The new design scheme of drilling rock cutting tools, working in rotation mode pairs

The article describes the dynamics of drill bits, drilling modes, distribution resistance forces when with bits. theory a well arbitrary shape, possible shapes contacting figures at bottom hole and type bit operating in rotation pair mode are considered. This has properties double center rotation, which results attrition drilling. At same time, during drilling, load on will be located throughout working part, it is also theoretically shown that specific volumetric contact work cutting parts same, leads to wear bit. It discusses issues improving flushing blowing wells rotary steam
