Abstract
The utility model relates to a screw pump is enlarged in pit and is controlled reverse rotator, its characterized in that: it constitutes to take place room, vortex generator, ball seat, shock steel ball and lower clutch by the vortex, the vortex generator set up and to take place indoorly at the vortex, vortex generator surface is equipped with the spiral passageway, the vortex takes place room one side to be connected with the lower clutch and to fix, the ball seat setting junction of room and lower clutch takes place at the vortex inside, vibrate the steel ball setting between vortex generator and ball seat, be equipped with evenly distributed's slot on the inner wall that ball seat and shock steel ball are connected, this screw pump is enlarged in pit and is controlled reverse rotator transfers to downhole control reversal with the direction changing design of ground control, and production is safe and reliable more, has designed longer vortex and has taken place room and vortex generator, can effectively increase the screw pump inlet pressure, total and increased screw pump efficiency, has improved the product fluid power of screw pump well to do all can, has reduced the safe risk of screw pump well, can satisfy the oil recovery well betterly and lift needs.
Description
Technical field
This utility model relates to oil field development technical field, particularly relates to potentiation control inversion set under a kind of screw bolt well,
Belong to screw pump oil production well down-hole corollary apparatus.
Background technology
Screw pump as a kind of mechanical oil recovery equipment in oil field, has very at viscous crude, the aspect such as exploitation containing sand, high-gas-contained well
Good adaptability, and there is the features such as little, easy for installation, the low power consuming of volume.But during field use, find screw pump
There are two deficiencies, one is that jacking capacity is poor, causes submergence high, affects the balanced flood of block, limits liquid-producing capacity；Two are
Poor safety performance, after screw bolt well is shut down, the pressure reduction that the highly pressurised liquid in oil pipe and external transport pipeline is formed with well liquid in sleeve pipe
Under effect, screw pump can become hydraulic pressure screw motor, makes the roofbolt of rotor and connection quickly invert, ultimately result in polished rod twist off send out
Make trouble former.
Summary of the invention
In order to solve deficiency of the prior art, the purpose of this utility model is to provide potentiation control under a kind of screw bolt well
Inversion set, improves the liquid-producing capacity of screw bolt well, reduces the security risk of screw bolt well.
This utility model solves its technical problem and be the technical scheme is that
Potentiation control inversion set under a kind of screw bolt well, it is characterised in that: by vortex generation chamber, vortex generator, ball seat,
Concussion steel ball and lower contact are constituted, and described vortex generator is arranged in vortex generation chamber, and vortex generator surface is provided with spiral shell
Rotation shape passage, vortex generation chamber side is connected fixing with lower contact, and described ball seat is arranged on vortex generation chamber and lower contact
Inside junction, concussion steel ball is arranged between vortex generator and ball seat, and the inwall that ball seat is connected with concussion steel ball is provided with
Equally distributed groove.
The beneficial effects of the utility model are: under screw bolt well, the design that ground controls reversion is turned by potentiation control inversion set
Moving on to down-hole and control reversion, producing can be more safe and reliable, devises longer vortex generation chamber and vortex generator, it is possible to effectively
Increase screw pump inlet pressure, always add screw pump efficiency, improve the liquid-producing capacity of screw bolt well, reduce screw pump
The security risk of well, it is possible to preferably meet producing well lifting needs.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
In figure: 1 vortex generation chamber, 2 vortex generators, 3 ball seats, 4 concussion steel balls, 5 lower contacts, 6 grooves, 7 spiral types are led to
Road.
Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model being described below, those skilled in the art can be by this
Content disclosed by description understands other advantages of the present utility model and effect easily.
As shown in Figure 1: potentiation control inversion set under a kind of screw bolt well, by vortex generation chamber 1, vortex generator 2, ball seat
3, concussion steel ball 4 and lower contact 5 are constituted, and described vortex generator 2 is arranged in vortex generation chamber 1, vortex generator 2 surface
Being provided with spirality channel 7, vortex generation chamber 1 side is connected fixing with lower contact 5, and described ball seat 3 is arranged on vortex generation chamber 1
Inside the junction of lower contact 5, concussion steel ball 4 is arranged between vortex generator 2 and ball seat 3, ball seat 3 and concussion steel ball 4
The inwall connected is provided with equally distributed four grooves 6.
Under above-mentioned a kind of screw bolt well, potentiation control inversion set is arranged on screw pump lower end, its sky inversion structures mainly by
Concussion steel ball 4 and ball seat 3 are constituted, and ball seat 3 inwall has four grooves 6, can control pipeline road and ground by groove 6
The high speed reverse rotation that in pipeline, flow liquid backflow causes, reduces bottom surface risk, rotor can be allowed again to enter stator smoothly, and its potentiation is tied
Structure is mainly completed by vortex generation chamber 1 and vortex generator 2, makes entrance crude oil produce high-speed eddy motion, crude stream kinetic energy
Power improves more than 10 times, and under turbulent state, oil flow pressure increases makes profit be sufficiently mixed, and also makes original with cancellated
Paraffin molecule is fully dispersed to profit, and the fine crystalline that paraffin molecule is formed is difficult to combine, and paraffin separates out and obtains
Suppression.
Under this screw bolt well after the application of potentiation control inversion set, both can improve the liquid-producing capacity of screw bolt well, again may be used
To reduce the security risk of screw bolt well, it is possible to preferably meet producing well lifting needs.
The foregoing is only preferred embodiments of the present utility model, as long as realizing this utility model with essentially identical means
Purpose technical scheme, within broadly falling into protection domain of the present utility model.
