Method of monitoring a subterranean zone su00ecsmica through simultaneous use of several sources of vibro su00ecsmicas

摘要

Invention patent: "method for the surveillance of an area su00ecsmica underground through the simultaneous use of several sources of vibro su00ecsmicas".The present invention relates to a method and a system for monitoring a subterranean zone (1), which includes the simultaneous use of several seismic vibrators.The system has, for example, several local units (Lu) that comprise each a vibrator (5), an antenna (2) of seismic sensors, a local unit of acquisition and processing (6),And a central unit (8) control and synchronization to run at the same time different vibrators by orthogonal signals.The local units (6) are adapted through specific processing operations, to isolate and reconstruct the seismograms corresponding to the contributions of the different vibrators.The invention is useful to monitor a deposit of hydrocarbons during production or a storage tank for the storage of gas, for example.
