Abstract
The utility model relates to a kind of eddy flow Anti-sand oil pump for petroleum industry oil producing operation.It solves thick oil well, the sands-proof check of the low moisture high well oil well pump of production fluid in pumping process, improves sand control ability.Its technological scheme is: sucker rod is connected with plunger by rod collar; The upper and lower valve that moves about is installed in plunger; Tubing coupling is connected with pump barrel, connecting short section, and connecting short section is connected with standing valve valve bonnet, cyclone separator again, and cyclone lower end connects sand sediment pipe and plug; The import of cyclone separator is tangential entry, is arranged on the top of cyclone separator; Oil drainer is arranged on lower end one side of connecting short section.This oil-well pump sand-proof successful, be convenient to maintenance, simple in structure,, shake out height and thick oil well petroleum production low for production fluid.
Description
Technical field
The utility model relates to a kind of oil producing operation for petroleum industry, to thick oil well, the very strong eddy flow Anti-sand oil pump of low, the moisture high well adaptability of production fluid.
Background technique
Along with the increase of oilfield exploitation intensity, sand production problem is more and more serious, and sand card column plug and sand milling plunger become the principal mode that oil well pump lost efficacy.In order to prevent sand card, in oil recovery, use sand screen or screw pump sand control, but the filler opening of sand screen is smaller, the resistance being subject to is large, is not suitable for high containing cured and thick oil well; Screw rod lift of pump is low, discharge capacity is little, is only applicable to shallow-layer, stripper well.So, design a kind of can sands-proof check, the oil well pump that can be applicable to again multiple hole condition is very necessary.
Summary of the invention
The purpose of this utility model is: in order to overcome the deficiencies in the prior art, in conjunction with the feature of cyclone separator and Anti-sand oil pump, provide a kind of eddy flow Anti-sand oil pump.Fluid enters the cyclone separator of oil well pump bottom by tangential entry, sand is rotated and dishes out under centrifugal action, sinks in sand sediment pipe, thereby has improved desanding capacity greatly.
The utility model solves its technical problem by the following technical solutions: a kind of eddy flow Anti-sand oil pump, by sucker rod, tubing coupling, rod collar, plunger upper part oil-release valve cover, traveling valve, pump barrel, connecting short section, oil drainer, standing valve valve bonnet, standing valve, cyclone separator spill pipe joint, the tangential filler opening of cyclone separator, cyclone separator, sand sediment pipe and plug, formed, it is characterized in that: sucker rod lower end with rod collar with being threaded, thread connecting plunger top, rod collar lower end oil-release valve cover; At plunger epimere, install traveling valve, at plunger hypomere, lower travelling valve be installed, upper and lower two traveling valves with plunger all with being threaded; The lower end of tubing coupling is threaded with the upper end of pump barrel, and the lower end of pump barrel is threaded with connecting short section, and connecting short section lower end is threaded with standing valve valve bonnet upper end, and standing valve valve bonnet lower end is connected with cyclone separator spill pipe joint screw thread; The lower end of cyclone separator connects sand sediment pipe, and the termination of sand sediment pipe is threaded with plug; Oil drainer is arranged on bottom in connecting short section, is threaded with connecting short section.
Above-mentioned cyclone separator is arranged on the lower end of standing valve; The tangential filler opening of cyclone separator is installed on cyclone separator; Cyclone separator is positioned at the bottom of oil well pump, makes oil stream first be rotated centrifugal action, has improved the ability of shaking out.
Compared with prior art, its beneficial effect is the utility model: sand controlling result is obvious, is convenient to maintenance, simple in structure, is applicable to that production fluid is low, shake out height and thick oil well petroleum production.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model eddy flow Anti-sand oil pump.
Fig. 2 is the tangential filler opening A-A of Fig. 1 cyclone separator sectional view.
In figure: 1. sucker rod, 2. tubing coupling, 3. rod collar, 4. plunger upper part oil-release valve cover, 5. plunger, 6. upper travelling valve, 7. pump barrel, 8. lower travelling valve, 9. connecting short section, 10. oil drainer, 11. standing valve valve bonnets, 12. standing valves, 13. cyclone separator spill pipe joints, the tangential filler opening of 14. cyclone separator, 15. cyclone separators, 16. sand sediment pipes, 17. plugs.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is illustrated:
According to shown in accompanying drawing, each component being assembled, then go into the well; When instrument arrives predetermined oil recovery position, open aboveground power plant, drive sucker rod to move up and down; When sucker rod 1 moves upward, drive plunger 5 to do upstroke motion, between lower travelling valve 8 and standing valve 12, form negative cavity, the fluid in well enters cyclone separator 15 by the tangential filler opening 14 of cyclone separator; When sucker rod 1 moves downward, drive plunger 5 to do down stroke motion, the oil liquid pressure between lower travelling valve 8 and standing valve 12 increases, and fluid is pushed the spool of lower travelling valve 8 and upper travelling valve 6 open, along the annular space on plunger upper part oil-release valve cover 4 tops, transfer to pump barrel 7 tops; When sucker rod 1 moves upward again, upper travelling valve 6 is closed with lower travelling valve 8, and fluid, along the oil flow channel of tubing coupling 2, is promoted to oil pipe.Fluid in well enters after cyclone separator 15 epicoeles by the tangential filler opening 14 of cyclone separator, because fluid is done rotational flow, make sand be rotated and dish out under the effect of centrifugal force, sink in the sand sediment pipe 16 being connected with cyclone separator 15, thereby reached the object that prevents sand card.During inspection pump, with caber, cut off oil drainer 10 mouthpieces, realize draining.After pump quits work, instrument is proposed from well, take off plug 17, be i.e. pourable sand.
