Common method of accounting for the deterioration of the filtration properties of the reservoir is the in-troduction of a dimensionless coefficient - skin factor. Traditionally, in order to determine the value of skin factor hydrodynamic research methods (well test) at non-stationary modes are applied (pressure recovery curve, level recovery curve) are used. In recent years, along with the pressure in well logging, bottom hole temperature dynamics is also recorded, that allows to use this data for obtaining the additional information about the reservoir and is a slower process, also about near wellbore zone. In this paper the possibility of de-termining the radius of the zone of permeability deterioration in the near wellbore zone from the non-stationary temperature measurements in well is studied; and also the sensitivity of the inverse problem solution to variation of simulation parameters.
