Abstract
The sand of drilling flow that enters into rotary liner hanger bearing will wear the bearing, which will reduce its service life seriously. Applying the fluid software, this paper simulated the wear characteristic of fluid domain inside the bearing. Based on the Finnie wear model, this paper analyzed the erosion rate of bearing with different particle size and density of drilling fluid. The results show that, when the density is constant, the erosion rate decrease with the increase of particle size. On condition that the particle size is constant, when the density of drilling fluid is low, the erosion rate increases with the increase of the density until the density reaches a certain large value, then the erosion rate decreases firstly and increases later with the increase of the density. The erosion rate is the lowest when the particle size is 0.07mm and density is 1960kg/m3 from the simulation result.
