THERMAL FIELD OF AN OIL BED IN A NONSTATIONARY PRESSURE FIELD A. R. Sabitov and R. F. Sharafutdinov UDC 532.546 We carried out a numerical investigation of the temperature field arising in an oil bed due to the Joule-Thomson effect and the heat of deaeration of the liquid in the nonstationary pressure field in displacement of oil by water. The formation of the temperature field depends substantially on the initial flooding of the bed and the approach of the front of the displacement of oil by water. The value of the water-oil ratio exerts an effect on the sign of the temperature anomaly at the outlet from the bed. JEPTER7492019993 JEPTER749203
