FIELD: oil and gas production industry. SUBSTANCE: this is used at thermal treatment of well and well surrounding zone. Method implies creation of heat flow and determination of temperature at least at one point located in vertical at distance above and/or lower from point of creating heat flow according to melting of meltable materials of different melting temperature located with possibility for self-removing at melting. Part of meltable material is located in contact with medium and its temperature is measured, and other part is beyond contact and this part is mechanically fixed. Temperature at point of creating heat flow corresponds to specifications of material being burnt out. EFFECT: high efficiency. 2 dwg
