世界上在居民区内,真正的直地震测线的例子廖廖无几。甚至在人口稀少的定居地区的地形和水网区域经常要求测线弯曲或不规则的组合间距。沿道路用非炸药震源工作提供了一般问題的典型例子。很多人都意识到了问题的各个方面,通常考虑到在最终迭加剖面上,信号的品质减低。然而通常看不清,并忽视了这些问题。尚未充分了解测线的偏差对速度和剩余静校正分析的更细致的影响,然而他们通常比简单的信号的品质降低更为重要。 There are only a few examples of true straight seismic lines in the world in residential areas. Even curved or irregular line spacing is often required in the topography and water network areas of sparsely populated settlements. Working along roads with non-explosive sources provides a classic example of a general problem. Many people are aware of all aspects of the problem, often considering the degradation of the signal quality at the final stacking profile. However, they are usually invisible and overlooked. The effects of line deviations on speed and residual statics analysis have not been fully understood yet, but they are often more important than the quality of simple signals.
