METHOD FOR THE THERMAL TREATMENT OF AN UNDERGROUND OIL RESERVOIR
The invention relates to a method for thermal treatment of an underground oil reservoir (1), which has cracks (5) and into which at least one injection bore (2) has been sunk, wherein the injection bore (2) comprises perforation openings (32o) and perforation openings (32u) and two injection strands which are separate from each other, wherein the first injection strand (6) is connected via the perforation openings (32u) and the second injection strand (9) is connected via the perforation openings (32o) to the cracks (5) of the underground oil reservoir (1), wherein two formulations F1 and F2 (7, 8) are injected separately from each other through the two injection strands (6, 9) through the perforation openings (32o, 32u) into the cracks (5) of the underground oil reservoir (1) and mix in the underground oil reservoir (1) and enter into an exothermic reaction.
