Abstract: Superdeep drilling is currently one of the most complex technical tasks of our time, requiring large costs, new engineering research and a large scientific and technical base. Not every country benefit from such a costly innovation, but nevertheless, the prospects that open up to mankind with the development of this direction are quite great. Scientific discoveries made during the drilling of superdeep wells became the basis for new assumptions about the structure of the Earth's crust and forced to reconsider the theories, on which the modern geology was based. For example, drilling revealed water where it was previously thought to be impossible. This suggests that hydrocarbons may also be at greater depths, due to their flow down overlying porous reservoirs. Also, drilling has found metals in pure form and in concentrations not previously thought possible, as well as the fact that they can be at such depths.
Scientific superdeep drilling is necessary for the further development of geology, because the data obtained from drilling are the most reliable and allow us to study the geological structure of regions with great accuracy. The cores obtained can serve as physical evidence for geology's theories about the origin of the earth, along with the study of meteorite remains.
This article considers some aspects of the use of modern equipment for superdeep drilling. It shows consideration of the possibility of using the newest Russian drilling rig, which will allow a more substantial approach to the design of wells with a depth of more than 7 km. Some technical characteristics and description of the main units of the drilling rig DR 15000/900 DER are given.
