| 英文摘要 | When using post-stack seismic data for characterizing faults and fractures, there are two different sets of seismic attributes available to choose, i.e. surface-shape-related and seismic discontinuity attributes. Depending on seismic data itself, each of them has its good points. Curvature falls into the former category and is powerful and popular in delineating faults and fractures. Based on our study, the curvature change rate is more relevant and sensitive to a faulted horizon. The new method employs the fitting of a cylindrical surface with arctan function as its directrix to characterize faults and fractures, including generatrix fitting and directrix fitting, both fittings are estimated in a least square sense. And then we calculate the curvature change rate of the directrix of the cylindrical surface. The applications of the new attribute demonstrate it can detect more subtle faults and fractures than traditional seismic attributes, especially for characterizing faults with small throws, and the results show high signal-to-noise ratio. |
