摘　　要：地震勘探激发技术的研究表明,激发是高分辨采集技术研究的重点。基于爆炸理论,对炸药的药型、药柱的形状、爆速以及雷管的激发位置进行研究,克服以往小药量激发获高频率的思维定势,形成多井组合、大药量激发获得高频资料的新思维。实践表明,在江汉地区使用长柱状高爆速炸药,将雷管置于长柱状炸药的顶部,采用双井9kg的大药量分装组合激发方式,可获得高分辨率的地震资料。Exploration shooting is the key point of research on high--resolution acquisition technology. On the basis of explosion theory, this paper studies explosive types, grain forms, explosive velocity and exploder＇s shooting position, hoping to overcome former thinking set of obtaining high frequency with small charge shooting and form new thinking of obtaining high--frequency data with multi--well group and large charge shooting. Practice indicates that high--frequency seismic data can be obtained in Jianghan area by using rod--like high velocity explosives with the exploder on their top and choosing array shooting mode with dual--well subpackage of 9kg explosive quantity.
