This article focuses on the effect of oil temperature on paraffin waxing of oil field equipment. Analysis of paraffin-waxing of oil field equipment at West Siberian oil fields has shown that the number of wells troubled by wax deposits has been going up every year. Wax deposition causes fall in oil recovery and entails additional cost for deposit removing. To prevent resin-wax deposits, it is essential to study their formation process in real oils. Until now, this process has been poorly studied because of wide diversity of properties and compositions of oils. In view of development of new oil fields characterized by heightened bed temperature and substantially increased wax content as well as of oil fields located in regions having permafrost soils, there is a pressing need for investigating the composition and properties of deposits formed in a wide range of temperature gradients. In the experiments, the authors used in-situ oils with diverse component compositions, which were collected from four clusters of wells located in various corrosion-active areas of the Samotlor field.
