为了确保石油开采的顺利、安全进行，针对套管柱三轴应力的受力特征，应用套管柱三轴应力校核的最新理论模型，给出了应用计算机实现套管柱设计的方法和步骤，并编制出套管柱三轴应力校核软件。具体实例测试表明，应用最新套管柱三轴应力校核理论设计的软件能够较好地满足工程需要。

In order to ensure the successful and safe implementation of oil production, in view of the force characteristics of casing triaxial stress, the methods and steps of computerized casing design are given through the application of latest theoretical model of casing triaxial stress checking in this paper. And checking software of casing triaxial stress has been developed. Concrete examples and testing results show that the software, which is designed in terms of the latest casing triaxial stress checking theory, can satisfy the needs of project.
