Abstract
In this article are presented and simulated series of dates regading the geothermal gradient distribution in the Moesic Platform, using the temperature measurements done in oil exploration and production wells. Knowing the thermal conductivity and the geothermal gradient of rocks it is possible to estimate the heat flow, one of the main parameters for the thermal state of geological formation characterization. They are presented the main problems of geothermal conductivity of rocks measurements in the laboratory conditions.
