摘要

摘要: 为完善套管非均匀挤毁失效机理的理论研究，开展了C110套管的非均匀挤毁实验，通过精密的压力试验机给套管施加非均匀载荷，进而得到套管不同载荷下的径向位移。采用在套管外壁粘贴电阻应变片的方式来测量套管在挤毁过程中的应变，进而得到了套管的屈服载荷、失稳载荷以及套管在非均匀载荷下的变形规律和失效机理。

Abstract: In order to perfect the failure mechanism of casing under non-uniform loading, the collapsing experiments were performed for C110 casing under non-uniform loading. The non-uniform loading on C110 casing was applied with the sophisticated pressure testing machine and the radial displacements of casings have been obtained under different loading. Simultaneously, the strain of C110 casing was measured in the process of collapsing testing by gluing strain-gauge on the outer surface of C110 casing. Some experimental conclusions such as the yield load casing, instability load of casing, deformation law and failure mechanism have been obtained under non-uniform loading.
