Turbodrills DEVICE TO REDUCE longitudinal vibrations SYSTEM: drillstring BODY turbodrills-TREE turbodrills, chisels

摘要

The proposal aims at solving the problem to improve the processing and turbodrill bits due to decrease of the intensity fluctuations of the interconnected system, the drill string, casing turbodrill - shaft turbodrill bit during drilling. The problem is solved by creating in the lower part of the last section of the turbodrill throttling device, with provision for the passage of fluid flow therethrough in a sinusoidal mode vibrational phenomena system are reflected in the chamber with providing oscillation differing amplitude and frequency of the bit oscillations Harmonic sinusoidal oscillation superimposed on the system and translates them thereby to equalize
