Abstract
A traction tool is operable with fluid flow from coiled tubing for use in a wellbore. The traction tool includes a mandrel, a driver, at least one piston, and a motor. The driver is rotatably disposed on the mandrel and can be movable between retracted and extended conditions when the at least one piston is actuated. The driver in the extended condition is configured to engage inside the wellbore. The piston is adjacent to the driver and is actuated by the fluid flow from the mandrel. The motor is also actuated by the fluid flow from the mandrel. The motor imparts rotation to the piston and the drive, which can be supported by bearings on the tool's mandrel. Tracks on the driver arranged at an angle transverse to a longitudinal axis of the tool allow the rotating driver to spiral inside the wellbore and advance the traction tool.
