Description
Technical field
The invention belongs to the drainage underground gas production tool in oil and gas exploitation field, more particularly to a kind of swab formula draining
Gas production plunger.
Background technology
Plunger lift water pumping gas production method is a kind of widely applied intermittent water pumping gas production measure.Plunger lift method can
To reduce shaft bottom hydrops, extend the gas well liquid loading time.Simultaneously plunger lift can be used for easy wax deposition, fouling oil/gas well, save
The process for removing cleaning wax, dirt.But there is also some problems, and it is big that such as production is discontinuous, the closed-in time is long, liquid wastage is lifted in rising
Deng.
Currently used water pumping gas production plunger has solid plunger, brush plunger, liner type plunger and quick plunger, common
Existing deficiency is to be unable to control the act liquid measure of plunger single work period and rise to lift liquid leakage seriously.When hydrops is excessive
When, piston tool can be caused to can not be successfully arrival well head, technique failure；When hydrops is less, strata pressure recovery time is short, column
It is slower to fill in speed uplink, rises and lifts the leakage of liquid process liquids seriously, plunger drain effect is poor.
Invention content
In order to overcome the defect of the above-mentioned prior art, the purpose of the present invention is to provide a kind of swab formula water pumping gas production columns
Plug may be implemented the sufficiently sealed of plunger and oil pipe, reduce the wastage of liquid, take full advantage of the energy of gas well, pass through
Sliding sleeve controls each work period lifting liquid measure, and plunger is made to be in optimum working efficiency state；Responding curve of well continuous production can be achieved.
In order to achieve the above object, the technical scheme is that：
A kind of swab formula water pumping gas production plunger, includes the plunger body 4 of hollow-core construction, and 4 inner cavity of plunger body is provided with
The sliding sleeve 2 of lower slider, 2 top of sliding sleeve are hollow-core construction, and internal channel 3 is circumferentially with four equally distributed sliding sleeve inlet openings 9；
2 bottom of sliding sleeve is equipped with claw 10；2 top of sliding sleeve is connected by screw thread and fishing head 1；
Cartridge 5 is inserted in the groove of plunger body 4, cartridge 5 is fixed by plunger lower half cylinder 7, plunger lower half
Cylinder 7 is connected by screw thread and plunger body 4；Plunger lower half cylinder 7 is circumferentially with four equally distributed inlet channels 14 and four
Equally distributed plunger inlet opening 8；7 inner wall of plunger lower half cylinder is equipped with claw locating slot 12, and 7 bottom of plunger lower half cylinder passes through spiral shell
Line is connect with spring pedestal 13, and spring 11 is sleeved on spring pedestal 13, and 11 one end of spring resists 2 lower face of sliding sleeve, and the other end supports
Firmly spring pedestal 13 is compressed in 7 inner cavity of plunger lower half cylinder；
5 inner diameter of cartridge from top to bottom gradually increases and plunger body 4 forms packing element inner cavity 6.
For plunger of the present invention in down stroke, hydrops flows to plunger upper part through sliding sleeve internal channel, realizes plunger fast downlink,
Upper liquid, which increases, to be pushed sliding sleeve to move down with respect to plunger lower half cylinder to make the locking position of claw to claw locating slot, and spring is replaced can be real
The existing single period lifts the change of liquid measure；Up stroke, plunger base gas through inlet channel acts on cartridge inner wall so that its
Expansion is adjacent to oil pipe, realizes the sufficiently sealed of plunger and oil pipe.
The present invention has the following advantages：
1, each work period lifting liquid measure is controlled by sliding sleeve, it can be achieved that responding curve of well continuous production, makes plunger be in most
Good working efficiency state.
2, there is a problem of that wastage is bigger for current plunger, filling for plunger and oil pipe may be implemented in plunger of the present invention
Divide sealing, reduces the wastage of liquid, take full advantage of the energy of gas well.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
Fig. 2 be the present invention plunger downlink and feed liquor during sliding sleeve internal channel opening state schematic diagram.
Fig. 3 is the partial enlarged view of the plunger inlet channel of the present invention.
Specific implementation mode
The invention will now be described in detail with reference to the accompanying drawings.
Referring to Fig.1, a kind of swab formula water pumping gas production plunger includes the plunger body 4 of hollow-core construction, 4 inner cavity of plunger body
It is provided with the sliding sleeve 2 slided up and down, 2 top of sliding sleeve is hollow-core construction, and internal channel 3 is circumferentially with four equally distributed sliding sleeves
Inlet opening 9；2 bottom of sliding sleeve is equipped with claw 10；2 top of sliding sleeve is connected by screw thread and fishing head 1；
Cartridge 5 is inserted in the groove of plunger body 4, cartridge 5 is fixed by plunger lower half cylinder 7, plunger lower half
Cylinder 7 is connected by screw thread and plunger body 4；With reference to Fig. 3, plunger lower half cylinder 7 is circumferentially with four equally distributed inlet channels
14 and four equally distributed plunger inlet openings 8；7 inner wall of plunger lower half cylinder is equipped with claw locating slot 12,7 bottom of plunger lower half cylinder
Portion is connect by screw thread with spring pedestal 13, and spring 11 is sleeved on spring pedestal 13, and 11 one end of spring resists 2 lower face of sliding sleeve,
The other end resists spring pedestal 13 and is compressed in 7 inner cavity of plunger lower half cylinder；
5 inner diameter of cartridge from top to bottom gradually increases and plunger body 4 forms packing element inner cavity 6.
The plunger descending phase is as shown in Fig. 2, equally distributed four inlet openings 8 on the plunger and be located at sliding sleeve
Upper equally distributed four sliding sleeve inlet openings 9 connection, liquid enter sliding sleeve internal channel 3 to plunger upper part by inlet opening, realize
Fast downlink of the plunger in hydrops.After plunger reaches shaft bottom, plunger inlet opening 8 still keeps being connected to sliding sleeve inlet opening, with
The liquid of plunger upper part gradually accumulates, and liquid load gradually increases, and fluid column load directly acts on sliding sleeve inner bottom surface, supports plunger
The spring 11 of sliding sleeve is gradually compressed, and sliding sleeve 2 is with respect to 7 downlink of plunger lower half cylinder.It is taken when hydrops amount reaches the critical of Plunger Lift
When liquid measure, sliding sleeve 2 comes downwards to the closed position of sliding sleeve inlet opening 9 and plunger inlet opening 8, and the plunger for forming sealing is whole.Sliding sleeve
Lower end claw 10 is caught in claw locating slot 12, is realized the seat card of sliding sleeve, is kept the closing in channel.
The plunger uplink stage, plunger lower gas passed through position as shown in Figure 1, plunger inlet opening 8 is closed
Packing element inner cavity 6, work of the cartridge 5 in gas pressure are entered in 7 equally distributed four inlet channels 14 of plunger lower half cylinder
With lower expansion close to oil pipe, achieve the effect that sufficiently sealed, reduces the leakage of plunger upper part liquid, it is abundant that gas well is utilized
Energy.After plunger reaches well head, upper liquid is discharged, and plunger sliding sleeve 2 under the action of catcher is restored to sliding sleeve inlet opening 9
The state being connected to plunger inlet opening 8, with the output of gas, cartridge 5 is gradually restored to original state, completes a week
Phase.
