| 摘要 |
<p>The invention relates to a method for seismic exploration, comprising the steps of controlling a plurality of sources so that they emit a plurality of seismic waves in a subsurface zone to be explored, each source successively occupying a plurality of emitter positions, - producing for each emission a signal representative of the emission, and recording the position of the source and the instant at which the emission starts, - continuously recording by means of seismic sensors the composite signals reflected by the medium in response to said emissions , and carrying out shot point migration , on the one hand, from a reflected wave field constituted of said composite signals and respective sensor positions, and on the other hand, from an incident wave field constituted of signals representative of the emissions, source positions and start emission instants, so as to obtain a seismic image.</p> |
