PROCESS FOR IMPROVING THE EXTRACTION OF RAW OIL AND INSTALLATION USING SAID METHOD

摘要

The invention relates to a method for improving a hydrocarbon extraction installation 1, through a borehole connecting the surface to a deposit 5, comprising a substantially cylindrical envelope 6 consolidating said borehole and an extraction pipe 8 housed within the envelope 6.The installation comprises a boiler 14, a pipe 12 thermally insulated to send and circulate the hot fluid from the surface to the deposit 5. The installation also comprises an extraction pipe 8 allowing the rise of the mixture of hot fluid and hydrocarbons.
