Background technology
At present, the existing concentric injection well downhole flow regulator for the oil field well seperated layer water injection, the following several point defects of ubiquity:, in the long-term injecting water process, the silt carried in water and impurity are trapped in the annular space of interior water nozzle assembly and main body (1), cause husky card; (2) injection well downhole flow regulator is regulated and to be shut mode, exists moderating force greatly, repeatedly to regulate the defects such as sealing effectiveness is poor; (3) easily cause the tool card wells such as measurement and adjustment instrument device, drift size gauge tool.
The utility model content
The purpose of this utility model is to provide the concentric injection well downhole flow regulator of a kind of bridge-type, has solved sand card, the Ka Jing existed in the prior art and has repeatedly regulated the problem that reduces sealing effectiveness.
The technical scheme that the utility model adopts is: the concentric injection well downhole flow regulator of bridge-type; comprise the protection cylinder; the protection cylinder connects top connection and main body cylinder; main body cylinder connects lower contact; the inwall of main body cylinder is connected with interior water nozzle assembly and outer water nozzle assembly; the inwall of the outer wall of interior water nozzle assembly and outer water nozzle assembly is flexibly connected, and main body cylinder offers water filling port in its exposed section.
Characteristics of the present utility model also are,
Be flexibly connected by lead screw pair between main body cylinder, interior water nozzle assembly and outer water nozzle assembly, form a gap between interior water nozzle assembly and main body cylinder, the lower end in gap is the sand discharge hole.
The inside of top connection is provided with centering ring.
Be provided with back-up ring and the first sealing ring between interior water nozzle assembly and main body cylinder, between outer water nozzle assembly and main body cylinder, be provided with the second sealing ring, outer water nozzle assembly inwall be provided with bottom the 3rd sealing ring.
Outer water nozzle assembly connects lower contact by stop pin.
The beneficial effects of the utility model are: the concentric injection well downhole flow regulator of the utility model bridge-type can be realized excellent sand prevention card effect, aperture free adjustment, can repeatedly shut, be difficult for Ka Jing and easy to operate.Coordinate the integrated design of water filling governor motion in work, greatly simplified work progress, saved cost, market prospects are wide.
The accompanying drawing explanation
Fig. 1 is the structural representation of the concentric injection well downhole flow regulator of the utility model bridge-type.
In figure, 1. top connection, 2. centering ring, 3. main body cylinder, 4. protection cylinder, 5. interior water nozzle assembly; 6. back-up ring, 7. the first sealing ring, 8. the second sealing ring, 9. water filling port, 10. the 3rd sealing ring; 11. outer water nozzle assembly, 12. stop pins, 13. lower contacts, 14. sand discharge holes, 15. gaps.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The utility model provides a kind of bridge-type concentric injection well downhole flow regulator; as shown in Figure 1; comprise protection cylinder 4; protection cylinder 4 connects top connection 1 and main body cylinder 3; main body cylinder 3 connects lower contact 13; the inwall of main body cylinder 3 is connected with interior water nozzle assembly 5 and outer water nozzle assembly 11, and the inwall of the outer wall of interior water nozzle assembly 5 and outer water nozzle assembly 11 is flexibly connected, and main body cylinder 3 offers water filling port 9 in its exposed section.Between main body cylinder 3, interior water nozzle assembly 5 and outer water nozzle assembly 11, by lead screw pair, be flexibly connected, forming 15De lower end, 15, gap, a gap between interior water nozzle assembly 5 and main body cylinder 3 is sand discharge hole 14.The inside of top connection 1 is provided with centering ring 2.Be provided with back-up ring 6 and the first sealing ring 7 between interior water nozzle assembly 5 and main body cylinder 3, be provided with the second sealing ring 8 between outer water nozzle assembly 11 and main body cylinder 3, outer water nozzle assembly 11 inwalls be provided with bottom the 3rd sealing ring 10.Outer water nozzle assembly 11 connects lower contact 13 by stop pin 12.Wherein, the first sealing ring 7 and the 3rd sealing ring 10 adopt Glais ring, and the second sealing ring 8 adopts rubber ring.
The concentric injection well downhole flow regulator of the utility model bridge-type, in actual use, and water filling adjusting device cooperating, can realize Real-Time Monitoring.By the concentric injection well downhole flow regulator of this bridge-type routinely under operating procedure behind layer position, under the drive of water filling adjusting device, interior water nozzle assembly 5 moves up and down in the middle of water nozzle assembly 11 outside, reach the water filling port of outer water nozzle assembly 11 9 is opened to effect large or that turn down, thereby water injection rate also changes thereupon.When interior water nozzle assembly 5 moves in outer water nozzle assembly 11 the 3rd sealing ring 10 bottom, can shut fully.Now also can reach and test the envelope effect, test envelope work operation and time thereby greatly saved.
The concentric injection well downhole flow regulator of this bridge-type is in the underground work process, and water filling, by gap 15, is washed away this zone, makes whole device not have dead band, less scaling, husky card.The first sealing ring 7 and the 3rd sealing ring 10 adopt Glais rings, because the Glais ring friction factor is little, high temperature resistant, corrosion-resistant, in rotation process without creeping phenomenon, stable working, it is high that long term seal is regulated reliability.The effect of back-up ring 6 is to prevent that fine sand in the injecting process, dirt etc. from bringing in the first sealing ring 7 along with interior water nozzle assembly 5 up and down and causing the seal failure of the first sealing ring 7.The second sealing ring 8 adopts rubber ring.Because interior water nozzle assembly 5 has fit clearance with outer water nozzle assembly 11, dirt under high pressure can enter motion thread along gap, causes the screw thread burn into stuck, and rubber ring just can play the effect of protection motion thread.Stop pin 12 is for fixing outer water nozzle assembly 11.
Centering ring 2 can be smoothly falls the instruments such as side demodulating apparatus, drift size gauge tool along the central axis of main body cylinder 3, crooked and Ka Jing is not hampered in reason instrument dropping process.
