Method and apparatus for chemical treatment of subterranean well bores
This patent describes an inflatable well treatment tool suitable for insertion into a well through a well conduit disposed in a well bore. It includes a central tubular body assemblage connectable to a fluid supply conduit extending to the surface: the central tubular body assemblage defining a central fluid passage communicating with the fluid supply conduit: an outer tubular assemblage surrounding a medial portion of the central tubular body and cooperating therewith to define a generally annular fluid passage surrounding the central tubular body assemblage: resilient means urging the central tubular body assemblage downwardly relative to the outer tubular assemblage to a run-in position: the outer tubular assemblage including at least one angular elastomeric means expandable by pressured inflation fluid supplied through the annular fluid passage into sealing engagement with the well bore.
