Description

Oil well pump antiscale abrasionproof exhausting-aid device
Technical field:
The utility model relates to the oil well pump antiscale abrasionproof that a kind of picking device that helps of drawing liquid body, particularly a kind of oil field use to be helpedTake out device.
Background technology:
At present, the oil well pump that the each oil extraction in oil field of China uses is that plunger pumps and reaches oil pumping order in pump barrel, between plunger and pump barrel, certainly exist certain interval, in lifting process, leakage is serious, causes negative pressure in pump barrel to reduce, shadowRing oil production, and need very large lifting force; In oil recovery process, oil, water and other impurity mix, easily at plunger andPump barrel surface scale, poly-wax, make plunger easy to wear, needs often to change plunger; In pump barrel repair process, need Chemical cleaning andCause the waste of manpower and materials, polluted again environment, affected greatly oil recovery efficiency.
Summary of the invention:
The utility model is just to provide a kind of antiscale, wax control, anti-eccentric wear, anti-leak, increases oil pumping barrel negative pressure, to reachHelp and take out, increase oil production, extend the oil well pump life-span, thereby reduce well workover frequency, the antiscale that can increase substantially production efficiency is anti-Mill exhausting-aid device.
The purpose of this utility model is achieved in that a kind of oil well pump antiscale abrasionproof exhausting-aid device, formed by exhausting-aid device, itsThe oil-feed nose end and/or the fuel-displaced nose end that are characterised in that described exhausting-aid device are installed a stainless steel tube, are equipped with sacrificial in stainless steel tubeDomestic animal anode and high strength magnet, sacrificial anode and high strength magnet are combined by designing requirement.
Sacrificial anode described in the utility model and high strength magnet all adopt circular built-up construction, insert high strength in ringAfter metal bar, with the welding of stainless steel tube two ends, sacrificial anode is made up of two semicircles, and length is not less than 600mm, high strength magnetBe made up of at least 4 road magnet rings, every ring is at least made up of 3 blocks of magnet.
There is screw thread at described stainless steel tube two ends, and wherein one end is connected with exhausting-aid device.
In described stainless steel tube, be connected with exhausting-aid device near high strength magnet end.
In described stainless steel tube, be connected with the oil-feed nose end of exhausting-aid device near high strength magnet end.
In described exhausting-aid device, the external cylindrical surface in centre position is equipped with alloy wear-resisting ring, alloy wear-resisting ring at least two rings.
The utility model compared with prior art has the following advantages:
Because the oil-feed nose end and/or the fuel-displaced nose end that have adopted exhausting-aid device are installed a stainless steel tube, stainless steel tube is in-builtThere are sacrificial anode and high strength magnet, the version that sacrificial anode and high strength magnet are combined by designing requirement, because ofAnd:
1, sacrificial anode is the better preserved of the anti-eccentric wear of electrochemical anti-corrosive; It is from anode bodies by working fluid asElectrolyte provides a cathode current to realize cathodic protection to the parts of protected oil pumping barrel and friction, reaches anticorrosion and does not tieDirt, the life-span of improving oil well pump;
2, high strength magnet passes through science design, rational deployment, field intensity is high, magnetic journey long, have vertical, parallel magnetic field district, againHave high and low field regions, central magnetic field more than 8000 Gausses, thereby broken continuous phase, decentralized photo, the liquid in crude oil mediumWith the nucleus structure of solid-phase, play the effect that prevents paraffin cohesion, thereby reached the object of antiscale wax control;
3, exhausting-aid device plays crude oil is not refluxed, and the effect that can only rise has reached and helped the object of taking out, thereby significantly carriedHigh oil production.
More than combine, become a product, thereby reached in process of production antiscale, wax control, anti-eccentric wear, anti-Leak, increase oil pumping barrel negative pressure, take out to reach to help, increase oil production, extend the oil well pump life-span, thereby reduce well workover frequency,Can increase substantially production efficiency; If multistage use, is equivalent to reduce oil well depth, thereby reduce lifting power, canSignificantly reduce power consumption.
Brief description of the drawings:
Fig. 1 is the utility model concrete structure schematic diagram
1, sacrificial anode 2, high strength magnet 3, stainless steel tube 4, fuel feed hole 5, alloy wear-resisting ring 6, steel ball 7, helpTake out device 8, oil outlet 9, righting sealing ring
Detailed description of the invention:
Sacrificial anode 1 and high strength magnet 2 all adopt circular built-up construction, and sacrificial anode 1 is made up of two semicircles, lengthBe not less than 600mm, high strength magnet 2 is made up of at least 4 road magnet rings, and every ring is at least made up of 3 blocks of magnet, sacrificial anode 1 HeHigh strength magnet 2 is assemblied in stainless steel tube 3 by designing requirement layout, and stainless steel tube 3 tube walls have equally distributed circular hole; SacrificialAfter inserting high duty metal rod in the associative ring of domestic animal anode 1 and high strength magnet 2, weld high duty metal with stainless steel tube two endsRod two ends are helicitic texture, and its one end is connected with fuel feed hole 4 ends and/or oil outlet 8 ends of exhausting-aid device 7, and best mode is stainlessSteel pipe 3 is interior to be connected with fuel feed hole 4 ends of exhausting-aid device 7 near high strength magnet 2 ends, and exhausting-aid device 7 adopts one way poppet valve, outside itThe face of cylinder symmetrical processing fuel feed hole 4 and oil outlet 8, be reducing through hole between fuel feed hole 4 and oil outlet 8, in reducing through hole, putsHave steel ball 6, the two ends of exhausting-aid device 7 have connecting thread to be connected with one end of stainless steel tube 3, therebetween the external cylindrical surface at position dressHave alloy wear-resisting ring 5, alloy wear-resisting ring 5 at least two rings, install righting sealing ring 9 on exhausting-aid device 7 external cylindrical surfaces at its two ends.
When use, product of the present utility model is arranged on oil pump plunger piston or sucker rod, as required can multistage companyConnect, when installation, general stainless steel tube 3 under, exhausting-aid device 7 is upper, when oil pumping, in the time that sucker rod sinks, crude oil passes through fuel feed hole 4Push steel ball 6 open and enter in oil pumping barrel by oil outlet 8, by the effect of alloy wear-resisting ring 5, reach the effect of abrasionproof, crude oilDuring through stainless steel tube 3, by the sacrificial anode 1 in pipe, sacrificial anode 1 discharges cathode current, and the parts of protection friction, reachAnticorrosion non-scaling, then by high strength magnet 2, by the circular hole on stainless steel tube 3, discharge the magnetic line of force, prevent paraffin cohesion, reachArrived the object of antiscale wax control, thereby realized antiscale, wax control, anti-eccentric wear, anti-leak, in the time that sucker rod rises, steel ball 6 cuts out, and closesClose oil-in, crude oil is not refluxed, can only rise, reached and helped the object of taking out.
