井下甚宽频带地震仪研制内容与创新

Research and development of downhole very broadband seismograph and its innovation

  • 摘要: 井下甚宽频带地震观测能获取来自地球内部微弱的、丰富的、准确的宽频带地壳活动信息,包括地层微破裂、慢地震等,对地震学、地震预报和相关学科均有重要的科学研究意义和实际应用价值。研制具有我国自主知识产权的井下甚宽频带地震仪,并推进其工程化、产业化是地震观测仪器发展的重要方向之一。本文介绍了国家重点研发项目重大科学仪器设备开发专项 “井下甚宽频带地震仪的研制与应用开发” 的研究目标、研究内容及主要创新点。项目首次在国内外成功研制了可应用于2000 m深井观测的、完全自主知识产权的甚宽频带地震仪,并将在国家级重大项目中示范应用,打破了国外在井下甚宽频带地震观测的领先地位,促进了国内地震观测科学技术的发展。项目的主要进展将在项目专题中的4篇文章中分别进行介绍。

     

    Abstract: Downhole very broadband seismograph can obtain weak, rich and accurate broadband crust motion information, including formation microfracture and slow earthquake. It is one kind of critical instruments which is widely applied in seismology, earthquake prediction and related disciplines. Research and development of downhole very broadband seismograph with China independent intellectual property and promoting its engineering and industrialization is one of most important directions of seismic observation instruments. In this paper, we introduce the research objectives, research contents and main innovations of ‘Research and application development of downhole very broadband seismograph’, which is a project of National Key Foundation for Exploring Scientific Instrument of China National Key Research and Development Program. In this project, we successfully developed a very broadband seismograph product with China independent intellectual property that can be deployed at 2000 m depth boreholes and will be demonstratively applied in China national major projects. This marks the break-up of the leading position of foreign countries in the field of deep borehole very broadband seismic observation by China product. It will also promotes the development of China seismic observation technology. Besides this article, we will use other four articles in this column to introduce the details of main progress of this project.
