深井地球物理观测的最新进展与中国大陆科学钻探长期观测
|
摘要
深井地震与地球物理观测(Borehole Seismology)是21世纪的一项崭新的高科技项目.其目的是为了解决地球的表面效应和人类社会高度发展的城市化、工业化、现代化带来的噪音干扰,提高信噪比,推进现代地球物理观测与研究.随着地球系统科学的深入以及解决环境、资源、地震灾害预报等问题的需求,近年来世界大陆科学钻探以及在钻孔深井内进行的地球物理长期观测得到了飞速发展,取得了高精度的观测研究成果.中国大陆科学钻探长期观测在前期工作基础上,已经启动并正在构建我国第一个无地面干扰的深井地震、地球物理长期观测站,为实现我国的"入地"科学计划,开创我国21世纪地球科学观测研究的新局面作出贡献.
The borehole Seismology is a new high-tech project in the 21~(st)century.It is a significant for the development of the geoscience study to solve the earth surface effect and to improve ratio of signal to noise in the heavily ambient noise with speed industrialization and citifying.Observation in the deep borehole is an available way to restrain the noise.Recently,in order to solve environment,resources and earthquake predict problems,the scientific drilling and the long-term multicomponent geophysical observations in the deep borehole have been speed developed. Numbers of achievements of observation and study have been reported.Based on the project of the Chinese Continent Scientific drilling(CCSD),a new CCSD observation in the deep borehole in Donghai,Jiangsu starts and the bright future for the deep borehole geophysical observation is clarified.The long-tem borehole observatory in Donghai is going to be built and be the first noiseless multi-geophyical observatory in China.The observatory is the significant study base to realize inner earth.The deep borehole observation is going to rich the knowledge on geoscience and benefit the resource prospect,environment protection and earthquake predict.
