| 摘 要： | 采用有限元法对钻井全尺寸综合模拟试验装置中并架所作的结构静动力分析表明，该结构设计满足强度和刚度要求。井架结构第一阶固有频率在正常工作位置时为１５．４４Ｈｚ，在最低工作位置时为１６．８８Ｈｚ。当使用三牙轮钻头的工作转速变化范围为３５～３００ｒ／ｍｉｎ时，井架不会发生共振。

| Abstract: | A static and dynamic analysis of the derrick on the full-scale comprehensive drilling test unit is made by the finite element method, and the result shows that the design features of the derrick meet the requirements of strength and rigidity. The first-order inherent frequency of the derrick in the regular working position is 15. 44Hz and that in the lowest working position is 16. 88Hz. No resonance will happen while the rotating speed of the three-cone bit ranges from 35 to 300rpm. |
