苏北唐港地区地震宽线试验和效果

WIDE LINE EXPERIMENT AND ITS EFFECT IN TANG-GANG REGION, NORTH JIANGSU

本文通过对一个地区的地震宽线观测的试验研究,把宽线资料与常规资料作对比分析,肯定了宽线能更大地提高时间剖面质量.同时,通过宽线资料的空间解释,识别来自不同射线平面的反射,确定这些反射的确切位置和产状,有利于解决复杂地质构造问题.本文还叙述了宽线剖面野外工作方法和施工及资料处理中的注意事项.

By contrast the wide line data to the routine ones obtained in the same region, it was unquestionably made certain that the wide line time sections are much better in quality than that obtained by conventional means.By way of the explanation of the wide line data in space, reflections from different ray-path planes could be identified and the right space positions of these reflectors could thus be determined. For solving the complex geological structural problems, the wide line technique has been proved to be very useful.Additionally, the field work of wide line profiling, its points for attention and the matters needing attention in data processing were also described.
