ANALYTICAL-STATISTICS METHOD FOR THE CALCULATION OF THE HEAT TRANSFER IN THE WELL
Abstract
EOR thermal processes involve both introducing of warm fluids in oil reservoirs through injection wells and also extraction of warm/cool fluids through production wells. A model that describes the process for heat transfer from the fluids flowing through the well at its contiguous environment, and the calculation of the temperature along the well can be used in various applications of heat transfer aspects, especially when the bottomhole equipment of the well doesnпїЅt allow measurement. This paper presents a model that describes the process of the heat transfer from the fluids flowing through the well at the crossed layers. The model is based on mass and energy balance in the assumed conditions. The proposed model can be applied to the beam pumping wells, where the existing equipment in the well does not allow introducing of temperature measurement tools along the well. This temperature profile has various applications, such as: determining the reservoir temperature in the area around the wellbore for elaborating maps of temperature distribution in order to monitor the efficiency of the thermal process, the determination of failures of the bottomhole equipment and so on.
