陆上地震勘探中有关激发能量的几个问题

Problems Related to Exciting Energy in Land Seismic Exploration

激发药量和药性一直是陆上地震勘探研究的课题 ,根据弹性介质形变与地震波能量的关系 ,就弹性介质能量饱和问题进行了探讨。结合生产实际 ,提出了采用饱和激发、欠饱和激发、过饱和激发和最佳激发药量等概念 ,来判断或分析炸药震源的激发效果 ,以及饱和激发药量和最佳激发药量的确定方法和准则。

Induced charge and its property have been the basis of the relationships between elastic medium the main topics of land seismic exploration. On deformation and seismic wave energy, the problems of the elastic medium energy saturation are discussed. In combination with production practice,the concepts of saturation excitation, under saturation excitation and ov.er saturation excitation and optimal exciting charge are proposed for judging and analyzing the exciting effect of explosive source and establishing the criteria and method for saturation induced charge and optimal charge.
