摘　　要：在开展区域性砂岩型铀矿矿产普查工作时,由于待普查区域地质、测井资料较少,给二维地震勘探砂体解释工作带来了一定的困难,这就需要综合使用多种方法来解决这一问题。地震正演模拟技术可通过岩性模型来模拟地下地层的波组响应特征,是解决岩性多解性的有效手段;地震属性分析技术可通过研究地震波几何形态、动力学特征及统计学特征相关的测量值,侧面反应地下地层岩性、孔隙度、不整合面及层序变化特征。结合上述两种技术各自之优点,对工作区宝龙山地带目的层砂体进行综合研究,经钻孔编录资料表明,该方法对砂体识别取得了较好的应用效果,可为其他地区地震资料解释工作提供参考。When the regional sandstone type uranium mineral survey is carried out,due to the few geological and logging data in the survey area,it has brought certain difficulties to the interpretation of sand body in two-dimensional seismic exploration,which requires the comprehensive use of various methods to solve this problem.Earthquake positive simulation technology can simulate the wave group response characteristics of the underground strata through the lithology model,which is an effective means to solve the multi-solution of lithology.Seismic attribute analysis technology can study the measurement values related to seismic wave geometric morphology,dynamic characteristics and statistical characteristics,and it can laterally reflect the changes in lithology,porosity,non-integrated surfaces and sequence of underground strata.For the combination of the advantages of the above two technologies,the sand body of the target layer in the Baolongshan area of the working area is comprehensively studied.Moreover,the drilling data shows that this method has achieved a good application effect on the identification of sand body,which can provide a reference for the interpretation of seismic data in other areas.
