Abstract：Fractured reservoir widely distributes in global area and exploration of fractured reservoir has important position in oil/gas exploration.Because of complex genesis of fracture and developed degree being controlled by multiple factors, although there is fracture information in seismic data, the seismic response caused by fracture factor is far more less than that by other geologic factors, so that it is difficult to use seismic data to identify the fracture.Nevertheless, since the seismic data have advantage of lateral continuity,the people still considered that the seismic method has irreplaceable role in fracture description and prediction.The paper briefly analyzed the difficulties and counter-measures when using seismic data to study fracture and summarized major techniques and methods using seismic data to study fracture in global area, which gives a reference to further develop the study at home.
