传统的三维地震勘探设计软件使用共中心点概念模型来分析面元属性，如褶皱、炮检距分布、方位分量和面元拖尾。该模型完全忽略了反射层结构、地下速度变化和复杂的射线路径几何形状。提出了一种结合三维正演模拟和反射点分析技术的新方法，为模拟的CRP数据生成理论面属性分布。对于简化的演示模型和墨西哥湾盐底辟模型，显示了CMP和模拟的CRP入库结果之间的比较。
Conventional 3-D seismic survey design software uses a CMP conceptual model to analyze bin attributes such as fold, offset distribution, azimuthal components and bin smear. This model completely ignores reflector structure, subsurface velocity variation and complex raypath geometry. A new approach is presented that combines 3D forward modeling and reflection point analysis techniques to produce theoretical area1 attribute distributions for the modeled CRP data. Comparisons between the CMP and modeled CRP binning results are shown for a simplified demonstration model and for a Gulf of Mexico salt diapir model.
