Thermal Control Devices for Oil Wells


A thermal control device is developed for use in oil wells to decrease asphalt–resin–paraffin deposits. The influence of the heat-flux density in the heating elements on the device’s internal wall temperature is studied. The dependence of the internal wall temperature on the flow rate of working fluid and the heat-flux density in the heating elements is determined. The optimal distance between the heating elements is established as a function of the flow rate of working fluid.
