Using a comprehensive approach, a systematic analysis of studies in the field of heat transfer and temperature distribution along the length of oil production wells along the height of the production casing (PC) and the tubing is given. In these studies, a significant number of analytical solutions were obtained as a result of analytical research on the subject. It is shown that as the temperature decreases along the height of the production casing (PC) and the lifting tubing, the probability of asphaltene-resin-paraffin deposits (ARPD) increases, leading to complications in the oil production well (OBW). In this paper, we propose new mathematical models for determining the temperature distribution (TD) along the height of PC and the lifting tubing, taking into account the geometric gradient and temperature gradient in the liquid and gas layer of PC. A mathematical model and geometrical interpretation of heat transfer processes in the tubing is also proposed. It is shown that TD at the height of the tubing differs significantly from TD along the height of PC. The temperature log (temperature curve) along the PC borehole and the tubing is given.
