The reservoir of granite buried hill is well developed, wihout a layer distribution feature, and control factors for reservoir are complex, effected by the strong amplitude reflection of top basement, it is diffcult to make reservoir prediction by seismic attributes and inversion. The research is based on WBH(wide azimuth, broad frequency band, and high density) seismic data. Firstly, make azimuth division for the full azimuth seismic data, and optmize 355-40° to make reservoir prediction according to the characteristics of structure, fault, fracture. And then make spectrum decomposition for 355-40°seismic data, carry out single frequency volume optimization of 40Hz to predict the granite buried hill reservoir distribution. The reservoir development characteristics of newly drilled well W5 is consistent with the seismic prediction result, which conforms the reliability of GST spectrum decomposition for granite buried hill reservoir prediction.
