Abstract：Based on the 3D seismic data in Wudong Area of Hailar Basin,the fracture reservoir was predicted in this area by using several methods,such as tectonic stress field analysis,pre-stack seismic attribute azimuth anisotropy analysis,post-stack seismic attenuation attribute analysis and so on.The qualitative prediction for the macroscopic fracture development zone was conducted by using post-stack fracture attribute method and the tectonic stress field analysis method,it was found out in the study that the fracture orientation is mainly in NNW and NEE direction,the fracture density was quantitatively predicted by using pre-stack seismic attribute azimuth anisotropy analysis method.
