摘要:
A system for forming a liner downhole within a well bore has a rig comprising a tool string driving mechanism and an aperture proximate an opening of a well bore. The system also has first and second tool string components and each component has a central bore disposed intermediate first and second tool joints of the component. The first tool joint of the first component is disposed proximate the aperture and the second tool joint of the second component. First and second resilient lining materials are disposed within the central bore of the first and second tool string components respectively. At least one lining material connecting mechanism is disposed proximate the aperture. The system also comprises at least one downhole dispenser that is adapted to direct a resilient continuous lining material against the well bore to form a liner.
