| 摘 要： | 根据弹性波动理论,分析了装药爆炸时冲击波转换成地震波的能量关系,对多级小药量垂向延时震源地震波能量叠加的原理进行了研究,建立了简化模型.试验结果表明,垂向延时叠加震源可在保证一定的信噪比的前提下,提高地震波的主频率,是高分辨率地震勘探的较理想的激发震源.

| Abstract: | The mai n method used in petroleum prospecting i s seismic exploration.Seismic dynamite s ource is one of important factors in sei smic data acquisition. Based on the theo ry of explosive dynamics and elastic mec hanics, the relation of shock wave energ y transformed earthquake wave is analyze d. The mechanism of shock wave superimpo sed amplitude in vertical direction is r aised and simplify model is given as wel l. Through experimentation, the results have shown that the main frequency of th e earthquake wave produced by the source is higher than ordinary seismic explosi ve columns. It is the ideally seismic so urce for high resolution seismic explora tion. |
