Abstract
The utility model discloses a whirl sand-scraping oil-well pump which is applied to oil industry. The utility model comprised an oil-well pump barrel system, an oil-well pump plunger system, a group valve capable of wandering up and down and standing valve assembly. The lower joint of a plunger is provided with a sand-scraping port, the inner surface of a pump barrel has a sand-scraping groove, and the upper joint is provided with a fluid discharge port. Compared with a common oil-well pump, the utility model can effectively prevent a plunger being stuck by sand and a plunger pump barrel being ground by sand, greatly decelerate the abrasion between a plunger and a pump barrel, improve the high pumping efficiency productive periods of an oil-well pump and prolong the production periods of a sand well. Because the cost of the utility model is close to the common oil-well pump, the use, the operation, the maintenance, etc. are the same with the common oil-well pump. Therefore, the utility model can replace various common pumps to be used in various oil wells.
Description
Technical field
A kind of oil well pump, particularly eddy flow that the utility model the belongs to petroleum industry oil well pump of strike-ofing is applicable to all kinds of oil wells.
Technical background
Oil field development is to middle back high water-cut stage, the sand production problem is serious day by day, used conventional oil well pump is not optimized design because of containing the sand problem at well liquid, exist the problem of sand milling pump barrel, plunger, cause the wearing and tearing early failue of oil well pump because of sand grains, oil well repair free period is shortened greatly, and its direct result is exactly to cause the rising of operation cost, and the oil well Master Cost increases.Be applied to also some new technology appearance of oil well pump on the sand well, as: pump barrel has the combined type oil well pump of anti-sand launder, number of patent application: 94203364.7, the combined type oil well pump that this model utility is made up of pump barrel cylinder sleeve and plunger, be characterized on the endoporus two ends of pump barrel cylinder sleeve a concave station being arranged respectively, pump barrel assembling back forms a plurality of equally distributed anti-sand launders in pump barrel, plunger is the slotless plunger, and there is one section cylndrical surface that is slightly less than plunger diameter at two ends.Form an annular space between cylndrical surface and the pump barrel, can play the effect of strike-ofing, the anti-sand launder on the pump barrel can deposit at any time and flow out sand grains, reaches effectively to prevent the direct wearing and tearing of sand grains to oil well pump cylinder sleeve and plunger.This model utility is only scraped sand launder in the design of oil well pump lining junction point, what be not implemented in whole tube pump internal surface scrapes the sand launder design, in addition, do not realize the eddy flow sand washing design of the strike-off design and the plunger upper connection of plunger, therefore, bigger narrow limitation is arranged in the use, can not replace conventional pumps and use.
Summary of the invention
The purpose of this utility model provides the eddy flow oil well pump of strike-ofing, on sand well, use sand card, sand milling oil pump plunger piston, the pump barrel problem that exists at conventional oil well pump, overcome defective above-mentioned in the prior art, improve the high pump efficiency campaign of oil well pump, prolong the manufacture cycle of sand well.
The purpose of this utility model reaches like this: the eddy flow oil well pump of strike-ofing, have oil well pump pump barrel system, oil pump plunger piston system, wander up and down valve group and standing valve assembly, the plunger lower contact is provided with the mouth of strike-ofing, and the pump barrel internal surface is provided with scrapes sand launder, and upper connection is provided with liquid port.
The utility model is by adopting the isometrical dual principle of strike-ofing of strike-ofing the plunger technology and scraping sand launder in the design of pump barrel two ends, cooperate the eddy flow liquid port design that is positioned at the plunger system upper end, reaching dual strike-offs and the effect of eddy flow sand washing, compare with conventional oil well pump, have the sand card plunger that can effectively prevent in the sand well, the generation of sand milling plunger pump barrel phenomenon, slow down the wearing and tearing between plunger and pump barrel greatly, improve the high pump efficiency campaign of oil well pump, prolong the sand well manufacture cycle.The utility model uses operation, maintenance etc. identical with conventional oil well pump because of approaching conventional oil well pump on cost, therefore, can replace various conventional pumps and be used for all kinds of oil wells.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Below in conjunction with embodiment the utility model is done further detailed description: as shown in drawings, pump barrel 2 up and down respectively with upper connection 1, be connected box cupling 3 and connect to form oil well pump pump barrel system.Pump barrel 2 internal surfaces are provided with scrapes sand launder, and this accompanying drawing is illustrated two groups, can be single the group or more groups.These two groups are scraped sand launder is to scrape sand launder 13 and 14, is positioned at the two ends of pump barrel 2 internal surfaces, scrapes sand launder 13 and 14 and can be designed as single, many spiralitys, single, many oblique or single, many horizontal shapes, optional wherein a kind of.Plunger body 5 connects to form the oil pump plunger piston system with plunger upper connection 4, plunger lower contact 6 respectively up and down, and the upper design of plunger upper connection 4 has liquid port 15, and plunger lower contact 6 is provided with the mouth of strike-ofing.The lower travelling valve group that upper travelling valve group that upper traveling valve cage 7, upper travelling valve ball 8, upper travelling valve seat 9 formed and lower travelling valve cover 10, lower travelling valve ball 11, lower travelling valve seat 12 are formed is installed on respectively in the cavity in the plunger body 5.The standing valve assembly is formed in standing valve cover 16, fixed valve ball 17, fixed valve base 18 and lower contact 19, and pump barrel 2 is connected with the standing valve assembly by connecting box cupling 3.Liquid port 15 design is on the top of upper connection 4 with plunger body 5 linkage sections, begins from the upper boss of plunger upper connection 4, and liquid port 15 is multiple tracks skewed slot, multiple tracks straight trough or multiple tracks spiral chute, chooses any one kind of them.With the utility model G.I.H, when plunger body 5 was up, the standing valve assembly was opened, and the upper and lower valve group of moving about is closed, and is the imbibition process; When plunger body 5 is descending, the standing valve assembly is closed, the upper and lower valve group of moving about is opened, be the discharge opeing process, its characteristics be exactly pump barrel 2 internal surfaces apart from two ends designs scrape sand launder 13,14, the intrapore sand grains that can will be stored in 2 of plunger body 5 and pump barrels scrapes in pump barrel 2 design of liquid port 15, realize the eddy flow sand washing effect of down stroke, can solve sand milling plunger, pump barrel problem that conventional oil well pump occurs so effectively.
