Abstract: A heating installation for hydrocarbon extraction pipes via a well linking the surface to an extraction zone, including a substantially cylindrical casing consolidating the drill hole, a hydrocarbon extraction method and method to enable a hot fluid to be made to circulate from the surface to the well zone to be heated. The injection method includes in the casing first thermally insulated heating tubing to inject the hot fluid from the surface to the required depth and second heating tubing surrounding the first tubing to bring the hot fluid towards the surface and the extraction method includes a pumping tubing surrounding the first and second heating tubing for the extraction of hydrocarbons.
