| 摘 要： | 山西黄土山区地形起伏较大，冲沟发育，黄土覆盖层厚，各种干扰波并存，激发困难，在进行三维地震勘探前，根据踏勘情况，选取不同岩性地段有代表性的点做试验工作，以确定野外施工参数。在保证野外资料质量的前提下，重点做好静校正、干扰波去除、叠后偏移等处理工作。并充分利用解释系统多种显示功能和自动拾取功能，从不同角度认识断层、陷落柱等地质现象。晋城某煤矿三维地震勘探实例验证了该项技术在复杂黄土山区的应用效果。

| Abstract: | There is distinct rising and falling in loess high country in Shanxi province, developed gullies and thick loess overburden make all sorts of disturbing waves coexisted resulted in difficuh shot. Before the 3D seismic prospecting, should make some testing in representative lithological points according to on-the-spot surveying for the determination of field operational parameters. To get done with statics, disturbing wave removing, poststack migration under the precondition of field data quality is guaranteed. Take full advantage of multiple displaying function and automatic taking up function of the interpretation system to find out geological phenomena of faults, subsided colunms etc. The 3D seismic prospecting living example of a coalmine in Jincheng has proved the application result of the teclmique used in eomplieated loess high country areas. |
