Outline of Final Research Achievements

The Stick-Slip and large bending deformation due to Magnus effect are troublesome problems which happens in scientific drilling. In order to clarify the mechanism of Stick-Slip and large deformation, it is necessary to develop a reliable numerical model to estimate drill pipe motion for various drilling conditions. Stick-Slip was estimated using a numerical procedure to solve NDDE (Neutral Delay Differential Equation) and large bendig deformation due to Magnus effect was estimated using ANCF (Absolute Nodal Coordinate Foumulation). The boundary condition at the drill bit part for NDDE equation is estimated from measured top drive torque and calculated Stic-Slip motion was agreed well with measured data of actual drilling. On the other hand, the hydrodynamic forces on drill pipe for calculating bending deformation of the drill pipe are estimated from model experiments and CFD. The estimated bending deformation of the actual drill pipe varied depending on the ocean current conditions.

Academic Significance and Societal Importance of the Research Achievements

長大管の捩じり振動の問題は海底掘削のみならず、陸上での掘削においても問題となる現象である。この問題の数値解法における難点は掘削面での境界条件が不定となるため、従来法での求解がでいないことにある。本研究では計測可能な上端回転トルク、船体動揺データなどから合理的に掘削面での境界条件を定めて数値解を求め、計測結果と妥当な一致をみている。NDDEを解くこの手法では初期履歴条件を設定する必要があるが、安定的な数値解を得るための初期履歴の与え方についても考察を行っている。また、マグナス効果による大規模曲げ変形についても実機スケールで推定可能な手法を示しており、海底科学掘削の効率的運用に資する。
