| 摘 要： | 基于地震同相轴空间二阶导数的曲率体属性作为一种新的地震属性在精细构造解释、裂缝预测、识别小尺度断层等方面发挥作用.在三维曲率体属性定义的基础上,采用一种三维离散倾角扫描算法,建立了一套无需人工解释层位便可直接从叠后地震数据体中提取多种曲率体属性的算法.利用建立的算法,通过编程实现,并在川西XC地区开展了基于曲率体属性的...

| Abstract: | Curvature attribute as a new technology,which was based on the second order derivative of seismic event,played an important role in fine structural interpretation,small scale fault identification and fracture prediction.Based on the definition of 3D volumetric curvature attribute,a 3D volumetric curvature attribute extraction algorithm based on discrete dip scanning was used to establish an algorithm for directly extracting volumetric curvature attribute from post-stack seismic data without manual interpret... |
