The beneficial effect of the utility model is: on the one hand, through the stratum is aspirated by force, effectively remove formation blockage, can reach the purpose that activates stratum, mediation oil flow channel; On the other hand; Utilize the energy that the oil pipe wriggling produces in the oil pumping process, send jarring, effectively import shock wave into oil reservoir through bell vibrating plate group through acoustic wave source; Excitation crude oil flows into pit shaft; And, make the stratum be difficult for forming new obstruction to the effect that the stratum is played suction all the time, impacted, reach synergy and the purpose that improves crude output.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
Among the figure: 1. top connection; 2. go up valve; 3. go up the envelope group; 4. adjustable ring; 5. seal tube down; 6. lower contact; 7. acoustic wave source; 8.42 valve under ° opening angle; 9. centralizer; 10. bell vibrating plate group; 11. screen casing.
The specific embodiment
Below in conjunction with specific embodiment the utility model is further specified.
Accompanying drawing can be used as the structural representation of the utility model specific embodiment.
The top of top connection (1) is the D73mm tubing thread, is connected bottom with oil well pump, and last valve (2) plays the oil flow direction and goes up folk prescription to the effect of passing through, and when vibrations de-plugging synergy oil extraction device moved upward, last valve (2) was closed.Last envelope group (3), following envelope tube (5) are worked in coordination, and play the effect of Seal Oil pipe-in-pipe annular space.Last envelope group (3) is metallic seal, and following envelope tube (5) is rubber seal.
When vibrations de-plugging synergy oil extraction device moved upward, last envelope group (3) sealing casing tube annular space was because head of liquid; Last envelope group (3) presses down adjustable ring (4); Adjustable ring (4) is depressed envelope tube (5) again down, and following envelope tube (5) pressurized rises greatly, with the more step sealing of oil pipe, sleeve pipe annular space; Just formed the stratum has been aspirated by force, extracted the formation blockage thing out; When vibrations de-plugging synergy oil extraction device moves downward; Last envelope group (3) no longer presses down adjustable ring (4) and seals tube (5) down; Following envelope tube (5) not pressurized is got back to nature; Last envelope group (3) is only leaned in the sealing of oil pipe, sleeve pipe annular space, like this to stratum reverse impact power just less than suction force, do not make the obstruction of extraction push back the stratum again from the stratum.
Adjustable ring (4) can be according to the degree of depth in the vibrations de-plugging synergy oil extraction device lower going-into-well; The dynamics that last envelope group (3) is depressed into down envelope tube (5) is made adjusting; That is: according to different depth of settings, under the head of liquid condition of different, adjust down the sealing between envelope tube (5) and sleeve pipe.Following envelope tube (5) can also play the effect of setting upright envelope group (3) simultaneously, prevents to cause envelope group (3) that sleeve pipe is produced eccentric wear, the damage sleeve pipe.
There is a piston type expansion coupling acoustic wave source (7) inside, and the free travel of 210mm is arranged, and centralizer (9) is made up of three wiper blocks, and inner spring supports expansion, closely contacts with internal surface of sleeve pipe and produces friction.When vibrations de-plugging synergy oil extraction device moves upward; Acoustic wave source (7) piston expansion coupling is pulled out fully; When moving downward,, just caused the piston expansion coupling of acoustic wave source (7) to be retracted to top dead-centre because centralizer (9) closely contacts with sleeve pipe; Produce bump thus, pass to bell vibrating plate group (10) shock wave takes place; When vibrations de-plugging synergy oil extraction device secondary moved upward, same because centralizer (9) contacts with the tight of sleeve pipe, and the piston expansion coupling of acoustic wave source (7) is pulled out to bottom dead centre, the generation secondary impact was passed to bell vibrating plate group (10) and is produced shock wave.Acoustic wave source (7) comes to this and clashes into up and down, produces shock wave excitation oil reservoir.
Valve (8) is an opening angle dish valve under 42 ° of opening angles, when vibrations de-plugging synergy oil extraction device moves upward, opens, and closes when moving downwards, plays the effect of the close inside center pipe of envelope, forms the stratum reverse impact.When beginning strong suction end in 2-3 hour, after the oil well operate as normal, valve (8) is opened under 42 ° of opening angles, and oil stream passes through central tube smoothly.
Bell vibrating plate group (10) outside is bell housing; Inside is multi-disc vibrating plate group; After acoustic wave source (7) sent bump, bell vibrating plate group (10) produced shock wave, under the protection of bell housing; Make shock wave effectively import the stratum into, flow into the purpose that pit shaft improves oil well pump efficient to reach the excitation in-place oil.
