高精度三维地震勘探在巨厚黄土地区的应用
|
摘要
巨厚黄土覆盖地区表浅层黄土结构疏松,对地震波吸收强烈,一直是三维地震勘探的难题。本院在甘肃某矿区,通过多种手段进行了相关试验、分析,最终选取适当的采集参数,获得了高信噪比的地震资料,采用初至折射静校正等一系列处理技术进行相关资料处理,取得了可喜的地质成果,为矿山安全生产奠定了基础。
The regions covered with thick loess,with loose surface structure,have a strong absorption of seismic waves and have always been a problem in three-dimensional seismic prospecting.Some corresponding experiments and analyses through various means in a mine of Ganshu Province have resulted in high signal-noise ratio seismic data with reasonable collecting parameters and these data have been treated with the refraction static correction of the primary waves with satisfying geological results,which may lay a foundation for the safe production of mines.
