摘　　要：21世纪以来,井下观测以日、美等国为首迅速进入"深钻井,多分量,宽频带"的发展时期,我国也紧随其后开始了井下综合观测技术的研究。本文介绍了10年来井下综合观测技术在世界各国大陆、大洋科学钻探工程中的应用,展示了各国井下综合观测技术上的成果,并分析比较了各种技术的特点,最后对深井高温高压环境、多测项集成技术和井下安装检测工艺等关键问题进行了分析和总结。在我国,井下综合观测仍属于技术创新项目,虽然第一批井下综合观测系统已成功研制出来,并在500m以内的钻孔中进行了小规模的实验,但成功经验较少,与技术领先的发达国家相比仍有不小的差距。In the 21st Century,led by the United States,Japan and other countries,borehole observation is entering a new high-speed development period with the characteristics of deep borehole,multi-component and broadband.In this paper,we introduced the progresses of borehole multi-component observation in continental and ocean scientific drilling programs among the word nations in the past ten years.Then,we presented and analyzed the technological achievements of borehole multi-component observation in the United States,Japan and Germany are presented.Finally,some key problems about high temperature and high pressure environment in deep boreholes,multi-component integrated technology,and instruments deployment and maintenance in boreholes are discussed.Currently,in China,the development of borehole multi-component observation is still in the beginning stage.Although some new instruments have been developed and deployed in some boreholes less than 500m,there is still a gap in technological level and experience between China and other developed countries.
