弹簧理论在井下作业管柱力学分析中的应用

Application of Spring Theory to Mechanics Analysis of Downhole Pipe String

井下作业中有许多管柱受力发生螺旋状弯曲,形状像弹簧,用弹簧理论对井下作业管柱进行力学分析,得出材料破坏的强度条件,从而推出适合现场应用的实际条件,用以指导现场井下作业。

During downhole operation the pipe string is often spirally bent and becomes curved like a spring.Analyzing the string with spring theory gives the strength of the material when it is damaged and so gives the conditions under which the string is applicable and gives a guide to downhole operation in field.
