摘要： System for cableless bidirectional data transmission in a well for the extraction of formation fluids comprising: a plurality of rods connected to each other in succession so as to form a rod string, which extends from the surface to the bottom of the well, the rod string being associable with a plurality of sensors configured for continuously detecting a plurality of parameters relating to the fluids circulating in the well and to the rock formation surrounding the well and/or to safety devices or other remote-controlled well instrumentation; a plurality of communication modules applied at predefined distances along the rod string and configured for the transmission of signals from and towards the bottom of the well; each of the communication modules including at least one metal plate.
