Zusammenfassung:FIELD: oil geology, particularly to determine occurrence depths and relief structure of prospective geological horizons. ^ SUBSTANCE: method involves performing seismic exploration; drilling wells; determining reflection horizon seam depth on the base of drilling data; obtaining dependence of above seam depth as a function of relief altitude and determining interval velocity of upper non-uniform layer for following subsurface geologic imaging. ^ EFFECT: increased accuracy.
