Abstract：According to directional relation of NMO ve-locity in heterogeneous anisotropic media deduced by Grechka and Tsavankin,the paper predicted the fracture of media.Fist,the model observation in laboratory is carried out,which results showed the orientation variation of NMO velocity above the fractured media is ellipse,the direction of major axis represents the trends o fracture,the ratio of major and minor axes is proportion to the developed density of fracture.The method is used for limited azimuth 3-D seismic data in A work area of northern Tarim basin,the predicted fracture orientation is coincided with the results revealed by logging data, which achieved good applied results.This showed the feasibility of the method in identification of fractured direction and density.
