| Abstract: | The reservoir electric heating system is suitable for use in the recovery of heavy oil reservoir which is unsuitable to be exploited by means of steam injection. The heating system is comprised of power regulating device, power transmissiondevice, electrode, earthing device and record and monitoringapparatus. After an analysis of the operating principle of the heating system, some of the technological parameters are calculated, including the downhole electric resistance and temperature field produced in heating and the heat energy inside the oil bearing formation. The characteristics of the reservoir heating technology is analyzed, and the result shows electric resistance type reservoir heating system performs well. |
