Device usable for offshore seismic prospection for receiving seismic signals and transmitting them to a central control and recording system

摘要

A two stage, decentralized device for transmitting seismic data information from seismic receivers of a seismic streamer to a central recorder on a ship, including a series of interconnected sections each having a plurality of seismic receivers distributed over it's length, seismic signal acquisition apparatus for digitizing and storing seismic signals coming from a group of seismic receivers to which a respective seismic signal acquisition apparatus is connected, central control and recording device on the ship and assembly of electronic modules each disposed in the vicinity of a seismic receiver and being capable of amplifying and filtering the seismic receiver signals.
