| 摘 要： | 在深部地质调查中，深反射地震剖面发挥了重要作用。一般情况下，在深反射地震调查的数据采集中，采用宽频带接收、适当长的记录长度和测线跨度、大动态范围的地震仪，有利于获取深陡倾斜界面反射波；采用较大的道间距、较长的接收排列和较高的覆盖次数进行数据采集，不但可获取较准确的波速信息、高信噪比的深层反射波，而且也可提高施工效率、降低成本。

| Abstract: | The deep reflection seismic profile plays an important role in deep geological survey.In common circumstances, the omployment of seismograph with wide frequency band reception,proper record fourth and suitable traverse span as well as large dynamic range will help to obtain reflection wave of deep stoeply-dipping interface; with the adoption of large chennel space, fairly lone reception arrangement and rather numerous cover times for data collection,one can not only obtain quite accurate information on wave velocity and deep reflection wave with high signal to noise ratio, but promote efficiemy and reduce costs as well. |
