Description
Provided by the present invention is a kind ofly to prevent paraffin separate out and agglutinate magnetizing assembly on tubing wall by physical method.
Before the present invention made, oil self contained 1% to 50% paraffin, and contained paraffin is separated out easily and agglutinated on tubing wall when temperature descends, the oil circuit section is reduced, block oil flow channel, have a strong impact on the yielding capacity and the transporting velocity of oil, cause the stop-spraying accident.The method of the long-pending wax of traditional removing is to adopt the mechanical type wax wiper.By the scraping blade device paraffin in the hundreds of rice well casing is scraped and to take well head out of.Long-pending wax also will feed hot water when serious, heat steam is heated, or injects methods such as chemical substance or the heating of input resistance wire and clean.Some oil field oil contains the wax height, causes output to descend by long-pending wax, often wax removal, well-flushing.And removing paraffin and washing well must all stop production, and has directly influenced production.Also there is same problem in transport pipe to oil, and especially when ambient temperature was low, oil flow is difficulty more.The measure that the present invention takes before making is to be provided with along the line that several large pumping stations are heated, supercharging.Because equipment is huge, power is big, and consumes energy is many.
In addition, Russian Patent SU590438 discloses a kind of magnetizing assembly that prevents that paraffin is separated out in the oil, and this device is made of permanent magnet, outer sleeve and inner core tube.But the magnet of this patent is so to arrange, and promptly magnet along the circumferential direction magnetizes, and produces radial magnetic field.Magnet this is arranged with a significant disadvantages, promptly is not suitable for the rare-earth permanent magnet series material, therefore can not produce higher magnetic field.
Therefore, the object of the invention is to provide a kind of magnetic circuit to be applicable to the rare-earth permanent magnet series material, and can produce the magnetizing assembly that paraffin is separated out in the oil that prevents of higher magnetic field.
The present invention seeks to realize by the device with following structure: this device comprises: the inner core tube that is made of non-magnet material, several rare-earth permanent magnet pole pairs, each pole pair is made up of two magnetic poles, and the outer sleeve that constitutes by permeability magnetic material, described permanent magnet is a rare-earth permanent magnet, two magnetic poles of each pole pair are arranged in suction mode mutually on the same cross section of tubular axis, and the direction of magnetization of magnet is for radially, so that the magnetic direction of the working space in the direction of magnetization of described magnet and the described inner core tube is consistent, and make described working space magnetic direction vertical with oil liquid flow path direction.
Several specific embodiments of the present invention is described below with reference to accompanying drawings.
Fig. 1, be between the tubular type oil-producing well prevent the magnetizing assembly schematic representation that paraffin is separated out.
Fig. 2, prevent the magnetizing assembly schematic representation that paraffin is separated out for the suspension type oil-producing well.
Fig. 3, prevent the magnetizing assembly schematic representation that paraffin is separated out for the multi-tube transport pipe.
Fig. 4, with Fig. 5 be magnetic structure type schematic representation, wherein Fig. 4 is a face-off type magnetic circuit, Fig. 5 is the screw type magnetic circuit.
Accompanying drawing 1 is depicted as the magnetizing assembly that oil-producing well prevents that paraffin from separating out.The external diameter of this device is less than the internal diameter of borehole wall sleeve pipe 1.When this device was connected in series with the oil pipe of oil well pump top, its external diameter can be equal to or less than pipe aperture.Among the figure 2 is oil pipe.Core pipe 4 is to make with the non-magnetic material.The 5th, the permanent magnet of this device is to be made by the rare earth permanent magnet series material.6 is the shell of this device, is to be made by the good material of magnetic conductivity.7 is working space.More than 4,5,6,6 parts by scyewed joint and be welded to form this device.
Accompanying drawing 2 is depicted as the magnetizing assembly that the suspension type oil-producing well prevents that paraffin from separating out, and is identical with the former principle, the structure difference.Its external diameter is less than the well casing internal diameter; Requirement is put down in well casing and is taken out, and its internal diameter is determined by structure, requires big as far as possible.Wherein 4 is inner sleeve, made by non-magnet material, and 6 is outer sleeve, and made by permeability magnetic material, 5 is permanent magnet.In addition, in order to make this device location wing 8 is housed correct location in the down-hole.Two ends have streamlined deflector 11 up and down, and hanger 9 is equipped with in the upper end, are hung by wire rope 10, are fixed in well head, because the very little laminar condition that all is in of OIH flow velocity degree.Turbulization not, thereby it is very little to influence oil flow.This magnetizing assembly is installed not to be needed well casing is proposed outside the well.Get final product and directly this magnetizing assembly is put into well.
In the above-described embodiment, the direction of magnetization of magnet 5 is for radially, so it is consistent with the magnetic direction of working space 7, and the magnetic direction of working space is vertical with oil liquid flow path direction.Therefore, it compared with the prior art, leakage field is little, and owing to use rare-earth permanent magnet, can produce higher magnetic intensity (500 to 5000 Oersted).
More than its magnetic structures of device of three kinds of forms comprise Fig. 4 face-off type and Fig. 5 screw type.Select different magnetic structures according to different oil-field structures for use with the oil composition.Magnetic material is the rare earth permanent magnet series material.Operating temperature can adapt to 200 ℃ to 40 ℃.
Adopt provided by the present invention prevent the oil wax deposition magnetizing assembly, can prevent long-pending wax, thereby no longer need wax removal, well-flushing operation.Exempt the energy consumptions that method caused such as being used to feed hot water, steam, chemicals, electric heating, reduced the Petroleum Production cost significantly.Eliminate the stopping production that causes because of removing paraffin and washing well, improved oil worker's working condition.Improve simultaneously and speed oil, the raising oil production rate.This apparatus structure is simple, and is easy to install, do not need to safeguard, consumes energy does not guarantee the oil well continuous operation.Be applicable to oil well and transport pipe.
The present invention is used for petroleum pipeline, and the pumping plant quantity of heating is along the line reduced, thereby makes equipment investment and energy source and power consumption that heat heating and pumping plant pressurize reduces significantly.
