勘探区地处毛乌素沙漠西南边缘,表层多为干燥疏松的沙丘和黄土;浅层为沙土、卵石、砾石层,大部分地段不含水,均为松散沉积物。区内断层和褶皱发育,煤层埋藏深度与产状变化较大。针对该区表、浅层和深层复杂的地震地质条件,通过不断优化三维地震勘探设计,最终确定了野外数据采集观测系统及激发与接收参数,并在数据处理中,选择了合适的处理技术、处理参数及处理流程,获得了信噪比与分辨率较高的三维数据体,较好的完成了地质勘探任务。
The exploration area is located on the southwestern margin of the Mu Us Desert, with mostly dry and loose sand dunes and loess; shallow layers of sand, pebbles and gravel, most of which are free of water and are loose sediments. The faults and folds are developed in the area, and the depth and shape of the coal seam vary greatly. According to the seismic, geological and geological conditions of surface, shallow and deep complexion in this area, the field data acquisition observation system and excitation and reception parameters are finally determined by optimizing the 3D seismic exploration design. In the data processing, the appropriate processing technology is selected, Processing parameters and processing flow to obtain a three-dimensional data body with high signal-noise ratio and high resolution, and completed the task of geological exploration well.
