摘　　要：近年来,广角反射作为地震勘探获得野外高质量地震数据的一种重要方法,愈来愈受到人们的关注。作者在本文中,通过对影响广角反射能量几个主要因素的研究与分析,提出了在广角反射方式下设计与优化观测系统的思路,以及怎样获得高质量地震资料的方法。通过正演模拟分析,得到了一些重要的结论,对野外地震数据的采集具有一定指导作用。Recently, more and more people focus on the wide angle reflection(WAR), which is a very important way of obtaining high quality seismic data by exploring in fields. In this paper, the authors put forward a way of the observation system design and optimization of WAR by studying and analyzing several key factors of affecting the WAR energy, and then, acquistion of the high quality seismic data. In addition, some important conclusions have been obtained through forward modeling.
