Abstract
Description
technical field
[0001] The invention relates to the field of heating tubes, in particular to a three-phase super high-power heating tube. Background technique
[0002] At present, thermal oil recovery mainly uses some technological measures to increase the temperature of the oil layer. If the oil well is heated at about 300°C, it needs to be heated by a large-tonnage oil-fired boiler. Long, large heat loss, power consumption and oil consumption, environmental pollution, huge equipment, difficult handling, large maintenance, labor and time-consuming, extremely high cost, and poor economic benefits. It cannot be achieved by heating above 300°C and below 500°C.
[0003] The imported U.S. Unis fire flooding mining technology applies chemical combustion accelerants to ignite the flammable gas and liquid in the oil layer under the above conditions, and then injects a large amount of high-pressure air to support the combustion, so that the oil layer is burned and heated, and the c...
