ABSTRACT:
A steam generator lowered into a steam injection well for tertiary oil recovery has a conical bottom which cooperates with a conical support surface on a tube segment affixed to the casing of the well. The steam pipe passes through an opening at the apex of the conical support which centers the steam generator as it is lowered in place. The sealing is effected by a seal pressed by the weight of the steam generator between its conical bottom and the conical support surface.
