摘要
本文以陕西陇县李家河勘查区煤炭资源详查二维地震勘探为实例,在不同地表条件,通过试验,确定了4种不同激发参数。同时,采用5个60Hz检波器串联组合方式接收,以克服近道面波及声波干扰。处理中静校正采用浮动基准面静校正方法,使用地表一致性反褶积技术,保证空间各地震反射道之间一致性。最终获得比较好的资料效果。
In the Loess Plateau area, two -dimensional seismic prospecting is often affected by complex con- ditions, low signal- to -noise ratio and poor quality, so it is very important to choose suitable parameters for different surface conditions. In this paper, the two -dimensional seismic prospecting for the coal resources in the Lijia River of Long County of t in Shanxi province is illustrated, in different surface conditions, 4 different excitation parameters were deternfined by experiments, and 5 - 60Hz geophone series were adopted to overcome the interference of shortcut surface and acoustic wave, and static correction method of floating datum plane was adopted in the process. Using surface consistent deconvolution technology to ensure the consistency of seismic reflection in space, the result obtained is better, which can effectively control the structural shape and coal seam development in the exploration area, and provide the basis for estimating coal resources.
