摘要
本文把内含钻井液的旋转钻柱简化为一充液柔性转动系统，对钻柱内钻井液对钻柱的受力状况及涡动形式的影响进行了详细的力学分析，推导出了实现钻柱规则涡动的动力学条件。
The revolving drilling string of inside contining drilling fluid is simplified as a flexible rotary system in this paper.The influence of drilling fluid in drilling string on forced situation of the drilling string and eddy form is mechanically analysed in detail. and the dynamic conditions making the drilling string regular eddy are deduced out.
