摘　　要：以二连盆地齐哈日格图地区古河道砂岩型铀矿探测为例，开展地震技术探测古河道的试验研究，通过地震相、地震属性分析以及波阻抗反演技术，联合推测赛汉组上段古河道的平面展布情况，与实际地质资料进行对比分析可知，地震技术预测古河道具有较好的探测精度，是勘查古河道砂岩型铀矿的有效方法。This paper took the exploration of sandstone type uranium deposit of Qiharigetu site in Erlian Basin,as a case to detect the paleo valley by the seismic method.The distribution of paleo valley in the late Saihai age was deduced through analyzing the seismic facies,seismic attribute and inverting the impedance of target layer.The comparision between the results of seismic and geological data was carried out,which confirmed that the seismic technology discussed this paper was suitable for predicti the paleo valley in the research area.

关 键 词：赛汉组上段 古河道 地震相 波阻抗反演
