Considering the signal attenuation in deep well affects the use of the new wellbore anti-collision technology based on vibration wave, a kind of borehole seismic source designed. The distance among the risk wells can be identified by collecting the vibration signal produced by this borehole seismic source. The whole device includes energy storage and impact part, control part and auxiliary part. This borehole seismic source bases on the spring energy storage as basic principle. The impact hammer impacts the anvil as the impact institutions. The stuck points consist of arc fastener and arc grooves. The structure is simple and reliable. The function is easy to realize. The laboratory experiment results showed that this mechanical borehole seismic source can generate certain intensity and independent signals. The volume of the impact strength can fulfill the basis prevention warning of the monitoring the wellbore collision in deep layers.
