The electric spark source is a newly developed seismic exploration excitation instrument in recent years,which is more and more popular because of its advantages of safety,environmental protection,reusable and low cost,at present,it is mainly used in coalfield exploration,shallow exploration,seismic production and surface survey.With the solution of the instability of the high-power EDM source instrument,it can produce more than 200meters deep wells in the surface survey operation.At the same time,the crosstalk phenomenon can also be solved,which is also a development direction of seismic exploration stimulation.In the application of the electric spark source,there are certain requirements for the firing depth.From the existing data,it can be determined that the firing depth in water is below 9meters,on land,the determination should be based on shallow water,high-speed layer and actual experimental results,but not too shallow or ground guns will appear.Now the seismic exploration to the cost control is very strict,therefore is the efficient acquisition,here in the construction of the proposed rolling acquisition,can guarantee the construction efficiency,at the same time,it can ensure that the excitation sources do not interfere with each other and ensure the quality of seismic data,this will continue to improve with technological progress,and the second is through the combination of multiple electrical spark source simultaneously fired way to improve the single shot of energy.Finally,based on the above new technology,the future research and development direction of electrical spark source will be verified step by step in the future exploration,the technical potential will be stimulated in the future application.
