The Structure Improvement Design of Turbodrill Diversion Liner

Abstract:

In order to improve the work life and reliability of turbodrill diversion liner, the parametric finite element model for turbodrill diversion liner is established by using finite element analysis software, and the result of finite element analysis is shown that the maximum equivalent stress is bigger and the work safety coefficient is low. On the basis of the result of finite element analysis and the characteristics of diversion liner, the improvement scheme is put forward and the finite element analysis is carried out. The analysis result shows that the fillet radius of diversion hole drilling fluid inlet has an importance impact on the maximum equivalent stress. When the fillet radius is 9 millimeter, the maximum equivalent stress is least, the maximum equivalent stress is reduced by 34.82% compared with the original structure, and the safety coefficient reached 1.772, and the results meet the design requirement.
