| 摘要 |
The present invention provides a method for obtaining an attenuation model estimate for a vertical seismic profile, comprising: - receiving a vertical seismic profile (VSP) dataset; - building an estimate of the transfer function between pairs of depth levels of receivers of the VSP, based on the VSP dataset; - inputting information for modeling local interference and correcting the estimated transfer function; - choosing and fitting an effective attenuation law to the corrected transfer functions; - outputting an effective attenuation model; wherein said inputting information comprises measured well log and/or borehole information to model interference of the seismic wave field from interfaces near the receiver depth levels. The method further encompasses the outputting of an intrinsic attenuation model. |
