摘要
介绍了SEG起伏地表逆掩断层模型的特点,并以该模型数据为试验的原始地震数据,在理论模型速度和通过道集速度分析得到的速度2种条件下,分析对比了常规叠后时间偏移、水平地表叠前时间偏移、起伏地表叠前时间偏移和起伏地表叠前深度偏移的结果。
This paper introduced the features of SEG irregular topography overthrust fault model, and compared the results of conventional poststack time migration, horizontal surface prestack time migration, irregular topography prestack time migration, and irregular topography prestack depth migration on the model data with theoretical velocity and the velocity from velocity analysis on gathers.
