SEISMIC DATA ACQUISITION SYSTEM USING ACQUISITION STATIONS ESTABLISHED ON THE OCEAN FLOOR

摘要

- donnu00e9es.sismiques acquisition system by means of radio stationsacquisitionput on the bottom of a body of water.the system includes acquisition stations (dsau) with aarrow shapes adapted to work in the background and combine severalreceiversseismic with the underlying formation, and a proof for the modules.electronic data acquisition and communication. these stationsacquisition(dsau) are laid down in the bottom of the force of gravity.severalrelay buoys (bcr) are positioned on the surface, each with a modulegps positioning, a radio link with a central station (ccru), ashipfor example, modules of acoustic communication with stationsthe acquisition of(dsau) used both to determine the position of the stations.in relation to therelay buoys and to exchange data and control data.seismicdata of operation or seismic traces acquired iftheappropriate conditions).- applications for prospecting and seismic monitoring of trainingunderground.
