Abstract
The utility model relates to a sand control oil pump of an oil field, comprising a pump cylinder, a plunger assembly, a suspension joint, a valve ball in a valve cover, a valve base, a connector, a cyclone and an oil inlet joint. In the upstroke, when pumps oil and absorbs liquid, the mixture in the muffle changes the liquid flow into cyclone state via a helical flow channel at the lower of the bottom valve, to clean the sand and foreign materials on the surfaces of the valve ball suspended in the flow liquid and in the valve cover via cyclone, to keep the surface of the valve ball and around flow channels clean all the time, and in the down stroke, when discharges liquid, the suspended dirt is discharged from the pump cylinder with the liquid and is fed into the oil pipe, thereby completing cyclone self cleaning lifting liquid absorption and liquid discharge, to effectively reduce sand block and abrasion, prolong the pump check period and reduce production cost. The utility model is suitable for the oil region whose ground layer is easy to form sand and wax, block pumping well, high water content production pumping well and the pumping well of easily scaled formation water.
Description
Technical field
The utility model belongs to the sand-proof oil-well pump in oil field, relate in particular to a kind of can finish swirling flow from the swirling flow of washing lifting imbibition, discharge opeing working procedure from washing big runner sand-proof oil-well pump.
Background technique
Current, because common sand-proof oil-well pump is in upstroke oil recovery imbibition process, when the mixing material in the sleeve pipe passes through bottom valve, be suspended in sand grains in the liquid stream and foreign matter accumulate in easily the valve ball surface and around in the runner, the wearing and tearing of aggravation valve ball, sand card, sand milling phenomenon easily taking place, make the oil well pump premature failure, shortens the working life of oil well pump.Cause that the oil well operation is frequent, cost of production improves.The utility model swirling flow is when washing big runner sand-proof oil-well pump in upstroke oil pumping imbibition, mixing material is by bottom valve bottom spiral flow channel in the sleeve pipe, make liquid stream become the swirling flow state, carry out swirling flow and clean being suspended in valve ball surface in the liquid stream and the sand grains in your the cover runner of valve and foreign matter, all the time clean in the runner around assurance valve ball surface reaches and do not accumulate foul, in oil well pump down stroke discharge opeing process, the suspension foul is discharged pump barrel with liquid enter the top oil pipe, finish swirling flow from washing lifting imbibition, discharge opeing working procedure.
The model utility content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and provides a kind of swirling flow from washing big runner sand-proof oil-well pump.
The utility model for achieving the above object, by the following technical solutions: swirling flow comprises from washing big runner sand-proof oil-well pump: pump barrel, plunger piston assembly, suspension joint, place valve ball, valve seat, connecting head, swirler, fuel inlet fitting in the valve bonnet.It is characterized in that: swirler directly is connected the standing valve bottom by joint.The utility model is when upstroke oil pumping imbibition, mixing material in the sleeve pipe is by bottom valve bottom spiral flow channel, making the liquid rheology is the swirling flow state, enter in the process of pump barrel at rotation liquid stream jack-up valve ball, carry out swirling flow and clean being suspended in valve ball surface in the liquid stream and the sand grains in your the cover runner of valve and foreign matter, all the time clean in the runner around assurance valve ball surface reaches and do not accumulate foul, rotating liquid is flowed through behind the valve ball, because of valve ball chamber upper runner latus rectum big, reduced the liquid in rotation energy loss significantly, kept liquid swirling flow state to greatest extent, the foul rotating lifting that liquid will be suspended in the liquid can not be guaranteed to fall after rise, in oil well pump down stroke discharge opeing process, the suspension foul is discharged pump barrel with liquid enter the top oil pipe, finish swirling flow from washing the lifting imbibition, the discharge opeing working procedure.Thereby reduce sand card, sand milling phenomenon effectively, prolonged pump detection period greatly, reduce production costs.
Description of drawings
Fig. 1 is the spiral organ structural representation;
Fig. 2 is the structural representation of single-head screw among Fig. 1;
Fig. 3 is that the utility model swirling flow is from the structural representation of washing big runner sand-proof oil-well pump.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment:
As shown in Figure 3, swirling flow comprises that from washing big runner sand-proof oil-well pump pump barrel 10, plunger piston assembly 5, suspension joint 1 reach and be made up of valve bonnet 11, endosphere 12, valve seat 13, swirler 16,17 of bottom box cuplings (oil-feed pipe close).The swirler 16 outer tube 15 usefulness bottom box cuplings 17 of packing into tighten, and joint 14 are tightened again.At this moment the swirling flow assembly installs, and swirler is connected with the oil well pump assembly to tighten at last, just can bring in.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
Claims (2)
1, a kind of swirling flow comprises pump barrel, plunger piston assembly, suspension joint, places valve ball, valve seat, connecting head, swirler, fuel inlet fitting in the valve bonnet from washing big runner sand-proof oil-well pump.It is characterized in that: swirler directly is connected the standing valve bottom by joint.
2, swirling flow according to claim 1 is from washing big runner sand-proof oil-well pump, and it is characterized in that: the spiral chute quantity of single-head screw is the 8-12 bar in the described swirler.
