倾斜叠加空间与几种地球物理法相比,具有许多分解上的优点。反演倾斜叠加的变换使我们有可能利用这些有利条件,并且有可能在进一步的处理中回复到常规的时间距空间(t—x)。著名的正演倾斜叠加变换法可把时距(t—x)空间中的一组地震道转换成截距时间视倾角(t—p)空间中的另一组地震道。这种变换在沿视倾角测线扫描(每道p毫秒)时,可求出(t—x)道的总和。时间τ就是这条测线在参考道上的截距。这种变换可以在叠加道道集或叠加道组的基础上进行。
Tilting overlay space has many advantages over several geophysical methods. The inversion of the tilted overlay makes it possible to take advantage of these advantages and is likely to return to the conventional time-space (t-x) for further processing. Renowned forward-tilted overlay transformations transform a set of traces in time-space (t-x) space into another set of traces in intercept time dip (t-p) space. This transformation finds the sum of (t-x) tracks as the line-of-sight line scan (every p millisecond) is done. The time τ is the intercept of the line at the reference track. This transformation can be based on overlay or overlay groups.
