大陆科学钻探工程在世界上已实施30多年了,至今已有13个国家打出了近100口深浅不一的科学钻孔,但深度4000米以上的深孔仅有20口。其中,前苏联的科拉G-3钻孔深12262米,为当今世界第一超深孔;德国KTB钻孔深9100米,为世界第二超深孔。目前,正在全球实施的国际大陆科学钻探项目有10多项,主要研究领域包括板块构造、火山与地震活动、全球环境与气候
The Continental Scientific Drilling Project has been implemented in the world for more than 30 years. Up to now, 13 countries have drilled nearly 100 scientific drilling holes of varying depths, but only 20 deep holes with a depth of 4,000 meters or more are drilled. Among them, the former Soviet Union’s Cora G-3 drilling depth of 12262 meters, the world’s first ultra-deep hole; Germany KTB drilling depth of 9100 meters, the world’s second super deep hole. Currently, there are more than 10 International Continental Scientific Drilling Projects being implemented globally. The main research fields include plate tectonics, volcanic and seismic activity, global environment and climate.
