Based on the full azimuthal and high density seismic data in ZG area of Tazhong district in Tarim Basin, the authors detected fractures through the P-wave azimuthal anisotropy with prestack seismic data in OVT domain.After migration in OVT domain, the seismic data which possess azimuth and offset information, are suitable for fast prediction of fractures and hence avoid waste of time.The authors examined different offset ranges and azimuths and the alterable seismic domain and then chose the offset in the range of 100~5500 m and 6 azimuth to predict the fracture.To analyze the relative impendence inversion of every azimuthal datum, the authors determined the fracture orientation and fracture density of carbonate reservoirs in Yingshan Formation.The results are largely consistent with the practical drill hole and can guide the study of well deployment, connectivity of cave-fracture and design of horizontal well.
