육상시추 시스템용 방향제어 추진체의 수치해석 기법 분석

The most important part of the directional drilling is the transition from vertical drilling to horizontal drilling. This is possible due to continuous development of various control systems and stability of drilling equipment. Directional drilling equipment performs drilling, including mud system. In this study, structural stability is analyzed prior to the development of directional drilling. this study intend to analyze the numerical analysis cases that can be evaluated to establish the scope of application for future developments.
