Based on the theory and method of casing string design, starting with the analysis of the triaxial strength design theory of casing string, the stress of casing string is analyzed comprehensively to establish the mathematical model of casing strength calculation and payload calculation , Gives the method and procedure of using computer to realize casing string design, and compiles corresponding casing string strength design software. Combined with the examples of on-site design, through the calculation and analysis, it shows that using three-axis strength theory to design casing string strength With a comprehensive analysis, high accuracy.
