Abstract: The physical property and rheological behavior parameters of the flow in the wellbore are sensible functions of temperature. It is of fundamental importance to calculate the temperature field for the optimization design of an oil/gas production scheme. Based on the thermal conduction theory, a mathematical model is formulated for the temperature calculation of the wellbore for mechanical recovery wells. The influences of such factors as the well yield, water content, well depth, pipe radius, ambient temperature and geothermal gradient, on the wellhead temperature are investigated.
