Description
Technical field
The utility model relates to the technical field of oil field operation, relates in particular to a kind of oil well pump.
Background technique
Often taking place to drop on the standing valve in the pump process down as dirts such as broken cotton yarn, broken rubber, raw meal belts; Under take out in the bar process, take out the dirt on the bar and take out down and take out knock-off joint in the bar process and take out the bar centralizer and scrape dirt, the iron filings of tube wall under scraping and also drop on the standing valve, cause the card blow-by of standing valve ball or block not fluid of standing valve.In oil pumping process, dirt on the tubing string inwall, iron filings are pumped by sucker rod and scrape, the fragment that oil pumping rod centering device is ground away, the dirts such as sand that the stratum goes out all drop in the pump barrel, cause holddown or cause the oil well pump wearing and tearing, make the oil well pump premature failure, make that pump detection and workover is frequent, cost of production improves.For this reason, develop anti-dirty antiscale sand control anti-sticking four anti-deep-well oil pumps.
The model utility content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of four anti-deep-well oil pumps with anti-dirty antiscale anti-sticking sand control to be provided.
The purpose of this utility model is achieved in that a kind of four anti-deep-well oil pumps, comprise pump barrel, plunger, last travelling valve, following travelling valve and standing valve, described plunger is set in the pump barrel, the lower end thread connecting plunger joint of plunger, described go up travelling valve comprise valve cover, first steel ball, on move about valve seat and last valve joint, the lower end thread connecting plunger of last valve joint; Described down travelling valve comprises down valve cover, second steel ball, move about valve seat and following valve joint down, the upper end thread connecting plunger joint of following valve cover; Described standing valve comprises standing valve cover, the 3rd steel ball, standing valve seat and standing valve joint, described oil well pump also comprises upper connection, the lower end of upper connection first outer tube that is threaded, the lower end of first outer tube connects transition joint by first box cupling, the lower end of transition joint connects second outer tube by second box cupling, and the lower end of second outer tube connects lower contact by the 3rd box cupling; Described pump barrel is arranged in the upper connection and first outer tube, be threaded righting strip and scrape ring joint of the upper end of described pump barrel, scrape ring joint and be arranged on the upper end of righting strip, the upper end of the scraping ring joint guide sub that is threaded is at guide sub and scrape scraping ring is set between the ring joint; The lower end of described pump barrel connects a connecting tube by the pump barrel joint, and the lower end outside thread of connecting tube connects described transition joint; Described standing valve is arranged in second outer tube, the upper end of the described standing valve cover oil inlet pipe that is threaded, and the upper end of the oil inlet pipe oil-feed cap that is threaded, the lower end of described standing valve joint is threaded in the upper end of lower contact.
In following pump process, sink under the dirt that comes off on dirt in the tubing string such as broken cotton yarn, broken rubber, raw meal belt etc., the tube wall, the iron filings in the annular space that constitutes between the outer tube of four anti-standing valves and oil inlet pipe; In like manner, in the oil pumping process, the sand that the stratum goes out enters pump barrel through oil inlet pipe, oil-feed cap, and simultaneously, the part sand grains also sinks to down under action of gravity in the outer tube and the annular space between oil inlet pipe of four anti-standing valves, can not drop in the standing valve.Therefore, can not fasten valve ball or stifled standing valve causes the standing valve blow-by or blocks problem.In oil pumping process, crude oil enters pump barrel through standing valve, oil inlet pipe, oil-feed cap, and two travelling valves enter in the tubing string to ground flow about plunger; Standing valve is opened oil-feed during upstroke, and plunger is up, and travelling valve is closed and carried oil; During down stroke, standing valve is closed, and plunger is descending, and travelling valve is opened oil-feed.No matter where long-plunger is in, and always has one section plunger to expose to the pump barrel top, and therefore, dirts such as the part sand grains that the fragment that the dirt on the tubing string inwall, iron filings and oil pumping rod centering device are ground away, stratum go out can not drop in the pump barrel; Simultaneously, the scraping ring on pump barrel top also works the effect of strike-ofing, and prevents that sand grains from entering the gap between pump barrel and the plunger; In the outer tube that dirts such as the part sand grains that fragment that the dirt on the tubing string inwall, iron filings and oil pumping rod centering device are ground away and stratum go out all sink to four anti-pump barrels down and the annular space of pump barrel assembly formation, prevent that dirt from causing holddown above entering the gap between plunger and the pump barrel or being deposited in pump barrel, simultaneously, alleviate the wearing and tearing between pump barrel and the plunger, prolong the working life of pump.
Characteristics:
1. anti-dirty, antiscale, anti-sticking, sand control.
In following pump and oil pumping process, can prevent effectively that the fragment that dirt, iron filings and the oil pumping rod centering device on dirt, the tube wall ground away in the tubing string, the dirts such as sand that the stratum goes out from entering fastening valve or blocking standing valve or holddown of causing in standing valve and the pump barrel; Prevent that sand grains from entering the seal clearance between plunger and the pump barrel, reduce wearing and tearing pump barrel and plunger.
2. the life-span is long.
In oil pumping process, can prevent effectively that sand grains from entering the seal clearance between plunger and the pump barrel, reduce wearing and tearing to pump barrel and plunger, prolong the working life of pump.
3. alleviate rod and tube partial-wear.
Because outlet valve is exposed on the pump barrel all the time on this pump, so fuel-displaced resistance greatly reduces than conventional pumps, is specially adapted to the viscous crude sand output well.Simultaneously, roofbolt is not flexible when descending, and rod tube mill phenomenon is eased.
4. use easy to maintenance.
Do not have specific (special) requirements in this pump using process, all valves and valve bonnet all adopt standard piece, easy accessibility.
