| 摘 要： | 在地震资料采集过程中,表层虚反射界面对地震波的激发效果影响较大，但也是确定炸药震源激发深度的重要因素之一.本文讨论了确定炸药震源距虚反射界面距离的有效方法，分析了复杂地表条件下虚反射界面对地震激发的影响，阐述了如何用之选择最佳激发井深，尽可能地减小由震源产生的各类次生干扰，获得频率响应较好的地震激发子波，以便采集到理想的地震资料.

| Abstract: | In the process of seismic data acquisition, surface ghost reflection interface will have great influence on the shooting effect of seismic wave; while in the meantime, it is also an important factor for determining the shooting depth of dynamite focus. In this paper, the method for determining the distance between dynamite focus to ghost reflection interface is discussed, and the influence of ghost reflection interface on seismic shooting is analyzed, demonstrating how to select the optimum well depth to minimized various secondary interference caused by focus, obtain relatively good seismic shooting wavelets and collect ideal seismic data. |
