摘要
针对现有地震勘探震源存在问题和局限性,创新性地将金属丝电爆炸可控冲击波技术应用于地震勘探中,分析了金属丝电爆炸可控冲击波技术和产生原理.在掌握金属丝电爆炸可控冲击波技术作为地震勘探震源技术的特点和陕北沙漠地区进行现场激发试验的情况下,从理论分析和现场试验验证了金属丝电爆炸可控冲击波技术作为震源技术的可行性.通过对获取的数据进行定量分析,认为可控冲击波技术可作为一种新型震源技术,且在陕北沙漠区煤田地震勘探领域具备较好的应用发展前景.同时,通过总结试验中存在的问题,为下一步的改进提供方向.
Abstract
We evaluated the problems and limitations of existing seismic source,and innovatively applied wire electrical ex-plosion controllable shock wave technology to seismic exploration.The technology and principle of the controllable shock wave produced by wire electrical explosion are analyzed.Moreover,presenting the characteristics of wire electric explosion controlled shock wave technology as a seismic exploration source and the field excitation tests in the Shanbei desert,the fea-sibility of wire electrical explosion shock wave technology as a source technology is verified theoretically and experimentally.Based on the quantitative analysis of the acquired data,we believe that the controllable shock wave technique can be used as a new seismic source technique in the field of coalfield seismic exploration in the Shanbei desert.Finally,the existing prob-lems in the experiment are summarized,which provides the direction for further improvement.
