摘要
按水力外压考虑的石油套管抗挤能力计算方法，不符合实际情况，实际上套管承受着复杂载荷。本文对套管受非均匀载荷的变形问题进行了探讨，提出了水泥约束套管抗挤能力的计算方法，给出了计算套管变形的力学模型。实例计算表明。这种计算方法符合实际情况。
The calculation method of oil casing collapse is not correct whenconsidering hydraulic pressure only. The oil casing in oil well is subject to complicatedloads.Non-uniform loads on the oil casing is studied in this paper.A calculation method forcollapse of oil casing is proposed. The mechanical model for the strain casing are given. Thestudy indicates that the result obtain ed by this method is in good agreement with actualsituation.
