1971年,在休斯敦举行的第四十一届SEG年会上,塞利斯和D·帕特尔特提出了一个地震模拟程序。不论倾角或速度变化如何重要,可以进行速度分析解释。在这种程序中,由模型计算出理论时间剖面和理论速度分析。将其结果与待解释的时间剖面和速度分析进行比较。对模型进行修改,直至理论结果和参考标准之间有足够的相关性为止。象这样一种解释对于每个地震反射面常需要5—10次迭代,也就是说对于整个模型
In 1971, at the forty-first SEG Annual Meeting in Houston, Sellis and D. Patel put forward a seismic simulation program. Regardless of how important a dip or speed change is, a speed analysis explanation can be made. In this procedure, theoretical time profiles and theoretical velocity analyzes are calculated from the model. The results are compared with the time profiles and velocity analysis to be explained. Modify the model until there is sufficient correlation between the theoretical result and the reference standard. An explanation like this often takes 5-10 iterations for each seismic reflection surface, which means that for the entire model
