双平方根波动方程偏移速度分析
双平方根偏移 偏移速度分析 时移成像条件 剩余成像
2009/7/24
传统的剩余校正（RMO）偏移速度分析方法基于走时原理，在陡倾角和欠照明地区，因为不能得到充分的角度域信息而失效.本文将展示一种基于波场延拓理论的偏移速度分析方法，即波动方程偏移速度分析（WEMVA）.这种方法先利用成像优化方法获得剩余成像，再利用剩余成像反演剩余速度.此类方法继承了波动方程偏移方法的优点和缺点.波动方程偏移速度分析是一种线性反演方法，它要求对Born近似的展开序列作一阶截断.高阶...
中心回线装置是瞬变电磁勘探中最常用的装置之一.中心回线装置的视电阻率一般从回线中心点场的公式出发导出.在现场实际施工中，为提高工作效率，把发射回线中部三分之一的区域作为观测范围.通过对场分布特征的分析研究表明，与中心点相比，观测区边缘处的感应电动势数值偏离达15%~25%，这与广泛存在于华北型煤系中赋存深度为400~1000 m的陷落柱、导水小断层等引起的异常相比，已经不可忽略.大定源回线公式可以...
