Description
Technical field
This utility model is related to petroleum and natural gas exploitation field, specifically a kind of liquid discharging gas producing piston tool.
Background technology
Gas lift plunger is to apply the device for isolating gas-liquid in oil-gas field development well, the solid interface as gas-liquid, to subtract
The slippage for altering liquid and liquid of few oil gas.At present, domestic and international Plunger Lift crude oil and production gas production are all service intermittent modes,
I.e. after Plunger Lift liquid reaches well head, the closes a well in plunger that just can make of needs falls shaft bottom again.The folding of valve body used
Complete by clashing into upper and lower fastener or alternate manner.When plunger is descending, due to plunger and oil pipe gap and bypass all very
It is little, make plunger downstream rate very slow, can not rely in opening well and making production and shaft bottom, i.e. operating mode are fallen under deadweight automatically for interval
Formula, it is impossible to realize continuous production.
The content of the invention

Quantity-produced liquid discharging gas producing piston tool on the premise of closing a well in.
The technical solution adopted in the utility model is, a kind of liquid discharging gas producing piston tool, including piston cylinder and is matched with
The ball sealer of piston cylinder internal diameter, the piston cylinder is the annular space structure of lower ending opening, is provided with piston plate in the annular space, the piston
Plate be provided with least one it is axially extending go out piston cylinder connecting rod, the end of the connecting rod is the snap finger for bending inwards；The sealing
Ball is assemblied on the center-pole in piston cylinder, be provided with the center-pole below the ball sealer spaced apart upper limit key and under
Positive stop key.
Connecting rod on the piston plate is two, and their circumference is distributed on piston plate.
The stroke of the distance between the upper limit key and lower limit key less than or equal to piston plate in piston cylinder.
The stroke of the distance between the ball sealer and upper limit key less than or equal to piston plate in piston cylinder.
Piston cylinder is extended in the upper end of the center-pole, and connects fishing head.
Further, the instrument also includes protection sleeve, and the internal diameter of the protection sleeve is more than the connecting rod ring week on piston plate
The external diameter of movement locus.
Further, multiple through holes are provided with the protection sleeve.
The beneficial effects of the utility model are：This utility model is not only simple in structure, and can stop production in responding curve of well
Under the premise of, realize quantity-produced purpose.

Specific embodiment
Referring to shown in Fig. 1, Fig. 2：This utility model is a kind of liquid discharging gas producing piston tool, including piston cylinder 1 and matching
In the ball sealer 2 of the internal diameter of piston cylinder 1.
Above-mentioned piston cylinder 1 for lower ending opening annular space structure, the annular space（The annular space chamber 3 that finger ring hollow structure is constituted）Interior setting
Have the piston plate 11 of matching, the piston plate 11 be provided with least one it is axially extending go out piston cylinder 1 connecting rod 4, this utility model
Connecting rod 4 on described piston plate 11 is two, and they are circumferentially distributed on piston plate 11.The end of the connecting rod 4 is to inflection
The snap finger of folding；The ball sealer 2 is assemblied on the center-pole in piston cylinder 1, is provided with the center-pole 5 of the lower section of ball sealer 2
Spaced apart upper limit key 6 and lower limit key 7, the snap finger is in back and forth is transported between upper limit key 6 and lower limit key 7 all the time
It is dynamic.Wherein, the row of the distance between the upper limit key 6 and lower limit key 7 less than or equal to piston plate 11 in piston cylinder 1
Journey.The stroke of the distance between the ball sealer 2 and upper limit key 6 less than or equal to piston plate 11 in piston cylinder 1.To reach
Optimum effect.
In addition, piston cylinder 1 is extended in the upper end of center-pole 5, and connect fishing head 10, be easy to liquid discharging gas producing piston tool
Well is salvaged when needing to change, keeping in repair；The instrument also includes protection sleeve 8, and the internal diameter of the protection sleeve 8 is more than piston plate 11
On the ring of connecting rod 4 week movement locus external diameter, be provided with multiple through holes on the protection sleeve 8.To reach protection plunger tool interior
Part be not damaged by.
Above-mentioned piston cylinder 1, the protection outer wall of sleeve 8 are provided with spaced apart cannelure 9, during realizing plunger lift
Turbulent flow is sealed.
The course of work：
When piston tool is descending in down-hole, down-hole pressure increases, and piston cylinder 1 is inside and outside to have pressure differential, the meeting of piston plate 11
Move on occurring under external pressure effect, and then move on drivening rod 4, when the stroke of connecting rod 4 reaches upper limit key 6, the band of connecting rod 4
Move on dynamic upper limit key 6, upper limit key 6 and center-pole 5 are synchronously touched in shifting in generation, and then drive ball sealer 2 and move, close
The internal diameter of the sealing piston cylinder 1 of blocking 2, realizes the closing of plunger central passage；
When piston tool is up in down-hole, down-hole pressure reduces, and piston cylinder 1 is inside and outside to have pressure reduction, piston plate 11
Lose external pressure effect to issue and give birth to shifting, and then drivening rod 4 is moved down, when the stroke of connecting rod 4 reaches lower limit key 7, connecting rod 4
Drive lower limit key 7 to move down, the center-pole 5 synchronous with center-pole 5 of lower limit key 7 is touched and moves down, and then drive ball sealer 2
Lower movement, ball sealer 2 opens the internal diameter of sealing piston cylinder 1, realizes the opening of plunger central passage.
Above concrete technical scheme only to illustrate this utility model, rather than a limitation.Although with reference to above-mentioned concrete skill
Art scheme has been described in detail to this utility model, it will be understood by those within the art that：It still can be right
Above-mentioned concrete technical scheme is modified, or carries out equivalent to which part technical characteristic；And these are changed or replace
Change, the essence for not making appropriate technical solution departs from spirit and scope of the present utility model.
