Abstract:
A drill pipe mountable wellbore cleaning tool apparatus includes a support sleeve that is mounted to a drill pipe joint in between the connector end portions of the drill pipe joint. Centralizers are attached to the opposing ends of the support sleeve and the support sleeve carries one or more debris cleaning tools in between the centralizers. At least one locking clamp is attached to the cylindrical portion next to a said centralizer, and prevents the support sleeve from moving longitudinally along the drill pipe joint.
