摘要： 本文对套管三轴应力设计原理进行了讨论,推导了三轴应力强度公式,对套管柱的受力情况进行了全面分析;同时提出了以等安全系数法为基础的改进等安全系数法,该方法在外载考虑上比等安全系数法更全面合理,设计步骤有所改进。以提出的方法为基础,结合现场实际,在微机上开发了相应的商品化软件,在现场获得了广泛使用。

Abstract: This paper discusses the principle of triaxial stress design of casing strings, deduces the strength formula of triaxial stress, and analyzes the overall external loads applied on the casing string.The modified equal safety coefficient method is put forward on the basis of equal scatter coeffi-cient method. The new method is more reasonable than equal safety coefficient method when dealing with external loads, and it improves the design procedure. Based on the proposed method and in combination with the practice of oilfields, the software for strength design of casing string is developed and has been widely used in oilfields.
Key words: Casing string design, Casing strength, 3D model, Casing pressure, Casingstress, Computer program
