Influence of high-density drilling fluid weighted with conventional barite, micronized barite, hematite and manganese tetroxide on the wear behavior of N80 metal surface was investigated. The worn surface morphologies and roughness of the N80 metal was observed and tested respectively by scanning electron microscope and surface roughness meter tester. The wear mechanisms of different weighting materials were also discussed. It was found that the erosion rate of N80 steel worn by micronized barite is 57.8% of it worn by conventional barite, and the erosion rate of N80 steel worn by manganese tetroxide is 43.8% of it worn by hematite. The main wear mechanism of conventional barite, micronized barite, hematite and manganese tetroxide on the metal surface is abrasive wear, plowing, planning action and surface fatigue wear, under conditions of high density drilling fluid. Manganese tetroxide and micronized barite can significantly reduce the wear on the metal surface because of filling and adsorption on the concave and convex of the metal surface, especially the roughness of N80 steel surface worn by manganese tetroxide can be reduced to 50% of the hematite.
