摘要
管柱弯曲临界力是判断井内管柱是否弯曲的重要依据 ,也是解决封隔器管柱受力分析中十分重要但又令人费解的“虚力”问题的关键。
Bending critical force of test string is the important gist to estimate whether the string in well is dended or not, is the key to solve the question of fictive force that is very important and bewildering in analytical system of packer string endured force, too. Bending critical force of packer string existing fluid in well is deduced and analysed in the paper.
