Description
Technical field
The utility model is related to petroleum works technical fields, are quickly sealed more specifically to a kind of novel continuous oil pipe
Stifled instrument.
Background technology
With the exploitation of the unconventionaloil pools well such as compact sandstone gas, shale gas, the construction volume with pressure for removing coiled tubing
It is substantially improved.When going out coiled tubing for pressure, it is necessary to carry out internal pressure closure and connection to disconnected pipe.The connection of onsite application
Device is mostly screw fastened formula, slip-type, groove pressing type etc., on the one hand can not achieve the quick connection of coiled tubing, it is necessary to scrape
Cut weld seam or in oil pipe surface rolling pit, another aspect can not also realize the closure of coiled tubing internal pressure, exist certain
Security risk.
The content of the invention
The technical problems to be solved in the utility model is, provides a kind of coiled tubing quick blocking instrument, can realize
The quick connection and effective closure of internal pressure of coiled tubing, it is ensured that quick blocking and the company of internal pressure are carried out to the pipe that breaks
It connects.
Technical solution is used by the utility model solves its technical problem：Construct a kind of coiled tubing quick blocking work
Tool, including connector and the support ring, gasket ring, cushion rubber, sleeve, slips, the cone that are sequentially sleeved on the outside of the connector, the company
Connector is also connected with auxiliary mounting rod, and for the connector with cone using being threadedly coupled, cone forms cone match with slips；
Using mounting rod drawing connector forward is aided in, connector band movable cone travels forward, and slips struts, the card of slips
Watt tooth bites coiled tubing inner wall, slips and cone locking；
Using mounting rod is aided in, by connector and centrum threaded engagement, cushion rubber is compressed, and realizes coiled tubing internal pressure
Closure.
In said program, the connector is equipped with the mounting hole with auxiliary mounting rod cooperation.
In said program, the surface of the support ring is equipped with weld seam slot.
In said program, the support ring is equipped with the ring roll slot coordinated with rolling tools.
In said program, the cushion rubber surface is equipped with weld seam slot.
In said program, the slips is three-clove style, is fixed by sealing ring.
In said program, the slips surface is equipped with hangnail.
In said program, the slips surface is equipped with weld seam slot.
Implement the coiled tubing quick blocking instrument of the utility model, have the advantages that：
1st, the utility model tool exterior surface is designed with weld seam slot, without carrying out scraping operations to coiled tubing weld seam, carries
High installation effectiveness；
2nd, the utility model in use, simple drawing operation, Bian Keshi is carried out by mounting hole to connector
The quick connection of existing coiled tubing；
3rd, the expansion of cushion rubber can be realized by the threaded engagement of cone and connector for the utility model, continuous so as to block
Oil pipe internal pressure；
4th, the utility model provides a variety of connection modes, in the case of extraneous conditions permit, is rolled using coiled tubing
Instrument realizes further connection；
5th, the utility model is simple in structure, easy for installation, quick detachable, it can be achieved that repeatedly using, reduction coiled tubing
Flow string acts the security risk of going out.
Description of the drawings
Below in conjunction with accompanying drawings and embodiments, the utility model is described in further detail, in attached drawing：
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the utility model and coiled tubing assembling schematic diagram；
In figure：1st, connector, 2, support ring, 3, gasket ring, 4, cushion rubber, 5, sleeve, 6, slips, 7, cone, 8,9,10, it is O-shaped
Circle, 11, auxiliary mounting rod, 12, coiled tubing.
Specific embodiment
For a clearer understanding of the technical features, objectives and effects of the utility model, it is detailed now to compare attached drawing
Illustrate specific embodiment of the present utility model.
As shown in Figure 1, 2, the utility model coiled tubing quick blocking instrument include connector 1, support ring 2, gasket ring 3,
Cushion rubber 4, sleeve 5, slips 6, cone 7, O-ring 8,9,10 aid in mounting rod 11 and coiled tubing 12.
Connector 1 is designed with mounting hole, and Fast Installation and closure are realized while shortening instrument overall dimensions.Connector 1
It is equipped with O-ring seal 8.
Annular groove and weld seam slot, the multiple connection and cooperation of implementation tool and coiled tubing 12 are designed in support ring 2.Glue
Circle 4 is compressed during connector 1 with the threaded engagement of cone 7, realizes the closure of coiled tubing internal pressure.
6 maximum outside diameter of slips is less than coiled tubing internal diameter, and coiled tubing 12 is inserted into convenient for instrument.Slips 6 is designed as three valves
Formula, three valve slips 6 are fixed using O-ring seal 9,10, realize strutting and tightening for slips 6.6 surface of slips is designed with weld seam
Slot so that slips 6 remains to realize with coiled tubing 12 good fit when strutting.The slip insert of slips 6 is barb structure, when continuous
When 12 lower end of oil pipe has the pressure to be communicated up, the further occlusion of slips 6 can be realized.
During installation, coiled tubing is sleeved on novel continuous oil pipe quick blocking tool exterior, using aid in mounting rod 11 to
Preceding drawing connector 1, by strutting for slips 6, slip insert bites 12 inner wall of coiled tubing, and implementation tool is fast with coiled tubing 12
Speed connection, at this time slips 6 and 7 locking of cone.The screw thread of connector 1 and cone 7 is screwed, compresses cushion rubber 4, cushion rubber expansion support backward
It opens and realizes the closure of 12 internal pressure of coiled tubing.Finally using rolling tools realize coiled tubing 12 and quick blocking instrument into
One step connects.
The embodiment of the utility model is described above in conjunction with attached drawing, but the utility model is not limited to
The specific embodiment stated, above-mentioned specific embodiment is only schematical rather than restricted, this field it is common
Technical staff is not departing from the utility model aims and scope of the claimed protection situation under the enlightenment of the utility model
Under, many forms can be also made, these are belonged within the protection of the utility model.
