Description
Technical field
This utility model relates to a kind of petroleum and natural gas quarrying apparatus, particularly to a kind of Multi-stage plunger gas-lift production dress
Put.
Background technology
Plug gaslift is a kind of important artificial lifting way.It is external that as far back as nineteen fifties, just someone is engaged in plunger lift
The research of method for designing.After plunger lift technique is the most successful, this technology is as important artificial lift
Technique has obtained wide publicity at home, and to the structure of plunger, the characteristics of motion, optimization design, recovering the oil and draining is adopted
Application in gas well etc. have carried out wide research.Plunger lift extracting device of oil used in oil exploitation now is than oil pumping
Facility have equipment investment few, and mounting cost is low, and efficiency is high and can arbitrarily adjust the advantages such as running parameter, and generally plunger lift is adopted
Oil device uses and once lifts, and single stroke is long, and consumable accessory loss is fast, buffering difficulty.In deep-well, shortcoming is particularly evident, if taking out
Oil machine then can inefficiency, even without benefit.
Summary of the invention
The purpose of this utility model is: provide a kind of Multi-stage plunger gas-lift production device.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of Multi-stage plunger gas-lift production device,
Device include sleeve pipe, oil pipe, buffer spring a, plunger switch a, plunger a, block a, buffer spring b, plunger switch b, plunger b,
Block b.It is characterized in that: sleeve pipe is positioned at outer layer, oil pipe is positioned at sleeve pipe；Buffer spring a hollow and be fixed on oil pipe bottom, its
Being arranged above plunger a, plunger a hollow, plunger switch a is positioned at plunger a；Block a, block a is had to be fixed on oil pipe above plunger a
In；Buffer spring b hollow and be fixed on above block a, it is arranged above plunger b, plunger b hollow, and plunger switch b is positioned at plunger b
In；Block b, block b is had to be fixed in oil pipe above plunger b.
This utility model has the advantages that (1) multistage lifting, reduces single stroke, reduces abrasion；(2) strengthen
Deep-well plunger lift ability；(3) requirement to buffering is reduced.
Accompanying drawing explanation
Fig. 1 is internal structure cross-sectional schematic of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings, this utility model is described in detail.
As it is shown in figure 1, in order to achieve the above object, this utility model by the following technical solutions: device include sleeve pipe 1,
Oil pipe 2, buffer spring a3, plunger switch a4, plunger a5, block a6, buffer spring b7, plunger switch b8, plunger b9, block
b10.It is characterized in that: sleeve pipe 1 is positioned at outer layer, oil pipe 2 is positioned at sleeve pipe；Buffer spring a3 hollow and be fixed on oil pipe 2 bottom,
It is arranged above plunger a5, plunger a5 hollow, and plunger switch a4 is positioned at plunger a5；There are block a6, block a6 solid above plunger a5
It is scheduled in oil pipe 2；Buffer spring b7 hollow and be fixed on above block a6, it is arranged above plunger b9, and plunger b9 hollow, plunger is opened
Close b8 and be positioned at plunger b9；Block b10, block b10 is had to be fixed in oil pipe 2 above plunger b9.
Described plunger switch a4 is for controlling the opening and closing of plunger a5 hollow channel.
Described plunger switch b8 is for controlling the opening and closing of plunger b9 hollow channel.
Described block a6 is used for stoping plunger a5 to continue to rise.
Described block b10 is used for stoping plunger b9 to continue to rise.
As it is shown in figure 1, the method that this utility model realizes Multi-stage plunger gas-lift production is: lifting gas by sleeve pipe 1 with
Annular space between oil pipe 2 enters oil pipe 2.Plunger switch a4 is closed, and plunger switch b8 is opened, on lifting gas push plunger a5
Rise, drive fluid column to rise simultaneously.Stopping when plunger a5 rises to block a6 rising, fluid column is extruded to above plunger b9.Post
Plug switch a4 opens, and plunger switch b8 is closed, and lifting gas is begun to decline under gravity by plunger a5, plunger a5, post
Plug b9 rises under lifting gas push.Stopping when plunger b9 rises to block 10 rising, fluid column is discharged well head.Plunger a5
Dropping down onto shaft bottom, plunger switch a4 is closed, and plunger switch b8 is opened, and moves in circles.
This utility model, compared with traditional plunger lift, have employed the mode of Multi-stage plunger gaslift, considerably reduces
Stroke, thus reduce the loss of easily worn part, extend the service life of entirety；Solve deep-well plunger lift efficiency low,
The difficult problem being difficult to, and it is greatly reduced the requirement to buffering, there is bigger practicality and certain market prospect.
