联邦德国大陆深孔计划(KTB)是一项基础研究项目,用以考察地壳深部的物理与化学状况及形成过程,以便对大陆内部构造演化动力学有更深的了解.科学研究的目的包括起源和地球物理异常的原因以及现场的物理与化学状况,流体体系与对地壳的影响,地球物理构造与地壳演化以及在地球深部实验设施的安装.1956年选定钻探地点在巴伐利亚州东北部的上普法尔茨地区,邻近文迪施琛巴赭镇(Windischenbach),在波希米亚地块的西翼.现场位于Variscan山脉Saxothuringian和Moldanubian地区连接处的右侧.根据物探勘测预期可以遇到一处严重构造的地壳.1987年9一口3000-5000米深的要全部取心的导孔将开钻,钻进时间一直延续到1988年中,继之而来的是用大约一年时间作试验与钻孔测量.按当前规划,超深孔与导孔距离约200m,1990-1997年将钻到12000至14000m的目标深度.为钻干孔将设计一套全新的钻探设备.目前有250位科学家和技术人员为此项目进行工作.1985年在下萨克森地质调查所(NLL)内已组成一个项目管理组,以推动项目进行.
The Federal Republic of Germany Deep Hole Project (KTB) is a basic research project to examine the physical and chemical conditions and formation processes in the deep crust in order to gain a deeper understanding of the tectonic evolution dynamics within the continent. The purpose of scientific research includes the origin and The causes of the geophysical anomalies, as well as the physical and chemical conditions of the site, the effects of the fluid system on the crust, the geophysical formations and the evolution of the crust, and the installation of experimental facilities on the Earth’s Earths. Selected drilling sites in 1956, Near the town of Windischenbach in Wiessee, on the western wing of the Bohemia massif, on the right hand side of the junction of the Saxothuringian and Moldanubian regions of the Variscan range, where one can meet on the basis of the prospect of geophysical surveys Severely constructed crust. In 1987, a total of 3,000-5000 m deep access holes to be corroded were to be drilled and the drilling time lasted until mid 1988. This was followed by about one year of testing and Borehole Measurements By current planning, the distance between the ultra-deep borehole and the pilot borehole is approximately 200 m and a target depth of 12000 to 14000 m will be drilled from 1990 to 1997. A new drill Equipment. There are 250 scientists and technicians working for this project in 1985 in the Saxon Geological Survey (NLL) in the next project management have formed a group to promote the project.
