摘要
分析尾管在下入过程中,往往会遇到管串与井壁摩阻偏高、下放过程中遇阻无法通过的情况,而能够下划眼的尾管,即可有效解决下钻困难的问题。阐述可旋转尾管是顺利下到位、预防井下复杂情况发生的坚实保障。
This paper analyzes that in the process of running the liner,the friction between the string and the well wall is often high,and it is difficult to pass when the friction is encountered in the process of running the liner.The problem of difficult running in can be effectively solved by running the liner with reaming.It expounds that the rotatable liner is a solid guarantee for smoothly running in place and preventing the occurrence of complex underground situations.
