Effect of Static Correction on Stack Velocity in Seismic Data Processing

地震数据处理中静校正对动校正速度的影响

In energy resource seismic prospecting, to best realize time difference correction of pre-stack tilted stratum, advance velocity analysis and overlay precision, present a sort of celerity realize pre-stack partial migration algorithm, called migration to zero offset ( MZO) algorithm.

在能源地震勘探中，为了更好地实现叠前倾斜地层的时差校正，提高速度分析和叠加的精度，提出了一种快速实现叠前部分偏移的算法，即零偏移距化（MZO）算法。

Full offset stack may reduce seismic resolution, because of lower frequency of far offset than that of near offset in raw seismic data, NMO stretching and velocity error.

受原始记录远道频率低于近道频率、动校拉伸、速度误差等因素的影响，满覆盖叠加降低了地震剖面的分辨率。

The relationship between stack velocity and interval velocity was deduced in depth.

Such high resolution can be seen in t_o time direction, particularly in stack velocity direction.

这种高分辨率下仅体现在l o时间方向上，而且在叠加速度方向上改善分辨率的效果更为显著。
