一口井中开始测量的深度点或者是深度被定为零的测量点。

The point in a well from which depth is measured.

其深度点技术仅意味着用不同的震源——检波器的分布形式多次重复每个反射观测。

The common-depth-point technique merely means the manifold repetition of each reflection observation with different source-detector geometry.

在叠前共深度点道集内各地震道的动、静校正误差很小的情况下，地震资料时间域水平叠加方法有较好的叠加结果。

The conventional stack method of seismic data gives quite good results when the errors of time corrections are small enough or the arrivals are near the same.
