Abstract
The utility model relates to a kind of sand-proof oil-well pump for oilfield production operation, particularly to one strong draining heavy ball reaming sand-proof oil-well pump, by pump barrel box cupling (1), sand-proof plunger assembly (2), pump barrel (3), forcing bleeder assembly (4), heavy ball reaming standing valve assembly (5) to form, pump barrel box cupling (1) is threaded connection with pump barrel (3)；Pump barrel (3) is threaded connection with forcing bleeder assembly (4)；Bleeder assembly (4) is forced to be threaded connection with heavy ball reaming standing valve assembly (5)；Threadeded by sucker rod between sand-proof plunger assembly (2) and the sucker rod on the upside of it.The utility model have employed spiral sand-proof plunger, effectively can take to ground sand production with oil stream；In bottom owing to using heavy ball reaming standing valve assembly, increase the area of passage in oil recovery process, it is ensured that bottom valve quick closedown is to improve pump efficiency.
Description
Technical field
The utility model relates to a kind of sand-proof oil-well pump for oilfield production operation, particularly to the strong draining of one
Heavy ball reaming sand-proof oil-well pump.
Background technology
At present, the oil well pump species of oil producing operation onsite application is more, is respectively arranged with feature, but is respectively arranged with deficiency.This product master
Will be for the more situation of sand production, it is preferred that emphasis is will shake out as far as possible and take to ground, and prevent sand card sand from burying oil well pump.
Content of the invention
For the more situation of sand production, the utility model provides a kind of strong draining heavy ball reaming sand-proof oil-well pump, energy
Enough shaking out is taken to ground, prevents sand card sand from burying oil well pump.
The technical solution of the utility model is as follows:
A kind of strong draining heavy ball reaming sand-proof oil-well pump, by pump barrel box cupling (1), spiral sand control assembly for plunger (2), pump barrel
(3), forcing bleeder assembly (4), heavy ball reaming standing valve assembly (5) composition, pump barrel box cupling (1) and pump barrel (3) pass through spiral shell
Line connects；Pump barrel (3) is threaded connection with forcing bleeder assembly (4)；Bleeder assembly (4) is forced to be fixed with heavy ball reaming
Valve assembly (5) is threaded connection；Between sand-proof plunger assembly (2) and the sucker rod on the upside of it by sucker rod screw thread even
Connecing, the top of sand-proof plunger assembly (2) is provided with device of strike-ofing (21), and the bottom of sand-proof plunger assembly (2) is provided with down device of strike-ofing
(22)。
Technical characteristics of the present utility model is:
1st, using novel sand-proof plunger, being characterized on sand-proof plunger having device of strike-ofing up and down, the effect of device of above strike-ofing is
Silt particle above plunger is scraped converge into extraordinary plunger connector and oil stream and rotate and prevent from reentering pump barrel；Under strike-off the work of device
Be the silt particle below plunger is scraped and imports in liquid flow extraordinary plunger connector enter plunger liquid is discharged to ground.
2nd, a grade is strengthened in standing valve hole, standing valve cover is processed into streamlined working and reduces liquid exactly
Entering pump resistance, purpose valve ball being become heavy ball is just to speed up valve closing velocity, improves pump efficiency.
3rd, in the general structure of pump, add pressure bleeder be contained in the middle of pump barrel and standing valve cover, in workover treatment
When, after tripping out plunger, the draining copper core forcing bleeder is cut off by lower gravity rod, opens bleeder draining, and ground can be prevented dirty
Dye.
Brief description
Fig. 1 is structure diagram of the present utility model.
Wherein 1-pump barrel box cupling, 2-spiral sand control assembly for plunger, 3--pump barrel, 4--forces bleeder assembly, and 5--heavy ball is expanded
Hole standing valve assembly, device that 21-strike-offs, device of strike-ofing under 22-.
Detailed description of the invention
The utility model is achieved in that whole oil well pump uses modular construction, from top to bottom by pump barrel box cupling the 1st,
The 3rd, spiral sand control assembly for plunger the 2nd, pump barrel forces bleeder assembly the 4th, heavy ball reaming standing valve assembly 5 to constitute.Its general structure
And assembling process is as follows: be connected pump barrel box cupling 1 with pump barrel 3 upper end, pump barrel 3 lower end is connected with forcing bleeder assembly 4 upper end,
Bleeder assembly 4 lower end is forced to be connected with reaming standing valve assembly 5.Spiral sand control assembly for plunger 2 and the sucker rod on the upside of it
Between by sucker rod threaded, the top of sand-proof plunger assembly 2 is provided with device 21 of strike-ofing, the bottom of sand-proof plunger assembly 2
It is provided with down device 22 of strike-ofing.
The utility model in oil recovery process owing to have employed spiral sand-proof plunger, can effectively by sand production with oil stream
Take to ground；In bottom due to employing reaming standing valve assembly, and use heavy ball, so on the one hand increase oil recovery process
In area of passage, on the other hand bottom valve quick closedown can be ensured to improve pump efficiency when pumping down stroke；At this oil well pump
Structure increases and forces bleeder assembly, can propose, during well head, all liq in oil pipe is excreted to well at this oil well pump
In, thus greatly reduce lifting load, and prevent from polluting ground.
