Influence of ghost reflection interface on seismic shooting effect and its application

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.
