Abstract
A sand scraping plunger type sand-proof oil-well pump comprises a plunger, a two-way joint, a pump cylinder, an outer cylinder, a sand blocking slide valve, a fixed valve and the like. The plunger comprises a tail connector, a traveling valve, a plunger body and an oil outlet connector, the whole plunger is of an equal-diameter hard sealing sand scraping structure, a sealing section of the plunger extends upwards to a liquid discharge port of the oil outlet connector, and sand scraping chamfers are arranged on the upper portion and the lower portion of the plunger. The utility model has the advantages of simple structure, operation construction convenient operation, the down resistance of plunger is little, has the characteristic that the plunger was buried to sand prevention, sand prevention card plunger simultaneously, but wide application in high sand oil well.
Description
The utility model relates to deep-well pump, relates in particular to a kind of sand-proof oil-well pump.
Patent Office of the People's Republic of China has announced that a kind of patent No. is 86209054.7 sand control card oil well pump, mainly by urceolus, pump barrel, duplex fitting, oil drainer, and the soft or hard combined plunger is formed, purpose is the sand buried column plug that solves sand well, sand card plunger problem, but because soft seal subjects to destroy in the process of going into the well on the plunger, cause plunger can not enter pump barrel, or because after soft seal weares and teares in a short time fast on the plunger body, lose the effect of strike-ofing, cause sand card plunger, therefore, this pump can only solve sand buried column plug problem, but can not reach the purpose that solves pump sand card plunger problem.
The purpose of this utility model provides and had a kind ofly not only overcome the problem that prior art exists but also have that sand control buries, sand control card, low cost, help improving the new type of sand prevention oil well pump of pump efficiency, energy saving.
The purpose of this utility model reaches like this: a kind of plunger type sand-proof oil-well pump of strike-ofing comprises plunger, duplex fitting, pump barrel, urceolus, sand block guiding valve, standing valve etc.Plunger comprises afterbody joint, traveling valve, plunger body and delivery connection, whole is the isometrical hard sealing structure of strike-ofing, and its seal section extends upwardly to delivery connection liquid port place, the plunger upper and lower part chamfering of all strike-ofing, 0-60 ° of its chamfer angle.
During oil well pump work, plunger is up, traveling valve cuts out, standing valve is opened, liquid is through duplex fitting liquid feeding channel radially in the well, standing valve flows into pump chamber, simultaneously, the sand block guiding valve is opened under liquid flow impact, the plunger extract, in this process, the effect of plunger can scrape near the sand grains the pump barrel inwall in the plunger cavity effectively owing to strike-off, and has eliminated between plunger and the pump barrel because the rigid extrusion friction power that the compaction of sand grains forms, and effectively prevent sand card plunger, because plunger only moves under the minimum friction state, also can prolong the working life of plunger to greatest extent simultaneously, prolong the manufacture cycle of oil well.During down stroke, plunger is descending, standing valve cuts out, and traveling valve is opened, and the sand block slide valve seat is on the slide valve seat joint, stopped that sand grains falls into pump barrel, by plunger fluid joint liquid port place drain, because the souring of liquid stream, rinse well by near a spot of sand grains that energy will lodge in the plunger liquid port by traveling valve for liquid in the pump chamber of plunger below, work in best cleaning ambient so that when next upstroke, guarantee plunger, prevent sand card plunger.In addition, since sand block guiding valve in the utility model, the unique design of annular sand setting passage, no matter at normal pumping of pump or stop pumping state, because of the sand block effect of sand block guiding valve, the sand grains of whereabouts can only sink under the pump in the tail pipe by annular sand setting passage in the pump, plays the effect that prevents sand buried column plug.
Description of drawings of the present utility model is as follows:
Fig. 1 looks sectional view for master of the present utility model
Fig. 2 looks sectional view A-A sectional drawing for master of the present utility model
The utility model is further described below in conjunction with embodiment:
As shown in Figure 1: the plunger type of strike-ofing sand-proof oil-well pump is that pump barrel 7 is connected with duplex fitting 11 by standing valve 13, the pump barrel upper end is connected with slide valve seat joint 20, the slide valve seat joint compresses pump barrel centralizer body 5, the assurance pump barrel is placed in the middle, urceolus 6 is directly received in the duplex fitting, duplex fitting has radially liquid feeding channel 10 and axially sand setting passage 12, the urceolus upper end connects upper connection 1, the thrust spring 2 that is compressed by crimp head 3 is housed in the upper connection, play and stop that sand block guiding valve 4 breaks away from the effect of oil well pump, form an annular sand setting passage 8 between urceolus and the pump barrel, provide sand grains to fall into the passage of tail pipe; 18 of the plungers of strike-ofing are assembled by afterbody joint 14, traveling valve 15, the valve bonnet 16 that moves about, plunger body 17, delivery connection 19, the plunger upper and lower part of strike-ofing is 60 ° of chamferings structures of strike-ofing, the plunger seal section extends upwardly to delivery connection liquid port place, the valve bonnet 9 that moves about is streamlined structure, to reduce hydraulic loss; The sand block guiding valve is placed on the connecting rod 21, links to each other, insert pump barrel with the plunger of strike-ofing.
The utility model compared with prior art its advantage has: simple in structure, and job execution Easy to operate, cost is low, and liquid stream is little by the hydraulic loss of plunger and standing valve, favourable Descending in plunger, have simultaneously the characteristic of sands-proof check plunger, sand control buried column plug concurrently, can be maximum The prolongation oil pump plunger piston of limit, the service life of pump barrel.
The utility model can be widely used in height and contain sand drain, also can be applied to the part viscous crude, The gassiness sand output well.
