INFLUENCE OF RELATED FACTORS ON WELLHEAD TEMPERATURE IN MECHANICAL RECOVERY WELL

The physical property and rheological behavior parameters of the flow in thewellbore are sensible functions of temperature. It is of fundamentalimportance to calculate the temperature field for the optimization designof an oil/gas production scheme. Based on the thermal conduction theory, amathematical model is formulated for the temperature calculation of the wellborefor mechanical recovery wells. The influences of such factors as the wellyield, water content, well depth, pipe radius, ambient temperature andgeothermal gradient, on the wellhead temperature are investigated.
