The fracture-cave reservoir in Ordovician carbonates was formed by karstification in middle Paleozoic in Tahe Oil- field. It is one of the most complicated reservoirs in the world. Investigation of modern and ancient karstsand comprehensive interpretation on geological, well-logging and seismic data reveal that there are three zones （i. e. epikarst zone, vadose karst zone, and runoff karst zone） in the fracture-cave systems. Fracture-cave structure models were established for each zone to characterize the features and mechanism of fracture and cave in Ordovieian carbonates in Tahe Oilfield. The filling materials in the different zones of fracture-cave system were discussed. In conclusion, the study may help to describle and predict frac- ture-cave reservoir in karsted carbonates.
