Description
Technical field
The utility model relates to a kind of oil production equipment, particularly a kind of oil field multi-magnetic field constant temperature energy-saving electromagnetic de-waxing apparatus.
Background technology
The n-alkane of carbon number 16-64 becomes wax, and at normal temperatures, pure wax is the slightly transparent crystalline solid of white, and density is 880-905kg/m
3, fusing point 49-60 ℃.Under the oil reservoir high-temperature and high-pressure conditions, wax contained in the oil is dissolved in the crude oil.When oil extraction, crude oil has well shaft, rises to the flow process of well head from the shaft bottom from the oilbearing stratum inflow, pressure and temperature reduces gradually, and solution gas is constantly separated out, when temperature and pressure is reduced to wax precipitation point, the wax that is dissolved in the crude oil is separated out with crystal form, the molecules of wax begins to form tridimensional network to surface of solids diffusivity, and its crystal growth is laminar or block, assemble and be deposited on the tube wall, formed the wax deposition phenomenon.Wax deposition causes the crude stream diameter of threading a pipe to reduce, and oil flow resistance increases, and can make oil well produce the wax resistance when serious, causes the oil well underproduction even stopping production.
China's crude oil paraffin content surpass 10% account for 90%, the paraffin content of most of crude oil is all more than 20%, as Daqing oil field paraffin content 26.2%, North China Oilfield 21.2%, Shengli Oil Field 20.8%, Zhongyuan Oil Field 21.4%, Jilin Oil Field 22.3%, South China Sea Oilfield 20.5%, oil field, Nanyang 30.9%, Shen Bei oil field 40.9%.

Magnetic paraffin control technology and device development test are carried out early in China, all make of neodymium iron boron or Rare-Earth Cobalt magnetic material at present.Magnetic paraffin control is to utilize magnetic field to act on the wax molecule, and the power phase mutual interference of the sub-molecule of induced magnetic moment also destroys the orientation of drawing molecule moment attraction, dispersion force when having slackened the wax molecular crystalline, suppress the growth of wax crystallization, stop the gathering of wax crystallization body, reach the purpose and the effect of wax control.
Though this class magnetic wax control device has wax control result preferably, cause magnetic to weaken along with the raising of crude oil temperature and cause the wax control result variation, at 80 ℃ of environment, magnetic intensity reduces by 30% as Nd-Fe-Bo permanent magnet material.
The clear wax control of using at present of electromagnetism in addition is coil of coiling outside one section nonmagnetic substance pipeline, adds that electric current produces magnetic field, reaches the effect of the clear wax control of magnetic.The clear wax control of electromagnetism can not produce the magnetic decline.But electric current and magnetic field intensity are constant.Magnetic field deficiency that electric current is little, clear wax control result is poor; Electric current is big, has both wasted a large amount of electric energy, and long-time big current work, very easily produces high temperature and burns coil.With the Daqing oil field is example, and the power consumption that removes wax control has accounted for the 25-30% of cost of crude oil production.
In addition, the electromagnetism of using removes wax control device at present, all needs the peripheral hardware electric control box, and this has increased makes the cost of installing, and has increased the fault odds, has reduced theft protection, vandal-proof security performance again.
