valve movable between open and closed positions in the tool housing, the flow control valve having a plurality of radial exit ports defined therein;
- a pilot valve positioned in the tool housing and rotatable relative to the fluid flow control valve;
- and
- a motor connected to the pilot valve and operable to rotate the pilot valve at a predetermined rate of rotation in response to an operating mode signal produced by a flow detection module in the tool housing, wherein rotation of the pilot valve opens and closes the radial exit ports at the predetermined rate to open and close the fluid flow control valve in a predetermined timing sequence.
