摘要
通过对套管强度设计最新标准SY／T5322-2000的几个相关问题的分析,着重讨论了标准中三轴抗 拉强度计算公式和套管有效外挤载荷计算方法,改正了标准中的几个计算公式;同时还对新旧标准套管内 压载荷计算方法进行了对比分析。
This paper analyzes several relevant problems on the latest SY/T5322 - 2000 standards of casing strength design, discusses emphatically the formulas of triaxial tensile strength and computational method of effective external pressing load of casing in the new standards, and corrects several formulas in the new standards. It also compares the calculation methods of internal pressure load in the new standards with that in the old standards.
