  THEORY 
  We did it!

Upon the expiry of 100 years from the date of invention of roller bit we developed a new dynamic theory of interaction of roller bit with the bottom hole!
Dynamic theory of interaction of roller bit with the bottom hole while boring, which shows actual complicated interaction processes of the bit with bottom hole in mathematical language, allows calculating the cost-performance ratio of boring and manufacturing of roller bits with mathematical precision at the design stage.

The “trial and error” methods, and also methods of all possible statistical and probability modeling while development of more efficient rolling cutter drilling tool have passed with no hope of return.

It is time for precise mathematical calculation of roller bits, designed ...

  Features of operation of a roller bit with rock superbreaking down

Operation of a roller bit with superbreaking down (overbreak) or the locked up spalling of rock at well boring, is grounded on scientific established fact, that rocks destroyed by a roller bit in the majority have unique properties: very strong resistance to a compression failure and, rather, easy resistance to breaking down - at curving and extension.


   
   To use while drilling unique properties of rocks at their breaking down mechanically, it is necessary to count with mathematical fidelity, both arrangement of a teeth for surfaces of milling cutters, and geometrical arguments of milling cutters and ...
