Description

Electromagnetic heating device for deep-well petroleum

The utility model relates to special equipment---the deep-well oil electromagnetic heater of a kind of oil field aboveground down-hole petroleum pipeline and the heating of deep-well oil reservoir.

At present, the domestic petroleum heater has heating of resistance fiber tube and far infrared elema heater etc., but does not have deep-well oil reservoir heater.The utility model deep-well oil electromagnetic heater adopts the principle of electromagnetic induction to make calandria form eddy current and produces the purpose that heat reaches heating, solves the heating problems of heating of oil field deep well oil reservoir and ground petroleum pipeline.

The purpose of this utility model is all can obtain changing oil temperature in the oil pipeline for the marginal well that makes the oil field, heavy oil wells, high wax well, hibernation etc., reduce wellhead back pressure, the liquid oils of oil well output is circulated in thermal field, improve the output quantity of crude oil, a kind of deep-well oil electromagnetic heater is provided.

The utility model deep-well oil electromagnetic heater content Description:

The utility model deep-well oil electromagnetic heater is characterized in that being made of surface em heater, controller, deep-well oil reservoir electromagnetic heater, oil pick-up tube; At anterior device one controller of control cabinet, posterior means one surface em heater, deep-well oil reservoir electromagnetic heater is connected on the oil pick-up tube, and oil pick-up tube and surface em heater link together; Controller is made up of thyristor, power governor, adjustment indicator, voltmeter, ammeter etc., use the three-phase alternating-current supply of crude oil well, deliver to the heater balanced load through air automatic switch, controllable silicon, utilize temperature measurement circuit to realize the automatic adjusting of power, the heating-up temperature of control silicon controlled size of current decision oil.

The utility model deep-well oil electromagnetic heater has simple installation, compliance is strong, temperature automatically controlled, power regulating range is big, can in 0～100 kilowatt, regulate according to user's needs, temperature regulating range is wide, characteristics such as simple to operate, quick heating, thermal efficiency height, low in energy consumption, long service life.Can be widely used in marginal well, heavy oil wells, high wax well, hibernation well and not have associated gas, stripper well, high-yield well etc., all can play the oil temperature that changes in the oil pipeline, reduce wellhead back pressure, the liquid oils of oil well output is circulated in thermal field improve the effects such as output flow of crude oil, can improve the quality and the output of oil, save the energy, free from environmental pollution.

Embodiment:

Fig. 1 is a deep-well oil electromagnetic heater overall structure schematic diagram;

Fig. 2 is the control cabinet structural representation;

Fig. 3 is a surface em heater structure schematic diagram;

Fig. 4 is a deep-well oil reservoir electromagnetic heater structural representation.

Among Fig. 1: 1 is control cabinet; 2 is the surface em heater; 3 is controller; 4 is oil pick-up tube; 5 is deep-well oil reservoir electromagnetic heater.(Fig. 2) at anterior device one controller 3 of control cabinet 1, posterior means one surface em heater 2, (Fig. 1) deep-well oil reservoir electromagnetic heater 5 is connected on the oil pick-up tube 4, oil pick-up tube 4 and surface em heater 2 controller 3 that links together is by thyristor, power governor, the adjustment indicator, voltmeter, compositions such as ammeter, use the three-phase alternating-current supply of crude oil well, through the air automatic switch, controllable silicon is delivered to the heater balanced load, utilize temperature measurement circuit to realize the automatic adjusting of power, control silicon controlled size of current, the heating-up temperature of decision oil.(Fig. 3) surface em heater 2 is the shape made with steel pipe such as snakelike heating tube 6, the skin of heating tube wall is made a sealant 7 with alumina silicate insulation and thermal insulation heat insulating material, in the outside of sealant 7 heater coils 8 by the copper cash coiled, there is one deck covering tape its outside, temperature pick up 9 is inserted in the tube wall of heating tube 6 outlets, the power line of heater coil 8 is connected with controller 3 circuits, when three-phase alternating current passes through heater coil 8, in heater coil 8, produce high-intensity magnetic field, pass sealant 7, in heating tube 6 walls, form eddy current, make the heating tube wall produce 200 °～800 ℃ high temperature, the big more magnetic field of electric current is strong more, and it is high more that the heat pipe wall temperature is forced in magnetic field more, by the size of controller 3 control electric currents, form automatic temperature-adjusting control and power adjustment.(Fig. 4) deep-well oil reservoir electromagnetic heater is a heating tube 10 of making the straight tube shape with steel pipe, the insulation and thermal insulation thermal-insulating sealing layer 11 that the tube wall skin of heating tube 10 has an aluminosilicate material to make, the outside of sealant is the heater coil 12 that a usefulness copper cash turns to, there is one deck covering tape its outside, outermost layer is a sleeve pipe 13, can prevent that You Heshui from entering in the heater, heater coil electric current by the time heat that produces pass to by sleeve pipe and carry out preheating in the oil reservoir, heated oil is heated once more by the surface em heater after being extracted into ground, enters petroleum transportation pipeline then.
