三维地震勘探在湖泊沼泽地区的应用
|
摘要
介绍了在湖泊沼泽复杂地表条件下开展三维地震勘探的主要难点 ,并提出了针对性的技术措施 ,保证了野外数据采集和室内资料处理的质量。通过对三维地震勘探的野外数据采集、资料处理的总结以及勘探前后构造的对比 ,说明了三维地震在湖泊、沼泽地和柳条林这样的地表复杂地区取得了成功 ,并为今后复杂地区的三维煤田地震勘探工作提供了借鉴经验
This paper describes the main difficulties in conducting three dimensional seismic exploration under the complex surface condition of lakes and swamps, and puts forward corresponding technical measures for guaranteeing the quality of field data acquisition and in door data processing. Based on the summarization of field data acquisition and data processing as well as a comparison between the structures surveyed before and after the exploration, the paper points out that the three dimensional work carried out by the authors not only proves to be effective in such surface complex areas as lakes, swamps and willow forests, but also provides experience for future three dimensional coalfield seismic exploration work in complex areas.
