Abstract: This article presents the foundation of the temperature distribution mathematical model when the thermoelectric devices are installed on external walls of oil and gas wells, the operation of which is based on thermoelectric Peltier effect The model practical use allows to estimate the current temperature of permafrost depending on design parameters of the well, downhole thermoelectric devices, and the temperature of frozen rocks phase transformation, and also allows you to build graphs of these dependencies in real ranges. Downhole thermoelectric device is designed to reduce the thermal impact of oil and gas wells in permafrost rocks during their construction and operation in the climatic conditions of the Arctic territories.

Key words: permafrost frozen rock well mathematical model downhole thermoelectric device thermoelectric module Peltier effect
