An installation for the in-situ extraction of a substance including hydrocarbons from an underground deposit is provided. The conductor and return conductor of the inductor lines are guided essentially vertically in the capping to the bottom of the deposit, at a small maximum lateral distance of 10 m compared to the length of the lines, but especially less than 5 m. Preferably, the inductor lines are guided horizontally in the deposit and are at different distances in certain areas. Furthermore, the electrical conductors and return conductors perpendicularly extending in the capping preferably combine to form a conductor pair. In this way, the conductor pair can be introduced into a single borehole which reaches into the reservoir and splits only once it has arrived in the reservoir. |

1. An installation for the in-situ extraction of a substance comprising hydrocarbons from an underground reservoir, the installation comprising:
a production pipeline leading out of the reservoir, through which the hydrocarbons are extracted; and a means for induction heating assigned to the production pipeline for heating of the production pipeline environment, comprising:
an electrical high-power generator outside of a capping and deposit,an electrical forward and return conductor, anda plurality of induction lines which are connected to the forward and return conductor, wherein the forward and return conductor are guided essentially vertically in the capping to a depth of the deposit and in comparison with a linear extent of the plurality of induction lines include a small lateral distance between them of maximally 10 m, and wherein the plurality of inductor lines run horizontally in the reservoir and include a predefined distance between the plurality of inductor lines which vary in the horizontal direction depending on geological conditions in the reservoir, wherein a first section is formed from an oscillator to the reservoir, a second section in the reservoir is formed wherein the plurality of inductor lines run horizontally and generally along side each other within the reservoir and as far as a salt injected region, and a third section comprising the salt-injected region within the reservoir is formed in an end region, wherein a different structure of the conductor is selected in each case in the individual sections, wherein in the first section, the forward and return conductor is a stranded or coaxial design, in the second section, individual insulated conductors are used for the plurality of inductor lines, and in the third section, non-insulated conductor ends are provided forming a plurality of electrodes in the salt-injected region. |
