【摘要】 宁夏南部六盘山盆地属于典型黄土塬地貌的沉积盆地,该区表层沉积了巨厚黄土层,深层不同构造单元差异大,在地震数据采集上需克服地表和地下的双重影响。分析了该区地质条件以及勘探难点,结合实际资料并应用新技术和新方法,总结出一套针对该区的地震数据采集技术,可以指导该区后期地震勘探工作。更多还原

【Abstract】 Loess plateau in very complex geological conditions is considered to be a world-class problem. Liupanshan basin located in the south of Ningxia belongs to typical loess tableland geomorphology and sedimentary basin, the acquisition project is located in an area of low degree exploration, It has very large exploration potential. But the geological conditions of the area are very complex, specific feature is a thick layer of loess. Deep conditions in different tectonic units are very different, we must overcome the double impact of surface and underground in the collection. The paper analyzes the area with different geological conditions, and the difficulty of exploration. It sums up a set of seismic acquisition technology aiming at the area to guide the area exploration in combination with test data and application of new technologies, new methods更多还原
