摘要: 针对2000 m深井观测的国家需求，应用 “解构与重构” 设计思路，共性赋能技术与地震技术深度融合的设计方法，对井下甚宽频带地震仪进行创新性总体设计；电磁兼容性、环境适应性与可靠性设计等定型技术设计；结构、功能与外壳的设计。测试和试运行结果表明，新研制的井下甚宽频带地震仪完全达到设计指标。Abstract: According to China national needs of 2000 m depth downhole seismic observation, using the design idea of ‘Deconstruction and Refactoring’ and the design method of deep integration of enabling technology and seismic technology, we innovatively carry out: ① the overall design of downhole very broadband seismograph; ② the design typification of its sub-systems of electromagnetic compatibility, environmental adaptability, and reliability; ③ the design of its components structure, function, and shell. The testing and trial operation results show that the newly developed downhole very broadband seismograph fully meets the design indexes.
