An operating well of a fluid storage reserve, includes an outer wall delimiting, with a central operating tubing of the well, an annular space in which is placed a protective sheath of an electrical link cable between a surface installation and elements arranged in the well. A device for the measurement of physical parameters includes at least one compact, removable, sealed measuring subassembly arranged in a housing in communication with the interior of the central tubing and at least one compact, sealed connecting subassembly integral with the central tubing of the well and arranged at least partially in the annular space in the vicinity of the protective sheath to be connected to the electrical link cable. The sealed measuring subassembly and the sealed connecting subassembly have plane contact surfaces, each associated with a half-transformer so as to form an inductive coupling between the measuring subassembly and the connecting subassembly. |
