The utility model has the advantages of enhancing petroleum mass and yield, energy saving, without polluting environment, strong adaptability, automatic temperature control, large power adjustable range, convenient operation, fast heating up, and long service life.
Description
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.
