| 摘 要： | 在油气勘探中，主要采用地震勘探。震源是地震勘探野外数据采集中的一个关键技术问题。该文依据爆炸动力学理论和弹性波动理论，分析地震波的振幅，频率与炸药量的关系，提出地震波垂向叠加的机理，给出垂向叠加震源的结构和有关试验结果。结果表明，该震源激发地震波的主频率比普通震源的有明显提高。

| Abstract: | The main method used in petroleum prospecting is seismic exploration. Seismic dynamite source is one of the key techniques in seismic data acquisition. Based on the theory of explosive dynamics and elastic mechanics, the relation of charges mass between frequency and amplitude of earthquake wave is analyzed. The mechanism of superimposed amplitude in vertical direction is presented,and the formation of the source and the experimental results concerned are given as well. The results showed that the main frequency of the earthquake wave produced by the source is higher obviously than ordinary seismic explosive columns. |
