Abstract: The prediction of fracture-developed area is one of the most important missions for exploration of reservoir of fractured buried hill. A fracture predicted flow based on diffracted wave attribute is proposed, and the principal component analysis algorithm is used to extract diffraction information from seismic field. Meanwhile, via forward modeling, it is the practicability that the flow prove and it's indicate that diffraction attributes can descript the fracture distribution effectively. Finally, the fracture predicted flow is proved feasibility and accuracy to descript the character of fractured reservoir in practice.
