| 摘 要： | 在水平井管柱屈曲临界力和屈曲后管柱与井壁的接触力这两方面研究中存在着不同的结论。本文对理论和试验的不同结论进行了分析，指出产生这种不同结论的原因，一是推导方法不同，二是试验条件不规范。认为有关这方面的研究有必要在理论、试验和现场三者结合下，建立科学计算方法，以便得到更正确的结论。

| Abstract: | There are diverse conclusions in the study of the two aspects - critical forceof buckle of drill string in horizontal well and the contact force of buckled pipe string onborehole wall. This paper analyzed the diverse theoretical and experimental conclusions andpointed out the reasons of occurrence of the diverse conclusions - the first is about differentdeduction methods and the second is unspecified test conditions. In order to reach correctconclusions, it is necessary to set up a scientific calculation method combining theoretical research, pilot tests and rig-site experiences. |
