摘要
悬链线轨道可大大减小钻进时的摩阻，所以在大位移定向井中具有显著的优越性。作者对自己过去提出的悬链线轨道设计方法作了改进。新方法的突出优点是，在所有设计计算公式中消除了双曲函数符号，使计算大大减化。文中除给出所有设计计算公式外，还给出了计算实例。
The catenary shape profile can greatly reduce the resistance of penetration.Therefore it has a prominent importance in long-displacement directional well. This paper is a improvement of the author's precedent design method of catenary shape profile. The advantages of the new method are deduction of the hyperbolic symbols in all design calculation equations and great simplifying calculations. Calculation examples were also presented.
