<p>The invention relates to a process and a plant for the exploitation of the energy of geothermal water-bearing deposits, through a well wherein a heat exchanger is introduced and through a ground-surface plant. The plant for the exploitation of geothermal energy in blow-out producing wells comprises an underground part and a ground-surface part, where the underground part comprises a heat exchanger mounted inside the well to take over the heat from a geothermal water-bearing deposit, consisting of an internal tubing and an external tubing, the external tubing (B) having no thermal insulation and being closed at the lower end, while the internal tubing (D) is thermally insulated and open at the lower end, an annular space (a) being defined between the two tubings (B and D) wherethrough heating water circulates downwards, while through the space (c) inside the internal tubing (D) the heating water circulates upwards, and between the external tubing (B) and the well casing (A) there is defined another annular space (b) wherethrough the geothermal water circulates concomitantly with the water in the two tubings (B and D); the ground-surface part of the plant comprises a gas separator (N) connected to a catalytic gas heater (L), to a consumer and to a conduit for the return of water to the well casing (A), the separator (N) being further connected to some pumps (Q and T) and a storing tank (P).</p> |
