摘　　要：套管在弯曲井眼里的可下入计算,是在下套管作业前判断在弯曲井眼能否顺利下入套管的重要计算依据。采用解析法和有限元法对非API规格套管在弯曲井眼里的可下入性进行分析计算。结果表明:解析法和有限元法计算的结果基本一致;解析计算公式能够满足现场运用,为非API规格套管下入提供理论支持。Calculation of accessibility of casing going through well bending section is an important way to judge whether a casing is capable of going through a well bending section before the actual casing going-down operation. Using the analytical method and the finite element method (FEM), the accessibility of non-API casing going through well bending section is analyzed and calculated. It is shown that the results of the analytical method and that of the FEM are basically the same. The analytical calculating formula can meet the requirements of the field and provide theoretical support for the going-down operation of non-API casings.
