【摘要】 通过大量的文献调研,系统地总结了地震采集的最新进展。这里扼要介绍了照明度分析采集设计的核心思想,说明了Teepee技术,同时给出了观测系统优化和宽方位采集技术的新进展。对于其中的激发、接收部分,则主要介绍了几项实用技术。针对地震仪器的发展过程以及应用现状,重点介绍了基于MEMS(Micro Electro Mechanical Systems)的数字检波器的基本原理、性能指标和优缺点,最后对地震采集技术的发展前景进行了展望。更多还原

【Abstract】 Through extensive investigation,the progress of seismic acquisition is systematically summarized.At first,the paper introduces a method of acquisition which based on the technology of illumination,and describes the Teepee technology.Then process of the 3D survey design optimization and wide-azimuth seismic acquisition are recommend.For seismic explosion and reception,we introduce several main practical techniques.This paper also concerns the development and application of seismic instrument,especially introduces its fundamental principles,performance and relative merits of the digital geophones which is based on the technology of MEMS.Finally,the future of seismic acquisition is discussed.更多还原
