| 摘 要： | 可变径稳定器与整体式稳定器(固定径)相比，它更能有效地保证井身质量，是目前较先进的钻井工其之一，目前我国还没有同类产品生产。本文所分析的可变径稳定器，是我院与四川石油管理局某机械厂联合研制的深井可变径稳定器，目前正在试制之中.本文利用有限元法，详如分析了该型号稳定器的强度和刚度，为设计提供了可靠的理论依据.

| Abstract: | Compared with an integral stabilizer with fixed diameter，a stabilizer with variable diameter can effectively ensure the quality of a well body，and is one of the most advanced drilling tools，The stabilizer with variable diameter discussed in this paper is a deep well stabilizer with variable diameter，which has been developing jointly by our institute and a mechanical factory under Sichuan Petroleum Administration Bureau，and which is now being trial—produced. So far no other similar products have been produced in China. In this paper the finite element method is applied to the detailed analysis of its strength and stiffness，and a reliable theoretical basis is provided for its design. |
