Description
The utility model relates to petroleum collection, a kind of specifically petroleum thermal recovery production aid device that uses direct current heating in medium frequency and high-intensity magnetic field to combine.
The auxiliary equipment that multiple thermal recovery is arranged is at present both at home and abroad injected HCS as using steam boiler to the down-hole, uses heating cable, resistance wire formula, merit coil type or the like frequently, but all undesirable.For example, steam boiler is annotated dry gas to the down-hole, it all can not reach its service condition to outlying well and the deep-well below 1700 meters, one is that remote pipeline is restricted, two for not reaching notes to the needed pressure of deep-well, and oil reservoir there is pollution, the steam cooling can become water, and water has been sealed fuel-displaced micropore, so the formation contaminant problem is arranged, and cost height, life-span is short, just needs about three months greatly to annotate once again, because of there is back pressure the down-hole, so all need inject 1500-2000 cubic meter steam at every turn, costly.Heating cable for another example, power consumption is big, thermal conductivity is low, and the cost height does not gradually have market in oil recovery.For another, resistance wire formula heater is because of itself being exactly the product of power consumption, uncontrollable it is temperature required, power can't be regulated, be absolutely unsafe, and the accident of scaling loss cable occurs, simultaneously because of regulating power, may make oil well casing be subjected to Gao Re and modification causes oil well to scrap.
Merit is the coil type heater frequently, its function is better than above three kinds of products, but because it has adopted interchange merit formula eddy-current heating principle frequently, so it is big power consumption to have occurred, need 35KW-50KW, it is too high to increase cost for oil production, and because of adopting AC power, the remote conveying, the electric current and voltage loss is big, and three-phase is often unbalance, is converted into thermal source because of the magnetic field that produces in managing again, and can not oil be magnetized, thereby make oil after the heating when not being pumped to ground, just become the cured type viscous crude of knot once more, though this equipment is better slightly than miscellaneous equipment, but its shortcoming can not solve again, so still undesirable.
The purpose of this utility model provides a kind of oil production aid device, the heating of solution down-hole, viscous crude dilute under the weighing apparatus fixed temperature, and the cured problem of solution knot, reduce power consumption, reduce cost for oil production, solve the problem of husky resistance well, prolong the well recovery time limit, the control of realization automated power, the problem of production aid device unused power when solving down-hole feed flow deficiency is so that energy conservation.
The purpose of this utility model is achieved in that
A kind of oil production aid device, mainly heating magnetizing tube down by Ground Control case and oil well forms, the input power supply of Ground Control case is by automatic air-break switch, through the integrated circuit block rectification is D.C. regulated power supply, be provided with power governor in this control cabinet, thermoregulator, electric current, voltmeter, current transformer, adjusting knob, signal feedback cable etc. is connected with suitable circuit.
The structure of described down-hole heating magnetizing tube comprises:
Pipe in one heat transfer is A

One sensor wrap, be connected in closed casing top, converter plant is housed in it, flow transmitter, temperature pick up, in the endoporus of pipe, the sensor wrap top was equiped with cable connector in the probe of described flow transmitter and temperature pick up stretched into and conducts heat, and the power supply of described magnetizing tube is connected with the Ground Control case through this cable connector with the lead of various feedback signals.
Operating principle of the present utility model:
1, the three-phase alternating current that uses with the oil field becomes direct current, has solved long voltage, electric current during apart from transmission of electric energy and reduce and unbalance problem after rectification;
2, adopt the down-hole frequency conversion, come oil reservoir is heated with the principle of heating in medium frequency, it is low to have power consumption, the effect that the thermal efficiency is high, when power fixes on 18KW, the thermal efficiency just can be up to nearly 300 degree, per hour energy charge is only 12.60 yuans, than the equipment of other type, has tangible reduction effect.
3, in order to solve the cured problem in the viscous crude, the magnetizing tube of the utility model production aid device has been installed permanent magnet steel, magnetize cured, because of its afterbody at the down-hole magnetizing tube, all oil that draw up are all flowed through in its magnetic field circle, and itself just be immersed in the oil reservoir middle part, oil is magnetized for a long time, effectively prolonged cured time of setting again.
4; flow transmitter has been installed in the magnetizing tube; when the husky proportion that contains in the oil surpass to be set when requiring; flow transmitter is given the automated power adjuster with signal feedback; production aid device will temporarily quit work this moment; so that sand floats; make oily retrogradation; utilize viscous crude can take away husky principle come clear husky, when reaching when setting the oil recovery standard, the production aid device work of will resetting automatically; thereby solved the sand prevention problem; prolonged the time limit of husky resistance well, thermocouple has been installed, on the magnetizing tube after temperature reaches design temperature; signal feedback thermostat and power automatic regulator; carry out autostop, temperature automatically controlled, can keep the temperature of downhole oil; prevented from again to waste can and temperature overheating make the problem of oil gas waste crude oil.
Have through hole on the magnetizing tube; be to hold oil for the down-hole; when liquid level is lower than magnetizing tube; in the air inflow pipe; make oil can not be drawn into oil pipe; this moment, flow transmitter was given the automated power adjuster with signal feedback; with autostop, both saved the energy, kept the down-hole to have enough crude oil to do the heat conduction source again, because of the thermal source of production aid device can form the thermosol pond by down-hole crude oil; and the thermal source of bath will be to oil reservoir diffusion all around; thereby play de-plugging, increased the speed that oil sources flows to oil well, and incremental oil production; when liquid level surpasses when holding oilhole signal sensing instruction once more.Start auto restore facility, solved down-hole thermal source diffusion problem of unstable, because this novel production aid device is after adopting artificial the setting, equipment is by setting instruction operation automatically, so have simple, convenience operation are installed, with the tangible difference and perfect of having compared of other kind equipment.
In sum, be not difficult to find out, with at the part difficulty that exists in recovering the oil, be resolved, finished problem to be solved in the utility model, the utility model is compared with the equipment of other type, have energy conservation, the efficient height, adjustable extent is big, stablize the down-hole heating-up temperature, prevent to tie cured, magnetic field is strong, prevents drift sand resistance well, with kept the down-hole oil reservoir can obtain stable heating, forced the amount of flow of oil in well, the power when having prevented from not have oil wastes, and has reduced cost for oil production, guaranteed safety, simple to operate and satisfactory for result.
