Abstract
The fractured reservoirs will inevitably become a significant field as the focuses of oil and gas exploitation are gradually shifted from shallow exploitation to deep one and from conventional reservoirs to unconventional ones. This paper has done a lot of study to do with the prestack seismic gathers in the HSX region, such as processing of the prestack preserved amplitude, stacking of the sub-azimuth, migration and forward modeling of the fracture segments and fracture prediction of structural causes based on the analysis of the stress fields. The paper has also detected anisotropic fractures according to the prestack azimuth AVO and QVO characteristics in this region and finally predicted the direction and density map of fractures in the HSX region.
