| 摘 要： | 中原油田在卫２８１井定向井段首次下入双层组合套管，以预防盐层套管的损坏。本文以弹性力学有关理论为指导，对盐层段双层组合套管强度进行了理论推导计算。实践表明，双层组合套管在盐层段和其它特殊层段的应用，对预防套管损坏是切实可行的。

| Abstract: | Dual combined casing has been put in the section of oriented well to prevent the casing from collapsing in the well Wei 281 of Zhongyuan Oilfield for the first time. This paper derivates and computates the dual combined casing strength in salt rock with the theory of elastic mechanics. It has been proved that dual com bined casing used in salt rock and other strata are reliable for preventing the casing from collapsing. |
