摘　　要：研究工区位于鄂尔多斯盆地南部,构造上处于伊陕斜坡和渭北隆起的接壤部位,包括旬邑、宜君、黄陵、耀县等地区。工区地形起伏异常剧烈,表层结构极其复杂,有岩石出露的山体、河道砾石区以及黄土塬过渡带,地震资料的静校正问题突出、干扰波发育、目的层信噪比较低,资料处理难度较大。针对该区地震资料的特点和处理难点,通过层析静校正、叠前多域保幅去噪、叠前精细振幅处理、提高分辨率等技术的应用,实际资料处理取得较好效果。The Xunyi-Yijun block,which is located in the south of Ordos Basin,has some problems,such as extremely undulating topography of work area,extremely complex surface structure,exposed rock mountains,channel gravel area,transition zone of loess plateau,static correction problem of seismic data,developed disturbance wave,lower signal noise of target layer,bigger difficulties in data processing,and so on.In view of the characteristics of seismic data and the processing difficulties,main techniques have been applied,which include tomographic static correction,pre-stack multi-domain protection denoising,pre-stack fine amplitude processing,resolution improving,etc.And good results have been achieved in the practical data processing.
