FIELD: oil and gas industry.
SUBSTANCE: stopped well is chosen; its flushing is performed, and with that, temperature at the circulation system outlet is recorded. With that, pumping of hot liquid (heat carrier) is performed through annular space, with that, at its inlet the liquid temperature varies as per a periodic law and is recorded, and heat conductivity coefficient λ"п" and coefficients of heat transfer through tubing strings k1 and casing string k2 are calculated as per mathematical formulas.
EFFECT: improving measurement accuracy of an average integral value of heat conductivity of mine rocks as to a well log and determining coefficients of heat transfer through the tubing strings and through the casing string, length of the circulation system of the well.
