CU PRIVIRE LA MODELAREA ȘI SIMULAREA VIBRAȚIILOR TORSIONALE ALE GARNITURII DE FORAJ ROTATIV

Octavian Dinu

Abstract:

The paper presented an oil drilling mechanical vibration systems modelling. This paper presents simple but effective modeling and simulation method for a drillstring system, by considering the friction of the bit on the bottom hole assembly (BHA) in oil wells. In the drilling processes there are different types of vibrations, one of them and for which we are interested in this work is torsional oscillations. These oscillations are induced by nonlinear frictional torques between the drill bit at the rock surface.

Keywords:
modeling, simuling, torsional oscillations, oil drilling processes, simulink.
