摘　　要：以陕西关中巨厚黄土塬区三维地震勘探实例,分析了黄土塬区地震勘探存在的技术难点,阐述了工作中采取的技术对策。通过大量野外试验,确定了合适的数据采集方法,获得了信噪比较高的原始资料。通过资料处理及解释工作,获得了丰富的地质成果,达到了预期效果。The drought loess tableland is a difficult area to prospect by seismic technology. Based on the application of 3-D seismic prospecting in thick loess tableland, the paper analyzed the difficult points of this technology applied in the area, expatiated the countermeasures. According to a lot of experiments in the field, we chosed a suitable method to gather data and get original data of high signal to noise ratio. By careful data processing and data interpretation, rich geological findings was got.
