FIELD: oil and gas industry.SUBSTANCE: invention relates to support-centering elements of a drill string can be used in drilling deep wells. Vibration damper-calibrator includes housing with central hole for the flushing liquid supply well shaft two connecting threads its installation into string, divided by external channels separate working sectors, each which is equipped pushing floating spring-loaded dampers-elements transverse oscillations extending above casing surface, outer surface...
Currently, roller bits are widely used in rock drilling, which devices with rotating rollers armed teeth. There various approaches assessing the effectiveness of destruction by a drilling tool, can be conditionally divided into structural and technological ones. In addition, all efficiency factors bit related to correspondence its characteristics process properties it destroys. The article analyzes operating conditions during rocks hardness. On example operation two-screw drill bit, power...
