卡瓦内悬挂管柱承载能力的再分析

ANALYSIS ON THE LOAD BEARING CAPACITY OF TUBES INSIDE SLIPS

以往在国内外对卡瓦内悬挂管柱承载能力的研究中，出现了多种研究模型，但其求解方法均不同程度地存在一些问题和不足。鉴于求解方法对油井特别是深井和超深井的套管柱设计十分重要，对原有文献中存在的问题进行了剖析，并按原有模型进行了正确的计算。

Analysis on the load bearing capacity of tubes inside slips is very important for the design of well casing string, especially for that of deep well and super deep well. There are many different models for calculating the load bearing capacity of tubes inside slips. Those models have some shortcomings in solving process. This paper points out the mistakes of some references in analyses on the load bearing capacity of tubes inside slips, and gives the correct calculating results.
