Under thermal flooding of strata, the temperature conditions in the reservoirs are formed mainly in the process of heat exchange between the injected fluid and reservoir with the surrounding rocks. Heat transfer in the strata is composed of conduction through the solid porous skeleton, conduction and convection through the pores and other factors. Particularly acute appears the need to analyze temperature fields and recovery of reservoirs saturated with paraffin. Methodological issues that arise when analyzing temperature fields, pressure and oil saturation should be carefully handled, with special concern to multilayer formations. It is necessary to consider the heat exchange between the reservoir and the surrounding rocks. The article offers the technique of calculating temperature fields and the oil saturation with oil displacement by water in multilayer formations taking into account heat transfer through the roof and sole.
