In order to build reliable seismic images, so to say to obtain the main result of seismic exploration work it is crucially important to determine distribution of seismic velocities in geological media. Special feature of anisotropic media, which can approximate most of geological media, is the incorrectness of determining vertical semi axes of ray velocity indicatrix based on onshore (and offshore) acquired seismic data. This is the reason for difficulties in interpretation of the velocity analysis results using onshore seismic data both for isotropic and anisotropic media. In order to provide more detailed understanding for distribution of seismic velocities in central, most prospective for petroleum exploration, part of Dnieper-Donets Basin (DDB) a velocity model incorporating well VSP and onshore seismic data was built. |
