Abstract

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.

Key words: Stabilizer, Deep drilling, Rigidity, Strength, Finite element method
