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. In this paper, we compare the wide-line data with the conventional data by testing the wide-line seismic observation in a region and confirm that the wide-line can greatly improve the quality of the time profile.At the same time, through the spatial interpretation of wide-line data, The reflection of the ray plane and the exact location and occurrence of these reflections are helpful to solve the complicated geological structure problems.This paper also describes the fieldwork method and considerations in construction and data processing of wide-line profile.
