Prestack wave equation reverse-time migration of VSP data

Liu Qinglin Luo Yi  
Liu Qinglin and Luo Yi:Prestack wave equation reverse-time migra- tion of VSP data,OGP,24(3)1989:281~289 Based on wave equation theory,we can use finite difference me- thod to derive wave-field extrapolation formula,by which both wave- field modeling and migration can be made.The migration program VSP MIG that was developed using P-wave equation may be used to mig- rate both surface seismic data and VSP data.Besides,it may be applied to the migrations of P-wave data and P-SV wave data,in which case the original velocity model should be modified properly.The migrated image times for P-wave and P-SV wave respectively are absolutely equal.The migrations of upgoing P-wave and upgoing P-SV wave which have been separated can offer migrated P-wave section and mig- rated S-wave section.Thus,we can get more informations than from simultaneous migration of P-wave and S-wave data.
