【摘要】 本文首先较系统地从理论上讨论了在高分辨率地震勘探中如何选取最佳药量及炸药耦合的问题 ;然后通过实际试验得出 ,在高分辨率勘探中应采用较大药量的激发方式以及为了改善炸药耦合条件应采用小井孔、闷井的措施 ;同时建议采用接收不同药量震源子波的方法 ,使其更接近地震勘探的实际情况 ,并使因素更为单一 ,更具可对比性。更多还原

【Abstract】 The problem of how to choose optimum charge and shooting coupling effect in high resolution seismic exploration is discussed theoretically. It is then pointed out that both major charge and minor shot hole which is plugged at top for good coupling should be used in high resolution seismic exploration. Authors suggest that different source wavelets of different charges may be taken respectively to meet actual condition in seismic exploration, and to have simple factors for good comparison.更多还原
