窄方位地震数据双平方根方程偏移方法探讨
|
摘要
简单回顾双平方根(DSR)方程偏移一般理论之后,介绍了适应偏移速度分析的角度域成像快速算法.针对地震勘探中窄方位三维地震数据成像问题,探讨了限定输入数据体或限定波场传播方向的DSR方程偏移方法.数值试验表明,共方位角偏移等DSR方程叠前深度偏移方法在盐体或礁体、古潜山等强横向变速地区具有很好的应用前景.
After reviewing the basic principle of the migration method based on double-square-root (DSR) equation, we introduce a fast angle domain imaging algorithm to facilitate migration velocity analysis. Then we discuss two approaches to migrate narrow azimuth seismic data, in which one has restriction to the input dataset, the other has limitation to the propagation direction of the seismic waves. The numerical tests show that, DSR equation migration methods such as common azimuth migration have a promising prospect in areas with strong variations of velocity, e.g., subsalt, reef and buried hill, etc.
