FIELD: physics.
SUBSTANCE: invention is related to the field of thermalphysic measurements. Substance of invention consists in the fact that rock sample from well core with smoothly polished end surface and sufficiently large length is exposed to local heating with permanent power source in the form of circle and values of its average integral excessive temperature that change in time are registered. As soon as permanent rate of temperature change is achieved depending on time in degree "plus 0.5", thermalphysic properties of sample are determined.
EFFECT: exclusion of measurement errors, which are provided by distortion of sample temperature field due to finiteness of its diameter.
