摘要
鄂尔多斯盆地矿产资源丰富,是我国陆上第二大沉积盆地,加快该盆地矿产资源的勘探工作,对推进我国中西部能源基地建设,缓解我国当前能源危机问题有非常重要的现实意义。但是,由于该地区大部分处于黄土高原,地表条件复杂,表层岩性变化剧烈,地震勘探一直是难点。本文以姬塬地区为例,针对地震勘探难点,对黄土塬变化多样的地表地震及复杂的地下地质条件进行了综合分析,综合应用层析静校正、时空转换、反褶积等复杂地区地震资料处理技术,取得了较好的处理效果,提高了信噪比,可以为类似条件的地震资料处理提供借鉴。
Ordos Basin is the second largest of China＇s onshore sedimentary basins and the rich mineral resources in Ordos Basin make it is very important. The exploration of mineral resources in the basin is conducive to China＇s economic development. However, since many objective factors, for example, most of the area in the Loess Plateau, surface condition is very complex, very dramatic changes in the surface, seismic exploration has been difficult. This paper is based on some studies in Jiyuan area and discuss the complex subsurface geological conditions, Changes in a variety of surface seismic in the region of the Loess Plateau. The seismic data processing technology in complex areas, such as tomostatics, space conversion, deconvolution and so on, is helpful to improving the signal to noise ratio of seismic data and achieving good treatment effect. This result can provide a reference for dealing with similar conditions.
