地震人机联作解释的二维射线追踪法正演模拟

2-D Ray Tracing Forward Modeling for Seismic Interactive Interpretation

二维射线追踪法正演模拟人机联作解释的思路是：根据实际地面地震资料及其初步解释结果，设计出一个解释模型，应用二维射线追踪法进行模拟计算，将结果与实际资料进行比较，依据两者之间的差异，修改模型，完成一次解释过程．利用计算机人机联作反复上述过程，直到模拟结果与实际资料在一定范围内吻合为止，最后一个解释模型就是对实际资料的解释结果．文中详细研究了二维射线追踪法正演模拟的主要内容，分析了人机联作解释的基本操作步骤；对地层模型进行正演模拟计算，结果表明该方法正确、可行．

Interactive interpretation for 2-D ray tracing forward modeling means that a model is designed from seismic data and its modeling data is computed by a ray tracing method. The modeling results are compared with real seismic data and the model is modified until they are consistent to some extent. Otherwise, this model is updated again.The final model is a expected interpretation.
