【摘要】 黄土塬地质条件非常复杂,是地震勘探中的困难区域。宁夏南部六盘山盆地属于典型黄土塬地貌的沉积盆地。该区勘探程度低,勘探潜力大,但该区表层沉积了巨厚黄土层、深层不同构造单元差异大,在采集上需克服地表和地下的双重影响。笔者详细分析了该区地质条件以及勘探难点,并结合该区的攻关实际资料和应用的新技术、新方法,总结出一套针对该区的地震采集技术系列,可以指导该区后期地震勘探工作。更多还原

【Abstract】 Loess plateau with very complex geological conditions is considered to be a world-class thorny problem.Liupanshan basin in southern Ningxia belongs to the typical loess tableland geomorphology and sedimentary basin,and its exploration is of low degree but has great potential.Geological conditions of the area is very complex with a great thickness of loess layer covering the surface,and deep conditions in different tectonic units are very different,so we must overcome the double impact of surface and underground in the seismic acquisition.In this paper,in combination with the data available and the application of new technologies and new methods,the authors analyzed the areas with different geological conditions and the difficulties in exploration and,on such a basis,summed up a series of seismic acquisition technologies with the purpose of guiding the exploration work in this area.更多还原
