| 摘要 |
The invention relates to a device for the in-situ extraction of a hydroca rbon-containing substance, while reducing the viscosity thereof, from an und erground deposit (103), wherein the device comprises at least one injection pipeline (101) extending in the deposit (103) and at least one production pi peline (102) leading out of the deposit (103), which together form a so-call ed well pair. The injection pipeline (101) and the production pipeline (102) each have a starting region (501, 502) extending above ground in some areas , and an active region (503, 504) connecting to the starting region (501, 50 2) inside the deposit. With the method according to the invention, during a heating phase hot steam is applied to the injection pipeline (101) and the p roduction pipeline (102), while during a production phase hot steam is appli ed only to the injection pipeline (101). Furthermore, the active region (503 ) of the injection pipeline (101) is additionally configured as an induction heater regarding the surrounding area in the deposit (103). The associated device is provided with appropriate means, wherein, for example, the well pa ir formed by the injection pipeline (101) and production pipeline (102) can be configured as electrodes.
