Oil well paraffinication is the problem of existing for a long time in oilfield development process, when crude oil is extracted into ground from underground, due to molten
Solve gas effusion and expansion and crude oil temperature is gradually reduced, when temperature is down to below wax precipitation point, wax in crystalline form from
Separated out in crude oil.Temperature, pressure continue to reduce, gas evolution, crystallize the wax agglomeration of precipitation, form wax crystal.Wax crystal
It is deposited on the surface of pipeline and equipment etc., causes pit shaft to narrow, oil well output reduces, and oil pipe can be also blocked when serious and causes oil
Well stops production.
Numerous studies show：Reduction of the crude oil to the solubility with temperature of wax and reduce, when temperature is reduced to crude oil to wax
The solubility paraffin content that is less than crude oil a certain value when, the wax dissolved in crude oil just starts to separate out, temperature when wax starts to separate out
Degree becomes the primary crystallization temperature or wax precipitation point of wax.
Wax removal technology mainly has two kinds of " mechanical paraffin removal ", " heating power wax removal " at present, and mechanical paraffin removal method is to scrape oil removing with scraping blade
Inside pipe wall wax crystallization, is the paraffin removal method after wax moulding, and the method not can effectively prevent the formation of paraffin, later stage paraffin removal shape
Into wax stone, the problem of equally existing plugging；Heating power wax removal mainly circulates hot water or deep fat to improve pit shaft in the wellbore
Temperature achieving the purpose that wax, such a method need to pour into hot water or deep fat into pit shaft, then shut down and wait；The above common two
Kind method is implemented bothersome laborious there are security risk, it is impossible to accomplishes uninterruptedly to produce, efficiency is low.
Utility model content
The purpose of this utility model is that the defects of being directed to the prior art and deficiency, there is provided a kind of simple in structure, design is closed
Reason, the quick anti-heating device for paraffin removal of oil well easy to use, its sensitiveness for paraffin to temperature, by lifting oil pipe temperature
It is uncrystallizable to reach paraffin, so that cannot be into wax, while any other material need not be added into pit shaft, without shutdown etc.
Treat, use with the opening, temperature-controllable；Reach continuous production, improve just efficient.
To achieve the above object, the technical solution adopted in the utility model is：It includes cylindricality calandria, oil pick-up tube, consolidates
Determine fastener, cable coupling box, data connecting line, transformer, switch board；It has been placed equidistant with the outside of the oil pick-up tube several solid
Determine fastener, cylindricality calandria is fixed on the lateral wall of oil pick-up tube by fixed fastener；The top of the cylindricality calandria and electricity
Cable terminal box connects, and cable coupling box is connected by data connecting line with transformer, and transformer passes through data connecting line and control
Cabinet connects.
Preferably, a temperature sensor, and temperature are placed with every a distance on the tube wall of the oil pick-up tube
Sensor is fixed by fixed fastener.
Preferably, the transformer, switch board form power supply unit, power supply unit is electrodeless power regulating pattern, can be
Zero to adjusting heating power between maximum power.
Preferably, the part that the cylindricality calandria stretches out oil pick-up tube is provided with suspender, to fix cylindricality heating
Body.
With the above structure, the utility model has the beneficial effect that：A kind of oil well described in the utility model is quickly anti-clear
Wax heating unit, it is for paraffin to the sensitiveness of temperature, and by lifting oil pipe temperature, to reach paraffin uncrystallizable, so that cannot
Into wax, while any other material need not be added into pit shaft, wait, use with the opening, temperature-controllable without shutting down；Reach company
Continuous production, is improved just efficient.The utility model has the advantages that simple in structure, it is reasonable to set, low manufacture cost.
