Method of seismic data processing |
| 摘要 |
The invention relates to a method of seismic data processing, wherein the data includes a set of seismic traces, with each trace including a signal that has been recorded by a sensor after having been propagated in a subsurface area, with the signal being defined by an amplitude as a function of time, including the steps of:
migration of data according to an initial time-velocity model,picking in the time-migrated data one or more event(s) corresponding to one or more subsurface reflector(s) so as to obtain facets locally approximating the event,kinematic demigration of the facets plotted so as to obtain simplified seismic data in the form of a set of facets and a set of attributes associated with the facets. |

1. A method of seismic data processing, wherein the data includes at least one set of seismic traces, with each trace including a signal recorded by a sensor after having been propagated in a subsurface area, with the signal being defined by an amplitude as a function of time, including the steps of:
migration of at least one set of seismic traces according to an initial time-velocity model; picking in the time-migrated data one or more event(s) corresponding to one or more subsurface reflector(s) so as to obtain facets locally approximating the respective event; performing kinematic demigration of the picked time-migrated facets so as to obtain processed seismic data comprising a set of facets and a set of attributes associated with the facets, wherein at least one set of attributes is used to produce one or more images representing the characteristics of said subsurface area.
