本文对目前尚无定论的立井井筒深度的划分，提出了分浅井、中深井、深井、超深井和特深井的五级划分界限；对深立井刚性井筒装备从材料、截面形式、层格结构、设计依据、计算模型、计算方法等方面进行了详细的理论分析和展望评述。 In this paper, there is still no conclusion about the division of vertical wellbore depth, and the five levels of subdivision shallow shaft, medium deep shaft, deep shaft, ultra-deep well and extra-deep well are proposed. The rigid shaft well equipment of deep shaft is composed of material, cross-section, Design basis, calculation model, calculation methods and other aspects of a detailed theoretical analysis and outlook comments.
