Abstract

Rotary liner hanger bearing will be wear sharply and decreased its service life if the sealing structure is not able to prevent the drilling fluid to enter into the bearing. A two-dimensional finite element model of the self-designed non-standard rubber sealing ring was carried out on the software of ABAQUS. The rules of deformation and stress for the sealing ring with different value of initial interference, working pressure and the deep-well temperature were studied. The result shows that the maximum contact stress increases with the increase of value of initial interference and the maximum contact stress is always bigger than the value of work pressure. The effect of deep-well high temperature on sealing performance is not obvious compared with normal temperature. The result of this study is able to be the basis of modifying the structure and improving the performance of sealing ring.
