Abstract
In one aspect an apparatus for performing a downhole operation is disclosed that in one non-limiting embodiment may include a downhole tool that contains a hydraulically-operated motor and a flow control device that in one position allows a fluid to pass through the motor while preventing the fluid to flow to the motor and in another position allows the fluid to flow to the motor to operate the motor.
Claims20
A downhole tool for performing an operation in a wellbore, comprising:
- a fluid-operated motor having a rotor inside a stator, the rotor having a fluid flow path therethrough;
- and
- a flow control device above the rotor that in a first position allows a fluid supplied to the motor to pass to the fluid flow path in the rotor and blocks the fluid from flowing to the motor to prevent the motor from rotating and in a second position allows the fluid to flow to the motor to cause the motor to rotate.
An apparatus for performing a downhole operation, comprising:
- a tool that includes a hydraulically-operated motor;
- and
- a flow control device that in one position allows a fluid to pass through the motor while preventing the fluid to flow to the motor and in another position allows the fluid to flow to the motor to operate the motor.
The apparatus of claim further comprising:
- a drill bit operated by the motor;
- a whipstock below the drill bit;
- an anchor below the whipstock;
- and
- and a fluid supply unit that supplies a fluid the flow control device, wherein the anchor is settable by the fluid flowing through the motor and the drill bit is operable by the fluid flowing to the motor.
A method of performing an operation in a wellbore, comprising:
- conveying a downhole tool in the wellbore, the tool including a fluid-operated motor having a rotor inside a stator, the rotor having a fluid flow path therethrough;
- flowing a fluid through the rotor while blocking flow of the fluid to the motor to prevent the rotor from rotating;
- performing an operation in the wellbore using the fluid flowing through the rotor;
- and
- flowing the fluid to the motor to rotate the rotor.
