Abstract: Tahe oilfield's carbonate reservoir is buried deeply with normal depth over -5300m. The dominated system of carbonate fractures and corrosive caverns and serious heterogeneity in plane and vertical results in difficulty for transverse prediction of the reservoir distribution. This paper correlated and analyzed a lot of drilling,coring, well logging and seismic data, discussed and developed a geophysical recognizing model for extra-deep carbonate reservoirs, which gives a great support to exploration and development of Tahe oilfield by means of such a more practical model for carbonate reservoir recognition and prediction.

Key words: Tahe oilfield, extra deep carbonated reservoir, prediction, geophysical recognition model, well logging, seismic
