对钻柱在井下的受力状况已进行过许多理论研究，但对钻柱在井下的实际工作状态的研究还不多。
The theoretical study for drilling string has been in progress for many years, but the real working state of drilling string still remains to be solved.
分析了井眼中钻柱在不同工作状态下的受力情况。
Analyses the drill string's force in different working conditions.
综合考虑钻柱惯性离心力和自重的影响，我们发现，在工作状态下，钻柱的临界压力会明显地小于静态时的临界力，这对实际的钻探工程来说具有十分重要的指导意义。
Considering the inertial eccentric force and the weight of the drill string, we find that the axis critical force will be obviously less than that under the static state, which wil...
