Adhesive wear of drill pipe is a wear phenomenon caused by the transfer of material from one surface to another or the shedding of material from the surface when the two surfaces of the friction pair slide relative to each other. Because the actual contact area between the two pair surfaces of the friction pair is very small, the contact point stress is very high, the friction pair pair surface is in this high temperature and high stress state, the rod surface cracks, so that the contact micro-peak produces adhesion, with the adhesion point in sliding is sheared. The bending of the drill pipe causes local friction with the rock formation, and the high stress at the local contact point constructs the condition of adhesive wear.
