摘　　要：以QJ30-18型作业井架为例,应用大型有限元分析软件ANSYS分析了该井架的极限承载力。计算结果表明,只有采用几何和材料双重非线性的方法才能准确评估结构的极限承载力。In this paper,we take QJ30-18 downhole derricks as example, the ultimate load capacity of this type derricks have been studied by software ANSYS. Results show that the ultimate load capacity of der- ricks is dominated by structural stability. In order to determine the ultimate load capacity of the derricks both geometrical and material nonlinearities must be considered.

关 键 词：作业井架 非线性 极限承裁力
