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。
The Ordos Basin is rich in mineral resources and is the second largest sedimentary basin on land in China. It is of great practical significance to speed up the exploration of mineral resources in the basin and to promote the construction of the energy base in central and western China to ease the current energy crisis in our country. However, since most of the area is in the Loess Plateau, the surface conditions are complex and the surface lithology changes drastically. It is always a difficult point to carry out seismic exploration. Taking the Jiyuan area as an example, aiming at the difficulties in seismic exploration, this paper analyzes the varied surface earthquakes and the complex underground geological conditions in the loess plateau. By comprehensively applying the seismic data in such complicated areas as tomostasis, space-time transformation and deconvolution Processing technology has been achieved better processing results, improve the signal to noise ratio, can provide reference for similar conditions of seismic data processing.
