| 摘 要： | 环县地区属于典型的巨厚黄土覆盖区,山大沟深,地形复杂。激发和接收条件极差,若采用常规直测线设计,野外施工非常困难,且地震勘探效果较差。面对山区、丘陵沟壑区的复杂地震地形条件,在精确计算接收点和激发点坐标的基础上,通过试验确定了弯曲测线折线转角大小、面元大小、叠加次数等主要参数,并利用共反射面元叠加原理进行资料处理,取得了良好的地质效果。

| Abstract: | The Huanxian area is situated in a relief complicated typical extra thick loess covered area with deep gullies and high mountains. Under the very poor shot and receiving conditions, if routine straight line is designed, field operation will be velT difficult, and seismic prospecting results poor. So that faced with complicated seismic relief condition, based on refined computation of receiving and shot point coordinates, to determine main parameters of slalom broken line interior angle range, surface element size and stacking fold through tests, carry out data processing using common-reflection surface element stacking principle, thus good geological effects obtained. |
