Based on wide-azimuth seismic data and drilling data，the seismic comprehensive prediction of Ordovician
heterogeneous carbonate fracture-carst reservoir was conducted in the top of Nanpu2 buried-hill.On the basis of
seismic data amplitude-preservation processing，the surface layer and fracture pattern of Nanpu2 buried-hill is
identified by fine structure interpretation.Meanwhile，the P-wave azimuth anisotropy analysis technique is used to
carry out pre-stack fracture prediction and curvature attribute is adopted to carry out post-stack fracture
prediction.Moreover，post-stack attenuation gradient is utilized to detect the distribution of caves.By comparing
the pre-stack and post-stack prediction results，combined with FMI imaging logging interpretation result and
drilling data，we proved the correctness of our research clue and the effectiveness of the prediction methods.The
comprehensive prediction results provide a basis for identifying the potential target area of Ordovician carbonate
reservoir in the Nanpu2 buried-hill.
