摘　　要：介绍了一种针对高速屏蔽层下弱反射层地震勘探方法———广角反射 (WAR) ,并且对广角反射地震波特征及其影响因素作了较为深入的讨论。通过对一个典型的地质模型正演模拟分析 ,得到了一些重要结论 ,这些结论对野外地震勘探与数据采集十分有用。A seismic survey method called wide angle reflection(WAR) used for exploration of weak reflectors below shielded layer of high velocity was described in this paper. The author analyses rather thoroughly the characteristics and influencing factors of seismic waves of WAR. Some important results, which are useful for seismic exploration and data acquisition, are concluded from forward modeling of a typical seismic model.
