EFFECT OF DEPOSITION OF MECHANICAL IMPURITIES ON TEMPERATURE DISTRIBUTION OVER THE BORE OF PRODUCING WELL

The work is devoted to studying heat exchange processes of an ascending fl uid fl ow in a producing well during the deposition of mechanical impurities on its walls, for example, of asphalt–paraffi n deposits. A mathematical model and the results of numerical solutions of the formation of a temperature fi eld along the wellbore are considered. It is shown that due to a change in the heat transfer coeffi cient in the areas of deposition of mechanical impurities, a change in the temperature gradient in a nonstationary thermal fi eld is observed. The results obtained can be used in interpreting the data of thermodynamic studies of producing wells.
