Abstract
The utility model relates to one kind to be sent into riser pipe device for jack-up unit, is made of device noumenon, described device includes central tube, top belt lacing outer cylinder and marine riser, is provided with the cover board with exhaust valve on the outer cylinder connector；The outer tube is provided with the central tube of both ends belt lacing, the cover board of outer cylinder is stretched out at the top of the central tube, the outer tube between double card spring button and the marine riser by connecting, what the device had not only been able to achieve conventional jack-up platform marine riser running tool fetches and delivers marine riser function, but also tubing string realizes the well cementing operation of surface layer marine riser in capable of connecting.
Description
Technical field:
The technical field of the utility model is related to oil recovery auxiliary tool, more particularly to it is a kind of for jack-up unit be sent into every
Water conduit device.
Background technique
Traditional jack-up unit riser pipe well cementation is cemented the well using the method for inner tube insertion.Interior tubing string insertion is solid
After well will appear insertion head insertion difficulty and is inserted into practice process situations such as seal failure, interior tubing string well cementation also needs
2 centralizers are added on drilling rod, are dismantled 2 centralizers and are probably needed to spend 1.5h；And if having situations such as being hampered during tripping in,
It can only cement the well on the spot and open operation to next in this way and bring certain hidden danger；After the increase possibility of exploration dynamics and difficulty
Well surface layer marine riser under membership it is deeper, phenomena such as may building the pressure during cement the well or get through in this way, inserted using tradition
Enter method well cementation, if there is the not good solution that builds the pressure just.
In order to solve insertion sealing, to save tubing string well cementation handling centralizer time, marine riser tripping in tradition not in place with
And situations such as building the pressure, it is necessary to which design studies one novel tools solves the problems, such as that these are common, which comes out
It solves the problems, such as insertion sealing blow-by, also can handle some complex situations during well cementation, operation can be effectively reduced
Risk and cost.
Utility model content
The utility model is to solve technical problem present in well-known technique and provide one kind and be both able to achieve conventional jack-up
Platform marine riser running tool fetches and delivers marine riser function, and can connect the dress that interior tubing string realizes the well cementing operation of surface layer marine riser
It sets.
The utility model be solve well-known technique present in technical problem and the technical solution adopted is that:
One kind for jack-up unit be sent into riser pipe device, be made of device noumenon, described device include central tube,
Top belt lacing outer cylinder and marine riser are provided with the cover board with exhaust valve on the outer cylinder connector；The outer barrel is provided with
The central tube of both ends belt lacing, stretches out the cover board of outer cylinder at the top of the central tube, the outer cylinder by double card spring buckle with it is described every
It is connected between water pipe.The central tube top contact is 450cm~600cm apart from cover board.
The exhaust valve is apart from outer cylinder inside edge between 150cm~400cm.
Two end connector internal diameters of the central tube are 16cm~17cm；The outer cylinder top contact internal diameter is
75cm~77cm.
The double card spring, which is buckled, is provided with sealing ring.
Beneficial effect
1, the utility model is designed by " banjo connector ", it is ensured that is realized in the case where all filling seawater in marine riser solid
Well.
2, the central tube lower connector of the utility model is connect with drilling rod, and drilling rod is with long to the above 3-5m of float shoe, Ke Yibao
Least cement plug amount is stayed in marine riser between card cementing phase.
3, the utility model has the tensile strength of 150T, is able to satisfy the feeding demand of marine riser.
4, the double card spring button of the utility model outer barrel is sealed by a seal ring, and bearing capacity is not less than
7Mpa guarantees not leak during well cementation.
Detailed description of the invention
Fig. 1 is that the utility model is one kind for jack-up unit feeding riser pipe apparatus structure schematic diagram.
Specific embodiment
In order to further appreciate that the contents, features and effects of the utility model, following instance is lifted, and cooperate attached drawing detailed
It is described as follows:
As shown in Figure 1, the utility model, which provides one kind, is sent into riser pipe device for jack-up unit, by device noumenon
It constitutes, described device includes central tube 1,21 outer cylinder 2 of top belt lacing and marine riser 3, is provided with band on the outer cylinder connector 21
The cover board 23 of exhaust valve 22；The exhaust valve 22 is apart from outer cylinder inside edge between 150cm~400cm.Inside the outer cylinder 2
It is provided with the central tube 1 of both ends belt lacing (11,12), two end connector internal diameters of the central tube are 16cm~17cm；Institute
Stating outer cylinder top contact internal diameter is 75cm~77cm.The utility model is solved by " banjo connector " transformation with well depth
It is continuously increased, occurs under riser pipe increasing deeply when being hampered, side punching becomes lower riser pipe technical problem.In addition, the utility model
" banjo connector " can with up and down pipe string, when the complex situations such as build the pressure during processing burst well cementation more than some processing arrange
It applies.The cover board 22 of outer cylinder is stretched out at the top of the central tube 1, the central tube top contact is 450cm~600cm apart from cover board.
The outer cylinder 2 is buckled by double card spring and is connected between (31,32) and the marine riser 3.It is provided on the double card spring button (31,32)
Sealing ring 33.In actual production, the internal diameter of 1 twin adapter of central tube (11,12) is 16.8cm, and 2 top contact internal diameter of outer cylinder is
76.2cm, exhaust valve 22 is apart from outer cylinder inward flange 350cm.
The utility model application method one:
It is live then play a cylindrical drill bar immediately if 1, traditional insertion sealing can not seal, according to the pipe string prepared in advance,
The present apparatus is connected；
2, the present apparatus is sent to well head lower platform, and is linked with marine riser, and will fill seawater in pipe and (open exhaust valve row
Gas), interior tubing string is apart from float shoe 3-5m.
3, exhaust valve, water flowing, well cementation are closed after filling seawater.
The utility model application method two:
1, according to the conduit table tripping in present apparatus；
2, the present apparatus is seated at turntable surface, and tripping in prepares drilling rod (run of steel 5m shorter than present apparatus length or so, the company of length
It connects " concentric reducer ", opens exhaust valve；
3, marine riser is seated at well head chain-wales, connects top and drives, to marine riser inside fill seawater and (seen whether by exhaust valve
Fill seawater)；
4, exhaust valve is closed after filling seawater, top is logical, circulation, is cemented the well according to cementing design (solid with semisubmersible platform
Well is similar).
The above mentioned embodiment is only schematical, rather than restrictive, those skilled in the art
Under the enlightenment of the utility model, in the case where not departing from the utility model aims and claimed range, may be used also
To make many variations, these belong to the column of the protection of the utility model.
