Compared with the medium frequency electric heating oil production device, this utility model has the advantages of energy saving, environmental protection, safety and stability. Compared with the single well thermal fluid intelligent heating device, this utility model has the advantage of saving the investment cost of ground equipment. When used in oil wells with sufficient associated natural gas, compared with the medium frequency electric heating oil production device, this utility model has the advantage of saving the investment cost of ground equipment. The high-frequency electric heating oil production device can save about 80% of the operating costs. Through the use of multi-well centralized control mode, this device can save the investment amount of ground equipment for platform wells, and reduce the average cost of a single well by about 1 / 3. The booster pumps are evenly distributed on the right side of the liquid storage tank, and the distribution box is set inside the operation room, which is more convenient for the staff to operate and prevent the situation that the distribution box is not designed inside the operation room during use and cannot be operated. The voltage regulator is rotatably connected to the burner, and the gas pipeline is slidably connected to the voltage regulator, which is more convenient for the voltage regulator to rotate and avoids the voltage regulator being stuck by the burner during use, which makes it impossible for the voltage regulator to continue to rotate. The output end of the thermal insulation inner tube is arranged on the right side of the hollow sucker rod cross, which is more convenient for the thermal insulation inner tube to output and prevents the situation that the output end of the thermal insulation inner tube is not designed and cannot be used during use; the wellhead is arranged in the middle of the oil well body, and the sucker rod buckle is arranged in the middle of the oil well body, which is more convenient for fixing the sucker rod buckle and avoids the situation that the sucker rod buckle is stuck by the oil well body and the sucker rod buckle cannot be used; the oil pump is slidably connected to the oil well body, and the oil pump is arranged in the middle of the inside of the oil well body, which is more convenient for the oil pump to slide and prevents the situation that the oil pump cannot be taken out for cleaning due to the oil well body being stuck during use.
[0020] Working principle: The heater 4 of the device is installed on a working platform in a non-flammable and explosive place 13, 15m away from the wellhead and more than 0.5m above the ground. The operation room 8 is integrated with an intelligent control distribution box 1, a liquid storage tank 2, multiple booster pumps 3, a heater 4, a burner 5, a pressure regulator 6, and a gas pipeline 7. The inlet of all booster pumps 3 is connected to the outlet pipeline of the liquid storage tank 2, and the outlet is connected to the inlet of the heater 4; the outlet of the heater 4 is divided into multiple routes and connected to the interface of the hollow sucker rod 4-way 10 of the oil well body 9 through the pipeline, and the circulating fluid returned from the annulus of the hollow sucker rod A12 and the insulating inner tube 11 is connected to the main return pipeline through the pipeline and returned to the liquid storage tank 2. The operation of the booster pump 3 and the burner 5 are all uniformly coordinated and controlled by the intelligent distribution box 1 to ensure the safe, reliable and stable operation of the utility model device. The hollow sucker rod A12 passes through the wellhead 13 and goes down into the oil pipe 14, and is connected to the oil pump 16 through the sucker rod buckle 15; the upper end of the hollow sucker rod A12 is connected to the hollow sucker rod 4-way 10, and the middle insulation inner tube 11 is installed in the hollow sucker rod to form an internal circulation passage. An external passage is formed between the insulation inner tube and the hollow sucker rod. The high-temperature liquid enters from the insulation inner tube 11, returns from the annular outer passage between the hollow sucker rod, and flows back to the liquid storage tank 2 through the pipeline. In the process of high-temperature liquid returning from the annular space, the heat is transferred to the oil pipe 14 through the hollow sucker rod. There are multiple circulating media in the device, which can be selected according to actual needs. In general, the circulating fluids mainly include softened water, antifreeze, thermal oil, etc. Softened water has the lowest cost and carries the most heat, so it is the first choice for this device. Thermal oil has the highest cost and carries less heat than water, so it is suitable for use in ultra-high temperature environments. The cost of antifreeze is between that of softened water and thermal oil, and it carries the same amount of heat as softened water, so it is suitable for environments with temperatures around -30°C. After the utility model is installed on the oil well body 9, the circulation system is filled with softened water, and it can be started after connecting the power supply and fuel source. According to the outlet temperature requirements of the produced liquid of the oil well body 9, the outlet water temperature of the heater 4 is set, the operation button is started, and the equipment starts to run. The booster pump 3 sends the water in the liquid storage tank 2 into the heater 44 for heating and then sends it to the oil well body 9 corresponding to each branch for heat exchange. The uninterrupted circulation of the fluid continuously transports the heat energy of the fuel production capacity to the inside of the oil well body 9, and transfers it to the crude oil that needs to be heated, so that the oil well body 9 can achieve the purpose of smooth exploitation.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
