ABSTRACT:
Apparatus for steam cleaning subsurface liners in oil well bores and the like, comprising steam head means particularly designed and constructed for radially spreading a steam stream through a substantially constant area or volume from the stream to the proximity of the releasing jet area in order to maintain the steam at maximum heat upon the release thereof into the area being steam treated. The steam head may be initially introduced into the well bore by a tubing string, lowered to a position in the proximity of the liner by the tubing string, released from the tubing string and moved downwardly through the liner by a smaller tubing string, wire line or the like, and reciprocated within the liner by the smaller tubing string or wire line for cleaning of the liner.
