不规则井筒内力学分析与施工参数优化

Mechanics analysis and construction parameter optimization in irregular wellbore

不规则井筒越来越多,水平井的井斜、方位角变化,都会增加井下作业施工难度,影响钻具起下负荷、钻磨铣施工参数。通过简单研究钻具在不规则井筒内的受力,解决施工中的疑问,避免钻具在井筒内因吨位不准确而影响施工效果,甚至造成井下工程复杂事故。

More and more irregular wellbore,the deviation and azimuth of horizontal wells change.It will increase the difficulty of downhole operation and affect the drilling tool load,drilling,grinding and milling construction parameters.By simply studying the force exerted on drilling tools in irregular wellbore,the problems in construction are solved.To avoid the inaccurate tonnage of drilling tools in the wellbore,which will affect the construction effect,and even cause complex accidents in underground engineering.
