Abstract:
A wellbore cleaning device comprises a tubular section, a helical scratcher mounted thereon. The helical scratcher contains flexible wires characterized in that the helical scratcher is able to rotate axially to the tubular section when a fluid flows axially to the tubular section. A method for using the device comprises placing the device into the wellbore; allowing the fluid flowing axially to the wellbore wall to rotate the scratcher; removing a deposit at wellbore wall; and leaving a cleaned wellbore wall.
