在滇、黔、桂山区采用弯线多次覆盖技术之后,地震资料的质量仍然没有显著的改善。这一方面是由于处理程序还不够完善,另一方面是在地震数据采集过程中还缺少相应的措施。因而在一个共反射点面元内,导致严重的道集时差存在。本文分析了组成道集时差的诸因素,并提出了消除这些影响因素的方法。 In Yunnan, Guizhou, Gui Shan area using multiple curve cover technology, the seismic data quality is still not significantly improved. This is partly due to inadequate processing procedures, on the other hand, lack of corresponding measures in the process of seismic data collection. Thus in a total reflection of the surface element, resulting in serious time lag exists. This paper analyzes the factors that make up the time difference of roadways and puts forward some ways to eliminate these factors.
