Accurate description of complex fault block reservoir ——A case study of the central uplift in Dongying sag

The central uplift of Dongying sag, which has entered mature stage of exploration and development, is a typical complex graben structure. Accurate reservoir description must be conducted by use of various seismic and geological techniques in order to further tap the potential in this area. Combining with typical example, structure and reservoir description has been performed with emphasis on structure description process, seismic and geological analysis, and structure - controlled lithologic reservoir description. Several directions in description of complex fault block with high degree of prospecting are also put forward.
