The processes of metal corrosion in water-oil mixtures depending on the level of water mineralization, reaction of the environment, and ratio between the volumes of oil and aqueous solutions at temperatures of 20 oC and 80 oC were studied. It is shown that the corrosiveness of the medium against metals becomes higher with increasing level of water mineralization and acidic content with decreasing pH of the medium and increasing temperature. The corrosion rate of metals is significantly reduced in the presence of oil. Increase in the oil content in water-oil mixtures has little effect on the corrosion rate of metals. Increase in the hardness of water in the presence of acetic acid does not reduce the corrosion rate of metals and, in some cases, there is an increase in the corrosion activity of water with increasing hardness.
