Аннотация: A comprehensive technique for calculating the coupled heat transfer of the well and the surrounding rock, taking into account phase transitions (thawing and freezing) and drilling fluid circulation, as well as its thermophysical and rheological characteristics, has been developed. Detailed testing of the developed technique for calculating the hydrodynamics and conjugated heat transfer of the well and the surrounding rock was carried out. The calculated time dependence of the permafrost thawing radius is consistent with the well-known analytical solution, as well as the experimentally observed value of the thawing radius.
