Description
Technical field
The utility model relates to the sub-wax-proofing apparatus of magnetic current.
Background technology
In the oil exploitation process, easy deposition wax in the oil pipeline causes like this that the petroleum pipeline internal diameter reduces, the oil transportation amount reduces greatly, and then influences oil production.The method of conventional paraffin removal has: mechanical means, thermodynamics method, chemical method and permanent-magnet waxproof technology etc., but have all that operation is frequent, expense big, have a strong impact on output and defective such as pollution is arranged.
In present stage, the oil well great majority of China also use traditional paraffin scraper method paraffin removal, time-consumingly take a lot of work inefficiency again.And external some oil fields have begun to adopt commercial bacterial preparation at present, control oil well paraffinication.In production practices; People are injected into suitable oil well shaft bottom with bacterial preparation solid-state or liquid state; Make bacterium growth and breeding and the waxy component in the oxidation crude oil constantly there, produce mesostates such as organic acid simultaneously, reduce the wax content in the crude oil; Increase the solubility of waxy component in crude oil, thereby reach the purpose of control oil well paraffinication.Be that its factor of this method affect is too many, success rate is very low, is difficult to produce a desired effect in the condition of work and geographical conditions of China.
In addition; Also has a kind of indirect paraffin removal method; At first, scientific and technical personnel utilize the periodic duty liquid in the heat exchange coil airtight in solar energy (also can utilize other low price energy such as underground heat) the heating in crude oil storage tank, and hydraulic fluid is given the crude oil in the storage tank with thermal energy transfer; Then, the crude oil that will heat again pumps into oil reservoir, and the residual crude oil in the heating oil reservoir descends its viscosity, improves oil recovery factor.But this method must be provided with oil storage tank flatly or near many mouthfuls of producing wells, is used for interim the storage from the crude oil of oil well output.Strengthened the capital construction input.
Summary of the invention
The utility model provides a kind of magnetic current wax-proofing apparatus in order to overcome above-mentioned deficiency.The power supply of employing pulse direct current utilizes electromagnetic field to carry out the sub-wax-proofing apparatus of magnetic current of wax control.
The utility model realizes that the technical scheme that above-mentioned order is taked is; The sub-wax-proofing apparatus of a kind of magnetic current; It comprises: sub-conversion equipment of magnetic current and supply unit, the sub-conversion equipment of magnetic current are included in pipeline external surface and twine empire cloth, at least one coil of installing at the external surface of empire cloth; Pipe ends is connected with oil well pipe respectively, and coil is connected with supply unit.
Described empire cloth is a colloidality insulation vacuum paint dipping.
Described coil is that the segmentation of multiply high intensity magnet-wire is entwined.
Be provided with control circuit and control panel in the described supply unit; In control circuit; Controller is connected with circuits for triggering, and circuits for triggering connect controllable rectifier module, and short-circuit protection circuit is connected with controllable rectifier module; On controllable rectifier module and circuit that inductance coil is connected; Be provided with electric current indication and voltage sampling circuit, voltage sampling circuit is connected with circuits for triggering through current feedback circuit, and inductance coil connects temperature sampling circuit and is connected with controller through temperature feedback circuit; On controller, be connected with indicating fault and electric current given circuit in addition respectively, control panel is provided with input wires terminal and output wiring terminal and trouble light, guard lamp, power supply indicator.
The sub-wax-proofing apparatus of the magnetic current of the utility model; Be to utilize magnetic field to carry out the device of wax control; There are not devices such as coil, probe, magnetic net in the fluid; There is not obstacle in flowing of convection cell, and the sub-solenoid level of magnetic current distributes and structure directly influences its thermonuclear distribution and impedance, and then influences the generation in magnetic field.The coil that the utility model adopts the segmentation of multiply high intensity magnet-wire to twine is to solve the concentrated problem of thermonuclear and the problem of impedance matching.Electromagnetic switching device is by stainless steel pipe; Two ends are equipped with respective flange and are welded; Be surrounded by the thick heat conductive insulating cloth of one deck 1.4～0.5mm in the steel pipe outside; Can make the electrical insulation of coil and tube wall, and utilize thermal conductivity help coil, make part pass through the fluid removal in the steel pipe by the heat that inductance coil produces through the tube wall heat radiation.
Utilize high-performance electromagnetism transform device to set up a high-intensity magnetic field, this magnetic field produces strong incentive action to paraffin molecule.One of which, the paraffin particle has negative electrical charge, and after high-intensity magnetic field was handled, the paraffin particle was under the effect of induced field, and its molecular separating force is interfered, and no longer arranges by original rule, has suppressed the brilliant growth of wax, has slowed down the wax crystal process, reaches the purpose of wax control.Its two, can interrupt the hydrogen bond of paraffin down in certain intensity magnetic field effect, change the strong angle of paraffin or strong intensity, make it be difficult for constituting skeleton, destroyed the coalescence of wax intergranular, make that wax is brilliant to be difficult for gathering, reach the purpose of wax control.
Because the variation of operating ambient temperature has produced the problem of expanding with heat and contract with cold; O is exerted an influence, and temperature raises and reduces and all makes solenoid produce stress, produces for fear of stress; The utility model adopts the insulating layer of colloidality insulating paint, has improved its serviceability temperature scope.
The beneficial effect of the utility model is: under the effect of the sub-induction force of magnetic current; The paraffin molecule electroneutralization, thus reduce attached to the probability on the tubing wall, if near well mouth of oil well, load onto this device; Oil stream polarization meeting has a reaction force to the liquid from the shaft bottom; Its reason is that it has powerful electromagnetic induction power to carbon steel tube, and paraffin molecule is come into line as oil again, strand of formation on the tubing length direction; Paraffin molecule is suspended among the former oil solution; Electromagnetic induction power can not be limited in the loop length scope, and it can wireless extension on magnetic line of force direction through the active force that produces of polarization, thereby reaches the purpose of wax control.
