Abstract
The invention relates to the technical field of chemical combination flooding, water flooding or polymer flooding oil recovery in oilfields, particularly a chemical combination flooding scale-deposition antiscale oil well pump. The invention provides a chemical combination flooding scale-deposition antiscale oil well pump capable of effectively preventing a stuck pump failure. The chemical combination flooding scale-deposition antiscale oil well pump is composed of a pump barrel 1, a pumping rod short joint 2, an upper oil outlet joint 3, an alloy plunger 4, a scale scraping assembly 5, a scale scraping ring 6, a traveling valve cover 7, a traveling valve ball 8, a traveling valve seat and a traveling valve plug 10, wherein the upper part of the outer wall of the upper oil outlet joint 3 is connected with the lower part of the alloy plunger 4 through screw threads; and the lower part of the outer wall of the upper oil outlet joint 3 is connected with the scale scraping assembly 5 through screw threads. The chemical combination flooding scale-deposition antiscale oil well pump is suitable for recovery well elevation of water flooding, polymer flooding and chemical combination flooding. The invention can maximally prolong the pump check period, effectively prevent the stuck pump phenomenon, enhance the pump efficiency, lower the production cost and the like.
Description
Technical field: the present invention relates to oilfield chemistry combination flooding, water drive or polymer flooding oil-extraction technical field, especially a kind of chemical combined flooding sinks dirty formula anti-scaling oil-well pump.
Background technique: at present, conventional integeral tube pumping pump is made up of last delivery connection, last travelling valve system, plunger body and following travelling valve system.Wherein go up between delivery connection and the pump barrel inwall and have wedge shape space, when oil well pump was worked, dirt in the oil pipe or sand grains can be fallen in the gap of pump barrel and plunger through wedge shape space, cause holddown.Outer plunger surface and pump barrel internal surface also fouling can occur on the other hand, cause the holddown fault.
The present invention is through moving down delivery connection on the plunger; Removed the wedge shape space between the delivery connection and pump barrel inwall on the plunger; Adopt the scraper device of ultra-high molecule material simultaneously, significantly reduced the fouling of plunger body and pump barrel internal surface, thereby reduced the generation of holddown fault.
Summary of the invention: the purpose of this invention is to provide a kind of sand grains of avoiding and got between plunger and the pump barrel, and effectively prevented the heavy dirty formula anti-scaling oil-well pump of chemical combined flooding that the holddown fault takes place.
The technological scheme that the present invention adopted is: it by pump barrel, sucker rod short circuit, go up delivery connection, alloy plunger, scrape dirty assembly, wiper ring, the valve bonnet that moves about, the valve ball that moves about, move about valve seat and traveling valve plug form; Wherein the sucker rod short circuit is through delivery connection in the screwed connection; Last delivery connection outer wall top is connected with alloy plunger bottom through screw thread, the interior chamfering structure of alloy plunger upper part employing, last delivery connection outer wall bottom through screw thread with scrape dirty assembly and be connected; Scrape in the dirty assembly outer wall groove one group of wiper ring is housed; Scrape dirty assembly bottom and be connected with the valve bonnet that moves about through screw thread, the move about valve ball and the valve seat that moves about are housed in the valve bonnet that moves about, the valve bonnet bottom of moving about is connected with the traveling valve plug through screw thread.
Wiper ring is the ultra-high molecule material.Scrape the dirty assembly and the outer spraying of the valve bonnet antiscale coating of moving about.
Compared with present technology the present invention has following advantage:
1), the present invention moves down direct connection and scrapes dirty assembly and travelling valve system through going up delivery connection; Removed the wedge-shaped structure of conventional integeral tube pumping pump plunger and pump barrel; When this anti-scaling oil-well pump moved upward, it is inner that dirt or sand grains can fall into the alloy plunger, and flow can be washed away alloy plunger inside when moving downward; Dirt and sand grains can be taken pump barrel out of with flow, effectively prevent the generation of dirt card.
2), bottom of the present invention installed by what the ultra-high molecule material was formed and scraped dirty system, when oil well pump is scraped dirt, the holddown of having avoided plunger body outer wall and pump barrel encrustation to cause; Prolong pump detection period to greatest extent, improved pump efficiency simultaneously, reduced cost of production.
Description of drawings: Fig. 1 is a structural representation of the present invention;
Among the figure: the 1-pump barrel, 2-sucker rod short circuit, the last delivery connection of 3-, 4-alloy plunger, 5-scrapes dirty assembly, 6-wiper ring, the 7-valve bonnet that moves about, the 8-valve ball that moves about, the 9-valve seat that moves about, the 10-valve bonnet that moves about.
Embodiment: the present invention is described further below in conjunction with embodiment: it by pump barrel 1, sucker rod short circuit 2, go up delivery connection 3, alloy plunger 4, scrape dirty assembly 5, wiper ring 6, the valve bonnet 7 that moves about, the valve ball 8 that moves about, move about valve seat 9 and traveling valve plug 10 form; Wherein sucker rod short circuit 2 is through delivery connection in the screwed connection 3; Last delivery connection 3 outer wall tops are connected with alloy plunger 4 bottoms through screw thread; Chamfering structure in adopt on alloy plunger 4 tops; Last delivery connection 3 outer wall bottoms through screw thread with scrape dirty assembly 5 and be connected, scrape in the dirty assembly 5 outer wall grooves one group of wiper ring 6 be housed, scrape dirty assembly 5 bottoms and be connected with the valve bonnet 7 that moves about through screw thread; Move about be equipped with in the valve bonnet 7 move about valve ball 8 with move about valve seat 9, valve bonnet 7 bottoms of moving about are connected with traveling valve plug 10 through screw thread.
Wiper ring 6 is the ultra-high molecule material.Scrape the dirty assembly 5 and the valve bonnet 7 outer spraying antiscale coatings of moving about.
During The field, when the oil well operation, oil pipe is connected pump barrel 1, down to the shaft bottom; Then sucker rod is connected with sucker rod short circuit 2, in pump barrel 1, accomplishes the site operation operation down.During work, this installs under the drive of sucker rod, does pumping; During upstroke, alloy plunger 4 is scraped dirt with wiper ring 6, and sand grains or dirt grain fall into alloy plunger 4 inside; Flow can be washed away alloy plunger 4 inside during down stroke, and dirt and sand grains can be taken pump barrel 1 out of with flow.
