Arrangement for developing and using thermal energy from heat conducting soil formations, has cavern provided with casing pipe in end area of constructed, lining depth drilling

摘要

The arrangement has a cavern (5) provided with a casing pipe (3) in an end area (4) of the constructed, lining depth drilling (2). The cavern is sealed with heat conducting materials (6) for surrounding soil formation (1). A sensor (7) opened downwards is arranged in the casing pipe in heat insulating manner reaching till the cavern, a hydraulic intersection (9) is arranged in sealing manner between casing pipe and sensor in an area (8) of minimum radiation losses of the soil heat conveyed against the surrounding soil formation.
