Abstract
West Germany has started a project of the world deepest boring of 14km depth which requires more than 10 years and as much as 40 billion yen. This is a national project of scientific research called Continental Deep Boring Project(abbreviated as KTB). This project was proposed by the West German Research Association about 10 years ago, and pre-investigation, technical investigation and selection of proper field were started in 1981. The project was approved by the Federal Research Technology Ministry in 1985 and was started with the overall budget(upper limit) of 450 million Deutchemarks. At present, a 5,000m deep well for the investigation of the shallow part is being drilled, and mud analysis and core analysis are being carried out. Super deep drilling is comprehensive system engineering that includes the robotizing of lifts, the development of drill pipe material which is strong and light enough not to be torn by its own weight, the improvement of the turbo drill bit, and the development of heat resisting and pressure-tight semiconductor for in-the-bore-measuring instruments. In West Germany, the official, civil and academic circles participate in this project. 18 figs., 2 tabs.
