Abstract: This paper presents the fine interpretation of seismic horizon, analysis of regional tectonic setting, selection of reference datum, applied analysis of moldic method and residual thickness method, recovery of the paleo-relief and fine sculpture of the paleodrainage pattern of the Ordovician unconformity in Tazhong area. These could be as guidesfor well location arrangement.

Key words: Tazhong area, paleokarst, carbonate reservoir, horizon, datum, trend surface, paleo-relief recovery
