DISPOSITIF POUR ELEVER LA TEMPERATURE D'UNE FORMATION GEOLOGIQUE TRAVERSEE PAR UN PUITS

摘要

The invention relates to an arrangement for increasing the temperature of a geological formation (1) penetrated by a bore hole (2). The arrangement utilises devices (4) for feeding a heat transfer fluid into the geological formation (1), and heating devices for the fluid which are connected to an electric power source (6), the heating devices for the fluid being fastened to the free end of a line (3) which is connected to the devices (4) for feeding in the fluid. The arrangement can be used to initiate an in-situ combustion in methods for extracting hydrocarbons, for the gasification of coal, etc., or to stimulate the production of a viscous product contained in the geological formation. <IMAGE>
