Abstract
The utility model relates to an oil extraction electromagnetic heating device with frequency conversion, comprising an inner tube for the heater, an electromagnetic loop sheathed on the inner tube of the heater and an outer tube for the heater outside the electromagnetic loop; a connecting screw is arranged at two ends of the inner tube for the heater and is connected with an oil tube. The utility model has advantages of energy and electricity saving, high thermal efficiency, no corrosion, long service life. The utility model can be applicable broadly, to machine pumping wells, electric pump wells, flowing wells, gas lift wells, water injection wells and ground oil pipelines.
Description
Technical field
The utility model relates to a kind of frequency conversion oil recovery electromagnetic heater
Technical background
The petroleum industry extraction industry exists the difficult problem of exploitation to hyposmosis, the high viscous crude that coagulates at present, conventional electric heating technology (as the electrical heating hollow rod) exists the problem that power consumption is high, the thermal efficiency is low, fault rate is high, thereby increase crude oil cost (fault can increase a large amount of operating costs) greatly, and its with the galvano-cautery phenomenon, have a strong impact on the application life and the oil well output of oil pipe and sucker rod.In addition, limit by its structure, can not make crude oil not advance pump smoothly, influence output heating crude oil under the pump.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of thermal efficiency height, no burn into long service life also can be to the frequency conversion oil recovery electromagnetic heater of heating crude oil under the pump.
The utility model adopts following technical scheme: a kind of frequency conversion oil recovery electromagnetic heater, it comprises pipe in the heater, is sleeved on the electromagnetic coil on the interior pipe of heater and is arranged on the outer heater outer tube of electromagnetic coil that the two ends of pipe are provided with the thread that is connected with oil pipe in the heater.
Its electromagnetic coil of the utility model is connected with the variable-frequency power sources circuit arrangement by cable conductor.The utility model cable conductor is fixed on the oil pipe by the cable clip.
Good effect of the present utility model is as follows:
The utility model adopts the variable-frequency electromagnetic heating technique, the oil pipe self-heating, and energy saving, thermal efficiency height does not have corrosion, long service life.
The utility model directly is connected with oil pipe, is in quiescent operation, and the disconnected fault of taking off is difficult for taking place.
The utility model can be installed under the oil well pump, makes under the pump to advance pump smoothly after the crude oil intensification, increases crude output greatly.
The utility model is applied widely, machine is taken out well, electric pump well, flowing well, gas-lift well, water injection well and ground oil pipeline all can use.
The utility model is carried out Digital Control fully, can design voluntarily according to hole condition, and the assurance oil well is produced in the best condition.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the utility model user mode schematic diagram.
In the accompanying drawings: pipe, 2 heater outer tubes, 3 electromagnetic coils, 4 threads, 5 variable-frequency power sources circuit arrangements, 6 cable conductors, 7 electromagnetic heaters, 8 screw thread box cuplings, 9 oil pipes, 10 cable clips, 11 oil well pumps, 12 oil well casings in 1 heater.
The specific embodiment
Shown in accompanying drawing 1,2, the two ends of pipe 1 are provided with thread 4 in the utility model heater, electromagnetic heater 7 can be installed in the joint of two oil pipes 9 by thread 4, as shown in Figure 2, the utility model electromagnetic heater 7 can be installed in oil well pump 11 times, advance pump smoothly after making the crude oil intensification under the oil well pump 11, improve crude output greatly.The utility model variable-frequency power sources circuit arrangement 5 is at first with three-phase 380V, 50Hz power frequency electricity converts intermediate frequency and adjustable single-phase electricity output to, through each electromagnetic heater 7 under the cable conductor 6 connection oil wells, electromagnetic heater 7 is by connecing screw thread 4 and screw thread box cupling 8 connection oil pipes 9 then, after cable conductor 6 is linked into variable-frequency power sources circuit arrangement 5 interior formation loops by the cable clip 10 on the oil pipe 9, energising electromagnetic coil 3 produces magnetic field and is absorbed by pipe in the heater 1, generation electromagnetism heat, the crude oil of pipe 1 in the heater of flowing through is heated up, thereby guarantee the efficient low-consume ordinary production.Up and down heat penetration is unlimited to pump for the utility model, and it is not enough to overcome on the pump heat penetration, the shortcoming that pump can not heat down.Make full use of electromagnetism heating principle, can save a large amount of electric energy, and can improve the thermal efficiency, also can prevent the generation of galvano-cautery phenomenon, prolong the application life of oil pipe and sucker rod, not only effectively reduce and resolve the generation of taking off fault, improve the operating efficiency of oil well, and saved a large amount of operating costs.
