1) washover-string
套铣筒
1.
Stress distribution and mechanics analytical methods of washover-string are different from the common drill string (such as drill collar) because that the structure features of two kinds of strings are so different.
由于修井专用的套铣筒与常规钻井施工所用钻柱在结构上存在很大差异,套铣筒内应力分布与常规钻柱(钻铤)内的应力分布不同,力学分析的方法也不同;本文在对套铣筒进行力学分析以及摩阻力计算时,充分考虑了其结构特点:直径大、壁薄、环空间隙小。
2) closed-window tapered milling barrel
变径套铣筒
3) Composite washover and fishing cylinder
复合套铣打捞筒
4) mill

补充资料：复合型内筒
分子式：
CAS号：
性质：综合冷管型、冷激型内筒结构的优点组合而成的一种氨合成塔内筒结构。其优点是操作稳定、气流分布均匀，塔内阻力小、气体空速大，氨净值高等。缺点是结构复杂，制造、安装、维修均不方便。
