[0010] Combine figure 1 Illustrative example is as follows: the present invention uses the biofuel automatic heater 1 to heat the heat carrier, and the double hollow sucker rod 2; the heat carrier enters the double hollow sucker rod 2 through the water inlet pipe 4 under the drive of the high-pressure circulating pump 3, and faces the well. Heavy oil circulating heating; the cold water circulating from the double hollow sucker rod 2 enters the liquid storage tank 6 through the return pipe 5, and the high-pressure circulating pump 3 pumps the water in the liquid storage tank 6 into the buffer tank 7 for buffering and gas-water separation, and The high-speed inflow biofuel automatic heater 1 is heated to form a heating system with a closed internal circulation of the heat carrier.
[0011] The heat carrier is driven by the high-pressure circulating pump 3 to overcome the frictional resistance of the pipe wall, flow to the inner hole channel 8 of the double hollow sucker rod 2 at hig...
