摘要
本文以铅直井眼中的线一弹性力学井壁稳定性分析为基础,对井壁力学稳定性原理及影响因素进行了全面而深入的分析,分析结果表明,现有的井壁力学稳定性模型及强度判别准则具有较大局限性,寻找更为有效的解决办法势在必行。
Basing on the analyses of the linear-elastic wellface mechanical stability in a vertical well, this paper makes a comprehensive and profound analysis of the principle of wellface mechanical stability and its influence factors. The results show that the persent wellface mechanical stability models and strength criteria are rather limitative. Therefore it is imperative to seek for more effective solutions.
