Abstract:

Analysis, study and assessment of the dynamic state of drilling bits through analytical method of investigating interactions and total loads on drilling bits in specific cases have been carried out based on real data after the construction of directional wells using rotary drilling technique at Bach Ho and Rong oilfields of Vietsovpetro. In this paper, the authors would like to present a methodology and outcomes of study on dynamic state of bit, and as a consequence, to optimize the steering during the process of contructing a directional horizontal well.
