Abstract
The present invention relates to oil extraction in oil field field of engineering technology, and ejection device on the automatic preventing oil pipe of box cupling can be crossed by belonging to a kind of slip-type.The present invention solves the problems, such as that general control system automatic can not cross tubing coupling, anti-above roof construction is insecure, need to manually open anti-upper top function.It is by upper shell（1）, slip segment（2）, slip spider（3）, elasticity reset device（4）And lower housing（5）Composition；Wherein upper shell（1）Internal and slip segment（2）Contact, slip segment（2）Mounted on slip spider（3）On, slip spider（3）Position is by upper shell（1）It limits, elasticity reset device（4）Lower end and lower housing（5）Contact；Lower housing（5）With upper shell（1）It is threadedly coupled.The advantages that present invention has crosses box cupling without human intervention in oil pipe decentralization process, and automatic clamping is pushed up on oil pipe, easy to operate, reduction operating risk.
Description
Technical field
The present invention relates to oil extraction in oil field field of engineering technology, carry out well-flushing, sand washing process using Coupled tubing, particularly
Wax removal de-plugging operation, ejection device on the automatic preventing oil pipe of box cupling can be crossed by belonging to a kind of slip-type.
Background technology
At present in oilfield oil well well workover technology field, well-flushing, sand washing process are carried out using Coupled tubing, it is particularly clear
Wax de-plugging operation since well-flushing pressure and liquid friction force act on, can cause to push up on well-flushing oil pipe.There are nothings for general control system
Method automatically by tubing coupling, anti-upper roof construction is insecure, need manually to open in high-pressure area pushed up on anti-function etc. it is dangerous and
Inefficient factor, therefore devise slip-type and can cross ejection device on the automatic preventing oil pipe of box cupling.
The content of the invention
Cross box cupling without manual intervention in oil pipe decentralization process the object of the present invention is to provide one kind, realize well-flushing,
The slip-type for the function that sand washing decentralization Tubing During Running holds oil pipe tightly automatically can cross ejection device on the automatic preventing oil pipe of box cupling.
The technical scheme is that：It is made of upper shell, slip segment, slip spider, elasticity reset device and lower housing；
It is wherein contacted inside upper shell with slip segment, slip segment is mounted on slip spider, and slip spider position is limited by upper shell, slip spider
Lower section is supported by elasticity reset device；Elasticity reset device lower end is contacted with lower housing；Lower housing is threadedly coupled with upper shell.
It can radially be moved freely in the horizontal direction between slips and slip spider, slips top is provided with fillet surface, slips
Seat lower section is supported by elasticity reset device.
Taper surface is used between upper shell and slip segment.
Slip spider is limited by upper shell and moved in the vertical direction.
Compared with the prior art the present invention has the following advantages that：
1）, the present invention box cupling is crossed in oil pipe decentralization process without manual intervention, realize well-flushing, sand washing decentralization Tubing During Running from
The dynamic function of holding oil pipe tightly；
2）, between upper shell and slips using taper surface, when slips goes upward to extreme position, form taper-face contact, it is securely steady
It is fixed；
3）, handle by operating slip spider both ends, slip spider can be bounced rapidly, make device into anti-upper top working condition, behaviour
Make simple.
Description of the drawings：Fig. 1 is schematic structural view of the invention；Fig. 2 is of the invention and with box cupling oil
Pipe cooperating schematic diagram.
Specific embodiment：The invention will be further described below in conjunction with the accompanying drawings：It is by upper shell 1, slip segment 2, card
Watt seat 3, elasticity reset device 4 and lower housing 5 form；Wherein 1 inside of upper shell is contacted with slip segment 2, and slip segment 2 is mounted on card
On watt seat 3,3 position of slip spider is limited by upper shell 1, and 3 lower section of slip spider is supported by elasticity reset device 4；Elasticity reset device 4
Lower end is contacted with lower housing 5；Lower housing 5 is threadedly coupled with upper shell 1.
It can radially be moved freely in the horizontal direction between slips 2 and slip spider 3,2 top of slips is provided with fillet surface, card
3 lower section of watt seat is supported by elasticity reset device 4.
Taper surface is used between upper shell 1 and slip segment 2.
Slip spider 3 is limited by upper shell 1 and moved in the vertical direction.
At the scene in application, lower housing 5 is fixed on the well control instrument of lower section with bolt, you can start from upper shell 1
The opening tripping in Coupled tubing of top carries out the operations such as well-flushing, sand washing.Due to using level between slips 2 and slip spider 3
The connection mode that can move freely on direction is moved downward in tubing coupling 7, when touching the fillet surface on 2 top of slips, by card
Watts 2 push down on together with slip spider 3, meanwhile, slips 2 along oil pipe 6, radially outward move by side, passes through tubing coupling 7.Oil
For pipe box cupling 7 by rear, elasticity reset device 4 promotes 2 uplink of slip spider 3 and slips, while slips 2 is along the radially-inwardly side of oil pipe 6
It is mobile, hold oil pipe 6 tightly again.Realize the characteristics of can crossing box cupling.Simultaneously as box cupling is crossed in oil pipe decentralization process without people
Work intervention realizes well-flushing, sand washing decentralization Tubing During Running holds oil pipe, function of the worker away from high-pressure area tightly automatically.
When being pushed up on oil pipe, the taper surface between upper shell 1 and slips 2 forms cone when slips 2 goes upward to extreme position
Face contacts, firm stable.It is not required on control oil pipe when pushing up, locking structure is designed between slip spider 3 and upper shell 1, in card
When watt seat 3 is pressed into extreme lower position, extreme lower position can be locked in, while in discontiguous between slip insert 2 and oil pipe 6
State, can normally on put drain line.It, can be rapid by operating the handle at 3 both ends of slip spider when needing to open anti-upper top function
Slip spider 3 is bounced, into anti-upper top working condition.
