从3-D地震体绘制交会图属性的能力允许地震学家识别和保证详细检查的3-D体的高等级子集。在振幅随炮检距变化（AVO）交会图的情况下，地震属性是从CDP数据导出的。交会图是AVO分析中的一个基本过程，正如它在岩石物理分析中一样。理解属性的复杂性和选择对于成功的AVO分析和改进地震解释是必不可少的。利用毕奥‐Gassmann方程对从测井曲线导出的模拟地震数据进行AVO交会，为理解交会时流体替代对AVO属性相互作用的影响提供了基础。有了这些基于模型的理解，改进的多属性解释过程可以从地震体的AVO交会图开始。
The ability to crossplot attributes from a 3-D seismic volume permits a geophysicist to identify and high grade subsets of the 3-D volume that warrant detailed inspection. In the case of amplitude‐variation‐with‐offset (AVO) crossplotting, the seismic attributes are derived from CDP data. Crossplotting has become a fundamental process in AVO analysis, just as it is in petrophysical analysis. Comprehending the intricacies and selection of attributes is essential for successful AVO analysis and improved seismic interpretation. AVO crossplotting of modeled seismic data derived from well logs with the Biot‐Gassmann equations provides a basis for understanding fluid substitution effects on AVO attribute interactions when crossplotting. With these model‐based understandings, improved multi‐attribute interpretation processes can commence with AVO crossplotting of seismic volumes.
