【摘要】 灰岩地区由于溶洞发育及岩性致密造成激发条件差,能量变化激烈等种种现象,因此在该领域开展石油地震勘探仍然属于世界性难题.如何在灰岩出露区取得良好地震资料,勘探工作者进行了各种各样的方法尝试,但仍未取得本质上的突破.在桂中灰岩岀露区开展针对性的方法攻关试验,创新施工方法,采用3线2炮宽线观测系统新技术、新方法取得了明显的勘探效果.更多还原

【Abstract】 It is still a world-class problem to carry out seismic operation in the limestone area due to the development of karst cave and lithologic density,which cause poor excited condition and great change of energy.To obtain good seismic data in such an exposed area of limestone,seismic exploration workers have been making a lot of effort,trying a variety of methods to solve this problem,but still not breakthrough in nature.In Middle Guangxi limestone area,such new methods as innovative operation technique,tackling key problems have been applied with new technology of observation system of three line two shots wide line,and the obvious effect of exploration was made.更多还原
