| In view of the characteristics of carbonate reservoir with strong heterogeneity and complex plane distribution， based on the recognition that the distribution of carbonate reservoir is mainly controlled by large-scale unconformity surface， interlayer karst surface， fault system， reef-shoal facies belt and gypsum dolomite facies belt and other geological elements， the carbonate reservoir prediction technologies are developed with the integration of geology， logging and seismic on the basis of reservoir geological model and the calibration of reservoir logging identification and evaluation chart, with the identification of platform type/lithofacies, sequence boundary, karst reservoir, fault system, reef-shoal body and dolomite body as the core. These technologies have been applied to the prediction of the karst reservoir of Ordovician buried hill in west Lungu, inner fault-karst reservoir of Ordovician buried hill in Halahatang oilfield of Tarim Basin, the reef-shoal reservoir of Sinian-Cambrian, the crystalline dolomite reservoir of the Middle Permian Qixia Formation in Sichuan Basin, and dolomite weathering crust reservoir of the upper assemblage of Ordovician Majiagou Formation in Ordos Basin，and the coincidence rate of reservoir prediction increase by more than 20%. |
