Seismic data processing and apparatus |
摘要 |
<p>There is a method of seismic data processing that includes receiving (1600) seismic data that includes a set of seismic traces, each trace including a signal recorded by a sensor after having been propagated in a subsurface area; migrating (1602) the seismic data according to a first velocity model; picking (1604) from the timemigrated seismic data one or more events corresponding to one or more subsurface reflectors so as to obtain a set of facets locally approximating the event; kinematic demigrating (1606) the picked set of facets so as to obtain simplified seismic data that includes the set of facets and a set of attributes associated with the set of facets; migrating (1608) the set of facets based on a second velocity model; and updating (1610) the initial velocity model based on an alignment of migrated points within the set of facets.</p> |
