The seismic interpretation technology of the complicated fault block oil reservoir:a case history of the central anticlinal belt in Dongying sag

The clearer and larger structure reservoirs are almost ascertained along with the development of exploration and exploitation. Naturally, the stratigraphic and lithologic traps of the complicated subtle hydrocarbon reservoirs have been become exploration targets in each oil field. The complicated fault block reservoir is an important hydrocarbon reservoir, which account for considerable proportion in continental rift basin at present. But they are very difficult to distinguish and describe as their complicated and subtle in structure. In the paper, some technologies and their applications, such as seismic forward modeling and the seismic coherent analysis etc, are systematically summed up taking the central anticlinal belt in Dongying sag as example. We hope it can give a reference to related exploration in other regions.
