共深度点技术的广泛使用强调准确静校正的必要性。要想使共深度点迭加的优越性得以实现,一次反射的能量必须正确地排行。静校正量变化大的某些地区如不这样做,共深度点迭加是无用的。另一类地区,静校正量变化小,但在勘探地层圈闭的情况下,想得到控制反射波特征的高频成份,校正也是必要的。不论时间移动大小,静校正均可能成为重要的问题。使用过许多静校正技术。手工方法虽能提供好的效果,但太费人力,特别在高次复盖下资料数量很大,显然,需要计算机技术。
The widespread use of common depth points emphasizes the need for accurate static correction. To achieve the superiority of a total depth of points, the energy of a reflection must be correctly ranked. In some areas where the amount of static correction varies greatly, a total of depth points are useless. In other regions, the static correction is small, but in the case of stratigraphy exploration, it is necessary to obtain high-frequency components that control the characteristics of reflected waves. Static correction can be an important issue regardless of the time-to-move size. Many static correction techniques have been used. Although manual methods can provide good results, but too labor-intensive, especially in high-coverage under a large number of data, obviously, the need for computer technology.
