摘要
根据小眼井钻具细、刚度低等特点 ,充分考虑钻具与井壁的接触碰撞 ,建立了小井眼直井钻柱力学模型和理论分析方法 ,由此分别建立了小井眼直井钻具性能评估准则和钻柱动强度条件。实践证明 ,小井眼直井钻具性能评估准则和钻柱动强度条件是正确的 ,有效地满足了钻井工程需要。
Based on the drilling assembly and low rigidity in slim hole and fully considered the contact collision of drilling tool with well bore, the drilling string mechanical model and theoretical analysis method are founded. Valuable standards on drilling tool feature and drilling string dynamical strength in small vertical well are also derived. Practical applications show that the standard and dynamic strength conditions are correct and meet the field requirements effectively.
