| 英文摘要 | VSP data can provide abundant information of seismic wave attenuation characteristics. This paper carries out forward calculations of zero-offset VSP synthetic record with attenuation. Considering reflection and refraction, the synthetic seismograms of layered attenuation models are generated based on Ganley's theory, which is fit for normal incident. Compared with the records without attenuation, the decrease of energy and frequency display the unelastic characteristics. We calculated the down-going and up-going wavefield with source location on the surface and underground. Unfortunately, the forward results showed that the arrival time shifted up in the down-going wavefield when the source was underground, which indicates problems in the original formula. We modify the transmission matrix and gain a corrected record, which corresponds with regular pattern. |
