It is not related to a kind of wax removal wax control electric heater unit of intelligent digital hollow rod.
Background technology
In China's oil exploitation, high solidifying oil, the ratio of heavy oil wells account for a large portion, this kind of well viscosity of crude height,
Freezing point is high, density is big, paraffin content is high, be difficult to exploit.For using hollow rod viscous crude producing well, because viscous crude holds very much more
Easily wax deposition, so hollow rod and pit shaft, often because internal wax deposition, blockage phenomenon, directly affect manufacturing schedule, with
When wax removal operation also bother very much, the serious exploitation restricting viscous crude producing well.For hollow rod and pit shaft often because interior
More than portion's wax deposition by the way of dosing and thermal washing, both approaches can there is certain injury to cable, and wax removal is not thorough, clearly
Frequently, integrated cost is costly for wax number of times.Occurred in that the new device of Electromagnetical anti-wax machine in recent years, due to the anti-wax product of electromagnetism
The scope of the action of a magnetic field decay with the increase of distance, due to the difference of every mouthful of well wax deposition point in each oily area, can cause
As usual the phenomenon separating out in the outer wax of wax deposition point and sphere of action.The magnetic field intensity of another aspect Electromagnetical anti-wax machine is in oil
Paraffin content is targetedly arranged, and cannot be done due to the uncertainty of each regional every mouthful of well oil paraffin content and targetedly adjust,
So also having the precipitation of wax crystal, electromagnetism wax control, only as reducing wax precipitation device, can not have been made for wax deposition
The scavenging action of effect.
Content of the invention
Technical problem to be solved in the utility model is a kind of the clear of intelligent digital hollow rod of offer
Wax wax control electric heater unit is it is adaptable to hollow rod electrical heating is recovered the oil.The heat resistance of device can effectively prevent well hollow taking out
Beam hanger and well bore wall wax deposition are it is ensured that viscous crude, height coagulate the mining progress of oil producing well.
For achieving the above object, this utility model employs the following technical solutions realization：
A kind of wax removal wax control electric heater unit of intelligent digital hollow rod, including administration of power supply, hollow oil pumping
Bar, described administration of power supply includes frequency conversion electrical control cabinet and service cable, and frequency conversion electrical control cabinet connects service cable and hollow rod hangs
Connect device, hollow rod hangs and connects device positioned at hollow rod upper end, and insulated heater wire penetrates in hollow rod, takes out by hollow
Beam hanger hangs and connects device connection administration of power supply, and the lower end of insulated heater wire is provided with the terminal organ of packaging insulating heater wire；Described insulation adds
Hot line is made up of insulating barrier, conductive layer, steel wire pulling force rope three part, and the conductive layer that fine copper wire is constituted is by the steel wire at the center of wrapping up
Pulling force rope, insulating barrier is wrapped in outside steel wire pulling force rope and conductive layer.
Described insulating layer material is mineral insulating material magnesia powder or politef.
Described frequency conversion electrical control cabinet includes intelligent digitalized automatic control system.
Compared with prior art, the beneficial effects of the utility model are：
1. this utility model adopts insulated heater wire using heat effect principle and kelvin effect principle, in conjunction with frequency conversion intelligent electricity
Control cabinet controls, and has and is hardly damaged, Based Intelligent Control heating-up temperature is constant, the features such as clear, wax removing effect is obvious.
2. insulated heater wire lower end is provided with terminal organ it is easy to decentralization, accurate positioning, directly can be entered hollow rod down
In, carry out whole heating to entering section under oil well, and the heat energy overwhelming majority is changed into oil heat energy, makes OIH temperature rise, viscosity
Reduce, heating wax removing effect is good.Because heated viscosity of crude reduces and R a T no wax deposition, tube chamber is kept to lead to
Freely, tube wall is smooth, greatly reduces the resistance of motion in oil pipe for the crude oil, reduces load and the fault rate of oil well pump, and raising is taken out
Oil pumping effect of oil machine, save energy, shortens the time between overhauls(TBO) of oil well.
