DEVICE AND METHOD FOR VELOCITY FUNCTION EXTRACTION FROM THE PHASE OF AMBIENT NOISE |
摘要 |
Methods and systems for deriving S-wave velocity information from the low- frequency content of ambient noise are described. The ambient noise can be collected on a dedicated record or on a production record associated with the receivers of a three-dimensional seismic survey. The methods and systems use one of a plurality of analysis models selected based on quality factors of the ambient noise data. The methods and systems analyze the data at a plurality of single frequencies then transform the velocity versus frequency data into velocity versus depth data. |
